Re: [BackupPC-users] rsync via ssh/rrsync

2024-05-23 Thread Mike Hughes

I think you're having some confusion about what that clause in authorized_keys 
does. According to [1], it basically executes the command for you. So when the 
backuppc user creates the ssh connection, it runs:
'/usr/bin/rrsync /'
on the target. You don't need to "initiate" the rsync in this way because 
BackupPC manages that, once you select rsync as the method. All you need to do 
is permit rsync to run, which is not accomplished in the authorized_keys file.
Remove that restriction.

Additionally, if you are connecting as the backuppc user, what provides that 
user permission to rsync the files? In my case, I followed this tip from the 
manual [2] and added an entry in /etc/sudoers (edited with visudo) to allow 
backuppc to run rsync without a password prompt:

## Allow backuppc user to use rsync
backuppc  ALL=NOPASSWD: /usr/bin/rsync --server *

Hope this helps!

[1]https://serverfault.com/a/803873/125737
[2] 
$Conf{RsyncClientPath}
 = 'sudo /usr/bin/rsync';

This is the command in authorized_keys:

command="/usr/bin/rrsync /",restrict,from=

So it should allow rsync to access to the full server, as expected,
but BPC doesn't show any files in the backup

Re: [BackupPC-users] PingCmd no longer having effect

2024-04-05 Thread Mike Hughes

Hi Ian,

I'm not sure why it would suddenly stop working for you as that seems like a 
completely legitimate solution.
FWIW, this is the command I use for unpingable clients:
$Conf{PingCmd} = '/bin/echo $host';

Best of luck!

Subject: [BackupPC-users] PingCmd no longer having effect

Hi,

I've been using BackupPC for many years now, and have used /usr/bin/true as the 
ping command for hosts that can't respond to ping.  However after a reboot on 
January 31st, my server stopped obeying pingcmd and stopped backing up those 
hosts due to lack of ping response.  I am using BackupPC 4.4.0-5ubuntu2 amd64 
on Ubuntu 22.04.

So far I have tried:

Overriding $Conf{PingCmd}, $Conf{PingPath}, and $Conf{Ping6Path} in the global 
config from webui and config file.

Setting  $Conf{PingCmd} in the client config to either /usr/bin/true or ping 
-c1 127.0.0.1 using webui and config file.

None of the above seem to make any difference at all anymore.  No matter what I 
set, I restart the service and get the same error:

2024-04-05 13:58:38 can't ping  (client = myclient.com); exiting


However I can confirm other changes to the client config files do have an 
effect.  For example setting a ClientNameAlias in the client config works.

I also tried deleting the client config file and allowing the webui to create 
it, and doing an apt-get --reinstall install backuppc.  Same effect.

I'm wondering if anyone has noticed anything similar, or has advice on how to 
debug.

Thanks,
Ian

Re: [BackupPC-users] How to run a manual backup.

2024-03-04 Thread Mike Hughes

Hi Tony,

If you're stuck at the ssh part, you won't be successful running a backup as 
making the connection is the first step.
What happens when you try to ssh to this client from the backuppc account on 
the backup server? Assume you've already tried ssh-copy-id but it's failing. 
I'm having trouble imagining what part of an upgrade would have broken a 
functional ssh key pairing unless the IP address changed.

As for a local backup you could use rsync to copy home to another partition:

rsync -a dir1/ dir2

I believe a later version was posted and is indeed necessary for v4
since:
- The notion of how incrementals are constructed from fulls has been
  inverted
- The format of the attrib files has changed extensively
- The pool hierarchy, naming convention, and storage format have
  changed
- Xattrs are now supported

Look through the archives... it was posted since v4 somewhere...

Re: [BackupPC-users] HELP - FW: BackupPC administrative attention needed

2022-03-24 Thread Mike Hughes

Hi Edward,

I'm not sure how much help this list can be as we are just a group of people 
who administrate our own installations of BackupPC. It's a very flexible 
solution that can handle massive amounts of backup and runs maintenance-free 
for years, so it's not a surprise if it got forgotten about until the disk 
filled up.

Most of the folks on this list installed the software ourselves. The "PC Backup 
Genie" is just a cutesy name attributed to the process that sent the email. Can 
you reach out to the individual responsible for the installation of the system? 
 If it's not possible to contact the person in charge of the BackupPC build, 
the best clue to find the filled disk is to identify the originating server of 
any alerts such as the one below to lead you to the source.

As the Senior IT Admin you're familiar with the spoofability of the "FROM" 
address on an email. There's no guarantee that it came from the "remote05" 
server, but check that first as a simple first step. If that server isn't 
running BackupPC then contact your email administrator to ask for a mail trace 
to determine which server sent it.

Since you're targeting /var, the directory to exclude would be /log, not

[BackupPC-users] maintaining exclusion templates

2021-05-20 Thread Mike Hughes

Hi BackupPC users,

I'd like to maintain several templates for exclusion lists to be available 
across all clients. For example, the LINUX_WWW template might exclude these 
directories:
/proc
/sys
/home/this_user
/mnt/this_network_share
/tmp
etc.

And the LINUX_SQL template might exclude:
/proc
/sys
/var/lib/mysql

The goal would be to apply the templates across multiple clients while not 
interfering with updates. Any perl pros out there already doing something 
similar?

I did have a 'my @common_excludes' variable created in each client's config, 
but this gets messy, especially when the configs are edited via the GUI.

Thanks for any tips!
Mike

You can always break a backup job into multiple backup 'hosts' by using the

Subject: [BackupPC-users] Handling machines too large to back themselves up

I have a server which I'm not able to back up because, apparently, it's just 
too big.

If you remember me asking about synology's weird rsync a couple weeks ago, it's 
that machine again.  We finally solved the rsync issues by ditching the 
synology rync entirely and installing one built from standard rsync source code 
and using that instead.  Using that, we were able to get one "full" backup, but 
it missed a bunch of files because we forgot to use sudo when we did it.  (The 
synology rsync is set up to run suid root and is hardcoded to not allow root to 
run it, so we had to take sudo out for that, then forgot to add it back in when 
we switched to standard rsync.)

Since then, every attempted backup has failed, either full or incremental, 
because the synology is running out of memory:

This is the rsync child about to exec /usr/libexec/backuppc-rsync/rsync_bpc
Xfer PIDs are now 1228998,1229014
xferPids 1228998,1229014
ERROR: out of memory in receive_sums [sender]
rsync error: error allocating core memory buffers (code 22) at util2.c(118) 
[sender=3.2.0dev]
Done: 0 errors, 0 filesExist, 0 sizeExist, 0 sizeExistComp, 0 filesTotal, 0 
sizeTotal, 0 filesNew, 0 sizeNew, 0 sizeNewComp, 32863617 inode
rsync_bpc: [generator] write error: Broken pipe (32)

The poor little NAS has only 6G of RAM vs. 9.4 TB of files (configured as two 
sharenames, /volume1 (8.5T) and /volume2 (885G) and doesn't seem up to the task 
of updating that much at once via rsync.

Adding insult to injury, even a failed attempt to back it up causes the bpc 
server to take 45 minutes to copy the directory structure from the previous 
backup before it even attempts to connect, and then 12-14 hours doing reference 
counts after it finishes backing up nothing.  Which makes trial-and-error 
painfully slow, since we can only try one thing, at most, each day.

In our last attempt, I tried flipping the order of the RsyncShareNames to do 
/volume2 first, thinking it might successfully back up the smaller share 
successfully before running out of memory trying to process the larger one.  It 
did not run out of memory... but it did sit there for a full 24 hours with one 
CPU (out of four) running pegged at 99% handling the rsync process before we 
finally put it out of its misery.  The bpc xferlog recorded that the connection 
was closed unexpectedly (which is fair, since we killed the other end) after 
3182 bytes were received, so the client clearly hadn't started sending data 
yet.  And now, after that attempt, the bpc server still lists the status as 
"refCnt #2" another 24 hours after the client-side rsync was killed.

So, aside from adding RAM, is there anything else we can do to try to work 
around this?  Would it be possible to break this one backup down into smaller 
chunks that are still recognized as a single host (so they run in sequence and 
don't get scheduled concurrently), but don't require the client to diff large 
amounts of data in one go, and maybe also speed up the reference counting a bit?

An "optimization" (or at least an option) to completely skip the reference 
count updates after a backup fails with zero files received (and, therefore, no 
new/changed references to worry about) might also not be a bad idea.

Re: [BackupPC-users] [BackupPC-devel] BackupPC 4.4.0 released

2020-06-29 Thread Mike Hughes

For what it's worth, I was able to resolve this (for now) by updating CPAN 
itself. I noticed when running certain commands that it complained that CPAN 
was at version 1.x and version 2.28 was available. It suggested running:
install CPAN
reload cpan

But those are clearly not bash commands. They need to be run in the CPAN shell:
# perl -MCPAN -e shell

After completing, I again ran the following as the backuppc user and it 
reported the correct version:
$ /usr/bin/perl -e 'use BackupPC::XS; print("$BackupPC::XS::VERSION\n")'
0.62

This is likely not the best way to resolve a mismatched cpan module version but 
it does appear to have worked for me, for now. I promise not to complain next 
time an update comes through and I end up having to rebuild from .iso 

You can install the perl module Module::Path to find the path for a module.

After installing, do this:
perl -e 'use Module::Path "module_path"; 
print(module_path("BackupPC::XS")."\n");'

Example output:
/usr/local/lib/x86_64-linux-gnu/perl/5.26.1/BackupPC/XS.pm

Now try as root and the BackupPC user to see the difference.  Does the BackupPC 
user have permission to access the version root uses?

You can also print the module search path with:
perl -e 'print join("\n", @INC),"\n"'

Does that differ between root and the BackupPC user?

That's why you want to stick to all packaged modules whenever
possible.   Over time, dependencies can change and the packaged
versions will update together.  You can probably update a cpan module
to the correct version manually but you need to track all the version
dependencies yourself.   There are some different approaches to
removing modules: https://www.perlmonks.org/?node_id=1134981

Well, I'm not sure how to clean up the mess, but the problem is simple. You 
don't want to mix manual cpan installs with packages. There's no reason to use 
cpan at all if you're using my packages.

My guess is the cpan installs are going into /usr/local which is overriding the 
package installs.

Subject: [BackupPC-users] FEATURE REQUEST: More robust error reporting/emailing

It would be great if there could be a way to have a host/share
configurable way to trigger emails based on certain types of errors or
changes.

The goal being to avoid the "complacency" of backups continuing to run
but not being aware of either continuing backup errors or unexpected
changes to the underlying system.

Otherwise, one must rely on regular and pretty detailed review of logs
and stats.

Helpful configurable options would include:
- *Days* since last successful backup - *per host* configurable - as you
  may want to be more paranoid about certain hosts versus others while
  others you may not care if it gets backed up regularly and you want
  to avoid the "nag" emails

- *Number* of errors in last backup - *per host/per share*
  configurable - Idea being that some hosts may naturally have more
  errors due to locked files or fleeting files while other shares may
  be rock stable. (Potentially, one could even trigger on types of errors
  or you could exclude certain types of errors from the count)

- *Percent* of files changed/added/deleted in last backup relative to
  prior backup - *per host/per share* configurable - idea here being
  that you want to be alerted if something unexpected has changed on
  the host which could even be dramatic if a share has been damaged or
  deleted or not mounted etc.

Just a thought starter... I'm sure others may have other ideas to add...

It's possible you have two different versions of perl installed, or for some

Try some of the suggestions here:

Yes, I just did a fresh install and didn't have any issues (with BackupPC-XS). 
I DID find that /var/run/BackupPC is not created by the package and cannot be 
created automatically since BackupPC is run as the backuppc user. Looking into 
that now.

[BackupPC-users] replication of data pool

2020-05-20 Thread Mike Hughes

Hi, we're currently syncing our cpool to an off-site location on a weekly 
basis. Would it be feasible to only sync the latest of each backup rather than 
the entire pool?

To elaborate, on Saturdays we run an rsync of the entire cpool to another 
server to provide disaster recovery options. Is it possible/reasonable to just 
copy the data from the night before? Or, with de-duplication and compression, 
would we really save much space/transfer time? If so, what is the best way to 
grab just one night's worth of backups while still preserving a full recovery?

Just curious if someone is already doing this and how you sorted it out.

Thanks!

Re: [BackupPC-users] DumpPreUserCmd logging stopped after updating to 4.3.1

2019-09-30 Thread Mike Hughes

Yeah, this is indeed still a problem for me. My DumpPreUserCmd needs to
preserve the logs. The problem is that if/when that cmd fails, the exit
status is checked and it registers a failure. Thus, the main backup is
aborted. With no main backup to process, there is no xfer log file
saved and the output of DumpPreUserCmd is irrecoverable. This makes it
very hard to troubleshoot a problem with no log output.

@CraigBarratt, Please consider reversing/revising this update!

Re: [BackupPC-users] home directory empty

2019-09-30 Thread Mike Hughes

This behavior has not changed over the years. You've found that the
/home folder exists on a separate partition than /. What is the value
of RsyncShareName? If it's just the default of "/", then that's the
only partition which will be examined by rsync and no other partitions
will be considered. This is because of the default flag --one-file-
system. Again, it's up to you if you want to target the /home partition
directly (by adding it to the RsyncShareName list), or capture all
filesystems by excluding that default rsync flag.

The question about which overrides what in the include/exclude lists
doesn't come into play unless you're actually scanning the /home partit
ion. See the docs for specifics regarding that once you get your
partition to scan.

Hope this helps!

No, that is the default setting in BPC. So if your /home is on a separate

The "--one-file-system" is listed in 'RsyncArgs'?

Have you verified that the systems which are not working as expected
don't have separate partitions for /home?

[BackupPC-users] new client won't back up

2019-09-18 Thread Mike Hughes

Hi BackupPC users,

I added a new host and it is encountering thousands of errors and won't
finish a backup. Instead it is dumping errors such as: 
file has vanished: "/etc/iscsi/initiatorname.iscsi"
rsync_bpc: fstat ... No such file or directory (2)
rsync_bpc: stat ... No such file or directory (2)
rsync_bpc: symlink ... failed: File exists (17)

More from the log is available here:
https://pastebin.com/rgeezxfi

This occurred once before with a different host and I don't believe I
ever solved it. I'm thinking of deleting the host from the backup
server and starting over unless anyone has a better solution.

Thanks!
Mike

Re: [BackupPC-users] BackupPC_dump stalls with SIGTTOU on Windows client using rsync

2019-09-06 Thread Mike Hughes

This seems like a dumb problem to have but I'm struggling to figure out how to 
tell BackupPC to ssh into the cygwin client as a local user.

The backuppc account was created locally on the machine to be backed up, thus 
it does not exist in AD. I am able to log in using other AD accounts with no 
problem using the format:
ssh username@my-host

I can connect to this local account if I prepend the hostname in uppercase with 
a plus(+) sign, like this:
ssh MY-HOST+backuppc@my-host

but cannot get BackupPC to log in to this local account. I've tried prepending 
the above to RsyncSshArgs:
$sshPath -l MY-HOST+backuppc

but without success. The logs indicate that it tried to use:
/usr/bin/ssh\ -l\ MY-HOST+backuppc@my-host

I've tried escaping the + but then I get:
/usr/bin/ssh\ -l\ MY-HOST\\+backuppc@my-host

Thanks for the responses gents. I see the error now (not sure if it was staring

I was testing ssh using a special definition on the command line:

but didn't provide those details to the client. Is there something in cygwin's 
sshd config file I can set to make it use local accounts by default?
Or do I need to find the correct syntax in BackupPC to indicate the local 
account on the RsyncSshArgs line?

Hopefully I'll get this sorted soon and share the fix.

Re: [BackupPC-users] DumpPreUserCmd logging stopped after updating to 4.3.1

2019-08-28 Thread Mike Hughes

Following up on this, I just realized that the output from DumpPreUserCmd is 
being stored under the XferLOG and the errors logs. If I open the backup's 
primary log file it only shows the rsync activity, but all my dumpPreUserCmd 
output is still being written to the detailed log files. I still need to 
confirm that the backup will hard-fail on an error from my user cmd, which is 
required for me to be aware that a database or table dump was not successful.

This line tells us that your shell (sh) is trying to run the command:

Re: [BackupPC-users] IO error encountered -- skipping file deletion

2018-12-17 Thread Mike Hughes

Hi Daniel,

It sounds like the exclusion rules aren’t working as you expect. If they were I 
don’t think you’d see the errors even if the pool files had a problem since 
they’d never be compared. I ran into problems when I set up mine too. If I 
recall my confusion was around identifying the share name in the exclusion 
rule. I often use an asterisk to cover all shares so my exclusion statements 
look like this:

$Conf{BackupFilesExclude} = {
  '*' => [
'/ var/log/pve/tasks’,
'/ var/log/pve/etc’
  ]
};

Hope this helps!

Subject: [BackupPC-users] IO error encountered -- skipping file deletion


Hi.



I'm running BackupPC v4.3.0 on CentOS 7 for a bit more than 200 hosts. Most are 
using rsync Xfer method and are working fine.

But for two of them, I started last week to have respectively 3 and 6 xfer 
errors, on every new backup (no matter if I start a new complete, or incr 
backup)

Eg:



[ 57 lignes sautées ]

file has vanished: 
"/var/log/pve/tasks/6/UPID:pve3:597E:01554D97:5C0C5076:vzdump::root@pam:"

IO error encountered -- skipping file deletion

[ 82 lignes sautées ]

rsync_bpc: fstat 
"/var/log/pve/tasks/6/UPID:pve3:597E:01554D97:5C0C5076:vzdump::root@pam:" 
failed: No such file or directory (2)

[ 5 lignes sautées ]

rsync_bpc: fstat 
"/var/log/pve/tasks/E/UPID:pve3:5875:0162BE48:5C0C72DE:aptupdate::root@pam:"
 failed: No such file or directory (2)

I did had those files when the first backup reporting the errors ran. But they 
do not even exist anymore now. I've also tried to exclude the impacted 
directories, but the issue remains. So I guess there's something wrong on the 
pool. How can I check this ? And how can I fix it so it doesn't report Xfer 
errors anymore ?



Regards,

Daniel

Re: [BackupPC-users] Large files with small changes

2018-11-20 Thread Mike Hughes

Hi Steve,

It looks like they are stored using reverse deltas. Maybe you’ve already seen 
this from the V4.0 documentation:

  *   Backups are stored as "reverse deltas" - the most recent backup is always 
filled and older backups are reconstituted by merging all the deltas starting 
with the nearest future filled backup and working backwards.
This is the opposite of V3 where incrementals are stored as "forward deltas" to 
a prior backup (typically the last full backup or prior lower-level incremental 
backup, or the last full in the case of rsync).

  *   Since the most recent backup is filled, viewing/restoring that backup 
(which is the most common backup used) doesn't require merging any deltas from 
other backups.
  *   The concepts of incr/full backups and unfilled/filled storage are 
decoupled. The most recent backup is always filled. By default, for the 
remaining backups, full backups are filled and incremental backups are 
unfilled, but that is configurable.
Additionally these tips might help apply deltas to the files and reduce 
transfer bandwidth:

MySQL dump has an option  ‘--order-by-primary’ which sorts before/while dumping 
the database. Useful if you’re trying to limit the amount to be rsync’ed. 
You’ll need to evaluate the usefulness of this based on db design.

If you’re compressing your database look into the “--rsyncable” option 
available in the package pigz.

Subject: [BackupPC-users] Large files with small changes


I think some backup programs are able to store just the changes ("deltas") in a 
file when making incrementals. Am I right in thinking that BackupPC doesn't do 
this, and would instead store the whole of each changed file as separate 
entries in the pool?

Reason for asking is that I want to implement a backup strategy for databases, 
which is likely to involve multi-megabyte SQL files that differ only slightly 
from day to day. I'm trying to decide how best to handle them.

that makes perfect sense. That wording has caught me off-guard too. I think a

What is your setting for $Conf{BackupPCNightlyPeriod}?  The default is 1, but 
if it's set to something larger then it will take that number of days/nights 
for the entire pool to be traversed.

It does appear that some of the files are getting deleted - yesterday afternoon 
it deleted 242189 files (although the total size wasn't very large), and 
2149846 remain.  That could be reasonable after 6 days with 
$Conf{BackupPCNightlyPeriod} set to 16.

I'm concerned I may have created a race-condition when I asked the system to 
delete the individual backups then removed the client and pc folders before it

the full 306GB in pool is solely for this host. Is it safe to delete the

I'm concerned I may have created a race-condition when I asked the system to 
delete the individual backups then removed the client and pc folders before it 
could complete. This was the only host set to not use compression and I believe 
the full 306GB in pool is solely for this host. Is it safe to delete the 
contents of pool?

Re: [BackupPC-users] syncing local and cloud backups

2018-10-14 Thread Mike Hughes

Thanks for the information Ed. I figured I could leave the '-z' off the rsync 
command.

Regarding parallel backups: I see your point of chains exposing the potential 
to nuke all backups but aren't you increasing the exposure of your production 
system X2 by giving another backup process access to it? Just curious on your 
thoughts on that since you seem to have been down this road.

I can answer the rsync compression question.  no.  Running gzip'd data through 
gzip is a waste of CPU power.  Depending on your link and CPU speed it may even 
slow down your ability to transfer data.

As for the recovery from an rsync'd backup...
If your /etc/BackupPC and /var/lib/BackupPC directories are already symlinks to 
other locations, you can easily shut down BackupPC, swap links, and start it 
up.  So long as both systems are running the same version, it should come up 
cleanly.

I gave up backing up the backup server though.  If you want proper redundancy 
you run backups in parallel, not in a chain.  If one backup server has access 
to the other backup server, then it has the potential (if compromised) to 
destroy all of your backups and originals from one location.  Redundant backups 
should live in separate private enclaves.

Another related question: Does it make sense to use rsync's compression when 
transferring cpool? If that data is already compressed, am I gaining much by 
having rsync try to compress it again?

Cool, thanks for the idea Craig. So that will provide a backup of the entire 
cpool and associated metadata necessary to rebuild hosts in the event of a site 
loss, but what would that process look like?

Say I have the entire ‘/etc/BackupPC’ folder rsynced to an offsite disk. What 
would the recovery process look like? From what I’m thinking I’d have to rsync 
the entire folder back to the destination site, do a fresh install of BackupPC 
and associate it with this new folder. Is that about right? Would there not be 
a method to extract an important bit of data from the cpool without performing 
an entire site restore? I’m considering the situation where I have data of

Re: [BackupPC-users] BackupPC 4.2.1 apparently in an infinite loop.

2018-09-16 Thread Mike Hughes

Michael,

Condescending and belittling treatment of others in this list is not the norm. 
Your personal attacks are unwarranted and unhelpful.


Since you reached out and asked for help in relating to others I will share 
with you this piece from Dr. Phil Agre which helped me immensely when I was 
learning the ropes at the helpdesk and I still refer to it regularly to help 
keep me on track:


"How to help someone use a computer.


Computer people are generally fine human beings, but nonetheless they do a lot 
of inadvertent harm in the ways they "help" other people with their computer 
problems. Now that we're trying to get everyone on the net, I thought it might 
be helpful to write down everything I've been taught about helping people use 
computers.

First you have to tell yourself some things:

  1.  Nobody is born knowing this stuff.
  2.  You've forgotten what it's like to be a 
beginner.
  3.  If it's not obvious to them, it's not obvious.
  4.  A computer is a means to an end. The person you're helping probably cares 
mostly about the end. This is reasonable.

Their knowledge of the computer is grounded in what they can do and see -- 
"when I do this, it does that". They need to develop a deeper understanding, of 
course, but this can only happen slowly, and not through abstract theory but 
through the real, concrete situations they encounter in their work.

By the time they ask you for help, they've probably tried several different 
things. As a result, their computer might be in a strange state. This is 
natural.

The best way to learn is through apprenticeship -- that is, by doing some real 
task together with someone who has skills that you don't have.

Your primary goal is not to solve their problem. Your primary goal is to help 
them become one notch more capable of solving their problem on their own. So 
it's okay if they take notes.

Most user interfaces are terrible. When people make mistakes it's usually the 
fault of the interface. You've forgotten how many ways you've learned to adapt 
to bad interfaces. You've forgotten how many things you once assumed that the 
interface would be able to do for you.

Knowledge lives in communities, not individuals. A computer user who's not part 
of a community of computer users is going to have a harder time of it than one 
who is.

Having convinced yourself of these things, you are more likely to follow some 
important rules:

  *   Don't take the keyboard. Let them do all the typing, even if it's slower 
that way, and even if you have to point them to each and every key they need to 
type. That's the only way they're going to learn from the interaction.
  *   Find out what they're really trying to do. Is there another way to go 
about it?
  *   Attend to the symbolism of the interaction. Try to squat down so your 
eyes are just below the level of theirs. When they're looking at the computer, 
look at the computer. When they're looking at you, look back at them.
  *   Explain your thinking. Don't make it mysterious. If something is true, 
show them how they can see it's true. When you don't know, say "I don't know".  
When you're guessing, say "let's try ... because ...". Resist the temptation to 
appear all-knowing. Help them learn to think like you.
  *   Be aware of how abstract your language is. For example, "Get into the 
editor" is abstract and "press this key" is concrete. Don't say anything unless 
you intend for them to understand it. Keep adjusting your language downward 
towards concrete units until they start to get it, then slowly adjust back up 
towards greater abstraction so long as they're following you. When formulating 
a take-home lesson ("when it does this and that, you should check 
such-and-such"), check once again that you're using language of the right 
degree of abstraction for this user right now.
  *   Whenever they start to blame themselves, blame the computer, no matter 
how many times it takes, in a calm, authoritative tone of voice. If you need to 
show off, show off your ability to criticize the bad interface. When they get 
nailed by a false assumption about the computer's behavior, tell them their 
assumption was reasonable. Tell *yourself* that it was reasonable.
  *   Formulate a take-home lesson.
  *   Take a long-term view. Who do users in this community get help from? If 
you focus on building that person's skills, the skills will diffuse outward to 
everyone else.
  *   Never do something for someone that they are capable of doing for 
themselves.

* Don't say "it's in the manual". (You probably knew that.)"


Source: http://polaris.gseis.ucla.edu/pagre/how-to-help.html

This is just a basic framework to keep in mind when helping others learn 
something that you already know. Adapt it as necessary to fit the situation.

I hope this helps.

Sincerely,
Mike

Re: [BackupPC-users] ver 4.x split using ssd and hdd storage - size requirements?

2018-08-28 Thread Mike Hughes

The partition where the "pc" folder lives needs to be larger than the size of 
your largest backup target. It will grow to the size of whatever is being 
backed up at that moment. If you have simultaneous backups, I believe it could 
grow larger than your largest backup target.

Here is how I came to that conclusion: I have been monitoring changes in the 
size of the "pc" folder every second to learn how to anticipate disk usage and 
build a better server. These are the highs and lows experienced over a typical 
evening:

01:00:29   0G
01:04:30   2G
01:07:57   1G
01:11:36   6G
01:22:16   0G
01:27:13   1G
01:31:41   0G
01:53:22   25G
02:12:39   0G
02:31:10   23G
03:05:59   0G

This was measured while backing up seven RHEL web/mysql servers on a LAN; some 
with large database dumps. All backups triggered at 1:00a and most completed in 
20 minutes. The other two servers performed full backups and took about two 
hours each, and must be responsible for the 20GB spikes. I can confirm by 
looking at the "File Size/Count Reuse Summary" table that their sizes are 
20-25GB. Add to that the potential of simultaneous runs so be sure your "pc" 
folder is on a large enough partition.

That was a really good idea and I think you nailed it. Here's a one-second 
update on used space for the /var partition during an incremental backup:

So it's definitely requiring more storage than I expected. I love the idea of 
using an SSD to increase performance but I need to better understand the growth 
potential during backups, especially during simultaneous backups.

[BackupPC-users] ver 4.x split using ssd and hdd storage - size requirements?

2018-08-24 Thread Mike Hughes

I think I've discovered a new level of failure. It started off with these 
errors when attempting to rsync larger files:

rsync_bpc: failed to open 
"/home/localuser/mysql/hostname-srv-sql.our_database.sql", continuing: No space 
left on device (28)
rsync_bpc: mkstemp 
"/home/localuser/mysql/.hostname-srv-sql.our_database.sql.00" failed: No 
space left on device (28)

Now all backups are failing and I see these in the Xfer Error logs:

BackupPC_refCountUpdate: can't write new pool count file 
/var/lib/BackupPC//pc/hostname/22/refCnt/poolCntNew.1.a8
BackupPC_refCountUpdate: given errors, redoing host hostname #22 with fsck 
(reset errorCnt to 0)
bpc_poolRefFileWrite: can't open/create pool delta file name 
/var/lib/BackupPC//pc/hostname/22/refCnt/tpoolCntDelta_1_-1_0_70674 (errno 28)
bpc_poolRefRequestFsck: can't open/create fsck request file 
/var/lib/BackupPC//pc/hostname/22/refCnt/needFsck70674 (errno 28)
Can't write new host pool count file 
/var/lib/BackupPC//pc/hostname/refCnt/poolCntNew.1.02

My guess is that the /var/lib/BackupPC/pc partition is the problem. I took 
advice from some rando on the interwebs [1] to put the pc folder on an ssd but 
perhaps it needs more headroom than suggested:

"... Split the storage up on SSD for the pc folder and something more cost 
efficient for cpool such as SMR drives. ...The pc folder in version 4 
essentially only contains the directory structures and references of files that 
they should contain, so it stays very small. However, it is often read from and 
speeds things up remarkably when it is served fast. Much more so than speeding 
up the cpool."

The "pc" folder lives in "/var/lib/BackupPC/pc" on a local ssd with 5GB 
overhead available. The storage pools live on a platter w/70+GB free. Am I 
short-changing the "pc" folder? Does it need to grow significantly during 
backup runs? If so, how much space is suggested?

Unfortunately my monitoring software (NewRelic Infrastructure) does not provide 
much granularity and has previously hidden similar spikes in usage so I don't 
trust its reports, which does not show any capacity violations.

Thank you!

[BackupPC-users] XFS journal location; pc folder on smaller SSD; rsync --inplace question

2018-08-22 Thread Mike Hughes

I'm seeing out-of-storage errors from rsync_bpc when transferring large (4 GB) 
files:

rsync_bpc: failed to open 
"/home/localuser/mysql/hostname-srv-sql.our_database.sql", continuing: No space 
left on device (28)

The volume supporting the 'pc' folder has 6 GB free and lives an SSD under 
/var/lib/BackupPC whereas the pool folders are linked to a traditional hard 
disk with 78 GB free. The backup pool lives on a 100GB platter with a 
LUKS-encrypted LVM hosting an XFS filesystem. The 'pc' folder resides on the 
operating system's SSD:

# ls -lht /var/lib/BackupPC
total 4.0K
drwxr-x---. 9 backuppc backuppc 4.0K Aug 20 12:06 pc

lrwxrwxrwx. 1 backuppc backuppc   34 Aug 14 14:35 cpool ->

So which system is it claiming is out of space? Full Xfer error log and other

You are probably already aware of this, but an SSD’s life expectancy is based 
on the number of writes.  Therefore, utilizing an SSD as the cache drive and 
the OS drive might require some additional considerations over the long haul.

Thanks,

Interesting discussion. I also put the xfs journal on SSD using:
'mkfs.xfs -l size=64m,logdev=/dev/sdb1 /dev/mapper/luks'
where the luks-encrypted partition is in an LVM on platters and sdb1 is an 
Azure "resource" temporary storage.

Regarding the location of the "pc" folder... I think I need to re-visit that 
since I created a symlink from /var/lib/BackupPC and moved the entire contents 
of that folder to my platters. It sounds like I need to undo that to keep the 
"pc" folder on the SSD. Would a better move be to create a symlink just to the 
"cpool" folder? ie:
ln -s /mnt/backup-volume/BackupPC/cpool /var/lib/BackupPC/cpool
and leave "pool" and "pc" on the SSD with the operating system?

Transitioning from BPC 3.x to 4.x there seem to be some syntactic changes 
regarding rsync & ssh commands. I was able to follow documentation that I think 
lived on SourceForge where it was suggested to configure a non-root account for 
ssh’ing and running rsync under sudo. After some experimentation (and as I 
recall some frustration around “$argList” vs “$argList+”) I came up with the 
following which worked great in version 3.3:

RsyncClientPath: --> /usr/bin/rsync
RsyncClientCmd: --> $sshPath -q -x -l backuppc $host sudo $rsyncPath $argList+
RsyncClientRestoreCmd: --> $sshPath -q -x -l backuppc $host sudo $rsyncPath 
$argList+

I think the only change I made to Rsync[Restore]Args was to add 
--checksum-seed=32761

Now in ver 4.2.1 the variables have changed. This is what I’m able to make work 
so far:

RsyncBackupPCPath: --> /usr/bin/rsync_bpc
RsyncClientPath: --> sudo /usr/bin/rsync
RsyncSshArgs: --> -e
--> $sshPath -l backuppc

However something is definitely off because the backup is incomplete. Many 
files and folders are missing. The most obvious is /home folder:
[cid:image001.jpg@01D432E5.6CA52990]
[caption – the home folder is empty – contains zero users!]

This is the only reference to “home” in my exclusion list:

'/home/windows',

because I want to skip a folder named /home/windows.

Any help appreciated. Since I saw previous requests for this info here is my 
redacted XferErr from the latest run. I also tried removing --protect-args from 
RsyncArgs and added charset = utf-8 to the client’s /etc/rsyncd.conf and 
restarted the service):

Hi BackupPC users,

Just curious if anyone else has made the changes necessary to use a non-root 
user account in the 4.X versions and run into any difficulty with incomplete 
backups?

Thank you!

LOL! I do not want to build everything from source! I’m just following the 
documentation as I’ve been able to find it. You suggested a script which 
installs on Debian-based systems so I’m trying to follow those steps on CentOS.
I’ve been running V 3.3.1 from EPEL for a couple years and am ready to move to

Mike,

First, I would strongly recommend using the rsync-bpc 3.0.9 branch.  The head 
is based on rsync 3.1.2 but it hasn't seen as much testing and hasn't been 
released.  You should do a "git checkout 3.0.9" before running ./configure, eg:

git clone https://github.com/backuppc/rsync-bpc.git
cd rsync-bpc
git checkout 3.0.9
./configure
make

Second, why do you actually want to build everything from source?

I don't have access to a Centos 7 box to test building.  However, I suspect 
you'll need to install a libacl-devel package (or similar) to get the C headers 
etc.  Many linux libraries have two packages - the runtime library, and another 
(generally with "devel" in the name) for compiling and linking code.

Mike,

You have to build and install backuppc-xs first.  Also, makeDist needs a 
--version argument.

The wiki has an example 
script<https://github.com/backuppc/backuppc/wiki/Installing-BackupPC-4-from-git-on-Ubuntu-Xenial-16.04-LTS>
 for building from git.

Thanks for the reply. I’m building on CentOS7 so the example is partly useful 
but there are several changes. Here are some basic steps in case someone else 
attempts this:
yum install git build-essential perl-devel perl-CPAN perl-CGI gcc httpd mod_ssl 
glusterfs-client
cpan [accept all defaults]
install Test::More
quit
reboot (might not be necessary)
git clone https://github.com/backuppc/backuppc.git
git clone https://github.com/backuppc/backuppc-xs.git
git clone https://github.com/backuppc/rsync-bpc.git
cd backuppc-xs/
perl Makefile.PL
make
make test
make install

cd ../rsync-bpc
./configure
make

…and this is where it fails with:
lib/sysacls.c:2761:2: error: #error No ACL functions defined for this platform!
#error No ACL functions defined for this platform!
  ^
make: *** [lib/sysacls.o] Error 1

I’m not sure if this is helpful but acl’s (Access Control Lists) are supported 
on this system:

[Cent-7:root@hostname rsync-bpc]# yum install acl
Package acl-2.2.51-14.el7.x86_64 already installed and latest version
Nothing to do

[Cent-7:root@hostname rsync-bpc]# cat /boot/config-3.10.0-862.9.1.el7.x86_64 | 
grep _ACL
CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_XFS_POSIX_ACL=y
CONFIG_BTRFS_FS_POSIX_ACL=y
CONFIG_FS_POSIX_ACL=y
CONFIG_GENERIC_ACL=y
CONFIG_TMPFS_POSIX_ACL=y
CONFIG_NFS_V3_ACL=y
CONFIG_NFSD_V2_ACL=y
CONFIG_NFSD_V3_ACL=y
CONFIG_NFS_ACL_SUPPORT=m
CONFIG_CEPH_FS_POSIX_ACL=y
CONFIG_CIFS_ACL=y

Am I making a mistake in installing the current version? Perhaps I’d have 
better results installing the version identified in the Debian-based script?
Thank you!

Mike,

You have to build and install backuppc-xs first.  Also, makeDist needs a 
--version argument.

The wiki has an example 
script<https://github.com/backuppc/backuppc/wiki/Installing-BackupPC-4-from-git-on-Ubuntu-Xenial-16.04-LTS>
 for building from git.

Not sure why I’d need to generate a tarball but when I run makeDist I get:
