[BackupPC-users] Find pc files from pool file name (checksum)

[Kenneth Porter]

Is there a script that can iterate over all pc files to find the ones 
that match a pool file? I've found some corrupt pool files and am trying 
to figure out my exposure. What does BPC do when it encounters such a 
bad file (when its checksum doesn't match its name) during the nightly scan?


Also, how does BPC know that a pool file is no longer in use? Is there a 
count of how many pc files are using it?

Not sure why you would be blaming backuppc for that.


Is there a utility that can systematically check all the files? Since 
the filenames are checksums.


Finally, you should backup your backups. I run two independent

versions of backuppc in my home situation with one running on a RPi4.


This would make a great turn-key product. Or an app for a NAS. Small

Re: [BackupPC-users] restoring pool

[Kenneth Porter]

In the future, I recommend putting the config on the external drive and 
mounting it to /etc/BackupPC.


I'd also recommend copying/tarring /etc/httpd or /etc/nginx (depending 
on which web server you use) to the external drive. That lets you bring 
up BackupPC quickly on a replacement server after a disaster.

First off I've never run BackupPC on anything except bare metal.  As
far as I can remember I haven't even tried to run it in a VM let alone

BackupPC itself.  By using this form of installation you might be
making it easy to install BackupPC if it works, but I don't think it's
necessarily going to make it easy to troubleshoot things if it doesn't.
Looking at 'Dockerfile' in .../adferrand/docker-backuppc.git makes me
ask more questions than it answers for me. 


I concur with the rest of your analysis and questions. But I can see the 
value of a Docker image. It's no worse than running on some unusual 
Linux distro. Containers and VMs let an app isolate itself from the 
package choices of the host OS, relying solely on the kernel. It's why 
Snap is making inroads against traditional RPM and dpkg packaging 
systems. The older systems are fine for keeping the underlying system 
stable, but not so good for apps that use bleeding-edge libraries. The 
new container-based packaging helps separate responsibilities between OS 
libraries and app libraries.


Of course, the end-user/administrator then has to figure out where to 
send problem reports: To the distro/container maintainer or the app 
developer. This does look like a packaging issue and not an issue with 
the app. So I'd recommend opening an issue on GitHub against the 
container project.

Re: [BackupPC-users] Why not use Backuppc to backup server systems?

[Kenneth Porter]

When backing up the backup server, either mount /etc/BackupPC from the 
backup media (and back that up to another place) or keep a tarball with 
the latest settings, so you can easily load the media on another server 
to recreate the backup server.

to look at the upstream changes. I found that upstream's version (3.2.7) is

[BackupPC-users] Backup strategy for rarely-connected clients

[Kenneth Porter]

My company has a laptop that spends most of its time on a shelf, not in 
use. So I'm constantly seeing a daily BackupPC alert in my email that 
the machine hasn't been backed up recently.


How do others deal with this situation, with machines that are rarely 
connected to the LAN for backup?


An additional problem is that the machine might only be connected for a 
short period, so the server might miss that window and fail to back it 
in the short period it's connected, as it's busy with other backups.

[BackupPC-users] Slow web page loading of admin pages

[Kenneth Porter]

I've never had a problem loading the website before to administer my three 
BPC 4 servers. It's been reasonably fast, even with a slower server.


This week I set up access for a user with a failed computer so that he can 
retrieve files while his PC is being repaired.


Two PCs at the office that are much newer than mine are very slow at 
loading the web pages. The upper left navigation pane loads immediately, 
but it can be minutes before the rest of the page renders. We tried both 
Edge and Chrome on Win10 x64. If we hit the back button and forward button, 
the whole page loads instantly. This also happens as we try to navigate 
down a backup's directory tree. Back and forward will cause the new 
directory to open, but it won't open the subtree on the first click. I went 
to my office and opened the same pages and they open instantly.


What should I look at to diagnose this? Maybe something in the Chrome debug 
console?

Re: [BackupPC-users] Tar causing problems with removable drive on localhost

[Kenneth Porter]

I haven't found a good explanation of how the /media mount system works. 
It seems that mechanism changes frequently.


For my CentOS 7 system with a USB external drive for backups, I use 
systemd mount units to mount the drive when anything tries to touch 
/var/lib/BackupPC. I'd suggest doing something similar to hold your 
video library. Find a suitable "permanent" mount point (like /opt/Videos 
or /mnt/Videos) and create a pair of systemd unit files in 
/etc/systemd/system.


Here's the files I use for my backup drive. The file names are important 
and should reflect where you plan to mount. Only enable the .automount 
one. It starts the .mount file when the target directory is touched.


The mount options here are from when I needed to upgrade the drive to a 
larger size and the copy process was extremely slow.

You can spend hours trawling through logs, but mostly I'd search in

in that order. 


A trick I've learned is to issue "ls -lt /var/log | head -20". This will 
list the 20 log files most recently written to. Alas, it doesn't find 
journald stuff, and it doesn't look in subdirectories, so you need to do

Thanks, that's perfect. I'm backing up the backup server to itself via

It looks like the pool grew only very slightly as a result.


(The idea is that this server will become the new server when the old one

all the files to their final locations when we switch. Switching hardware

The main problem is that "yesterday's" backup might be off-site for

rsync over the network should use compression. If you're doing it inside 
ssh, then use ssh's compression, which is more reliable. The run of 
nulls will be compressed down to a count and one null. Their transfer

[BackupPC-users] rsync open-noatime option

[Kenneth Porter]

Is anyone using the rsync/rsyncd method with the open-noatime option to 
avoid unnecessary metadata writes when comparing files?


I'm disabling atime on all my Linux partitions and wondering if that option 
has any effect on Cygwin rsyncd running on my Windows 10 clients.


It does look like NTFS has the file property, and Win10 has some registry 
settings for controlling when it's updated:

Not really. I've just written some network code and lots of

The Android side of the connection looks to be stuck in a similar

What's the source of the rsync on Android? What versions are in use? 
Perhaps there's a version incompatibility with the one embedded in

This smells like a deadlock. This code is waiting for 2 bytes in the

Once it stalls but before the timeout, run ps and lsof to see what files

The incremental nature of BackupPC should address the ransomware issue,

Mea culpa. This time I saw the bold text, so this list DOES show bold. 
Just not in digests.



"$Conf{RsyncClientCmd} = '$sshPath -l backuppc *$host nice -n 19

so none of that line was executed, but because there are separate

host V4 was connecting to the client without the "nice -n 19 
/usr/bin/sudo" portion, thus not able to access any of the file data. 
Once I realized this I knew it was just a matter of rearranging the 
arguments to fit the new format which I succeeded in doing except for 
"nice -n 19". 


So the issue is the missing sudo, not the call to nice.

Although I hadn't inspected the config to know that nice was being used 
in V4. I'd love to see a similar thing for rsyncd on Windows that 
reduces I/O priority to reduce the impact on backups done during the 
day. I have users who insist on turning their machines off at night so 
the only time I can get a backup is while they're using the machine. 
I've been using System Explorer to lower the priority on the rsync process.

I saw a new release in my daily yum update check on CentOS 7 and wondered 
what changed. It turns out to be a change to the systemd invocations in the

to update. Here's the recent RPM changelog:

Re: [BackupPC-users] Lost config.pl file during full backup

[Kenneth Porter]

I highly recommend installing etckeeper. It puts all of /etc under 
revision control. I use CentOS which is based on yum/dnf/rpm and it will 
perform an auto-commit of changed files before updating. I disable that 
feature so that yum won't update until I manually commit any outstanding 
configuration changes, to make sure they get a proper change comment. 
etckeeper uses git by default but you can use another revision control 
system if you prefer. A minimal knowledge of git is handy for doing 
manual commits and inspecting your change history.


Your distribution should include an etckeeper package.

ext4 stores owner and group id numbers, so you need to do a "chown -R 
backuppc.backuppc /var/lib/BackupPC" when it's mounted to set the uid 
and gid. Alas, it looks like the UID and GID for backuppc aren't 
registered so they get dynamically allocated when the package is 
installed. They'll be different on every system. So one might need to do 
the chown as part of a startup script if the drive gets shared among 
several servers.


Tip:

Mount the drive's root to /mnt/BackupPC, create subfolders /backuppc/etc 
and /backuppc/BackupPC, then do a bind mount of those folders to 
/etc/BackupPC and /var/lib/BackupPC. That way you'll keep the 
configuration on the drive with the data. It makes a bare-metal recovery 
easier if the server dies.

clients has nice color bands in the table indicating success with light

servers have only white backgrounds for all clients. Looking closer, I

while the big server has "done" in that column. Why don't the small servers

Presentation would be interesting. Most useful would be a treemap of the

many clients shared it. One could optionally weight a file's size by how 
many clients shared it.


(Is there a way to add links to external facilities in BackupPC? I 
currently have a separate page with the link to the cygwin rsyncd package

Of course, if you "welcome" such a plugin, you are more than
"welcome" to write one as this is an open source project...

I just don't see it happening by itself as the dev team is small (mostly
Craig) and focused on core stability and functionality.


Oh, I'm quite aware it would be SMOP, hence the suggestion that it be a 3rd

It sounds like you could go old-school (pre-DNS!) and use a shared hosts 
file. Just rsync it from the hosts file master at regular intervals.

The hostname should then resolve to the write IP address assuming you

If the hosts support mDNS (and Windows does), use hostname.local. You might 
need to install the Avahi package on your BackupPC server to use mDNS. This 
eliminates the need to set up a DNS server for your LAN.

[BackupPC-users] systemd mount point dependencies

[Kenneth Porter]

I'm rigging up a new BackupPC server to use an external USB drive and I 
wanted to get systemd to automount the drive when the service is started. I 
just found this nice article on how to do that:




My use case is slightly complicated because I want to mount both 
/etc/BackupPC and /var/lib/BackupPC from the external drive using bind 
mounts, so I'll actually need three mount unit files, for the physical 
mount and the two bind mounts, plus a drop-in to modify the BackupPC 
service unit file.

Top-posting is for email systems where people continually join a thread and 
there's no central archive to consult to see what has gone on before. It's 
suitable for business correspondence.


Mailing lists and newsgroups are different: They have archives where new 
list members can look to see the history of a thread. The only thing you 
should quote in your reply is enough context to make it clear what in the 
previous post you're replying to. Interleave your reply with the context 
hints you quote. But chop out everything else. We've already read it. We 
don't need another copy.


I filter mailing list messages to a seperate folder for each list and my 
mail clients know how to thread a discussion into a tree structure. It 
keeps my inbox uncluttered and I can easily understand the structure of a 
converstation.

My suspicion is that the BackupPC service is trying to start before the 
credentials server is up. This is where you need systemd, to make sure 
the order of startup is obeyed, and to allow dynamic conditions such as 
a slow-starting credentials server. The default systemd unit file for 
BackupPC doesn't check for this. You need to extend it to add a 
dependency on connectivity to the credentials server.

I'm thinking that "rsync $host::" would be a good substitute for an

disk cache and verifies that the service, not the host, is up and 
accessible.


I set up a new Win10 client the other day and forgot to open the 
firewall to ping when I opened it to rsync.exe. I mostly work from home 
so fixing that means I have to coordinate with the user to meet him when 
he's at the office and not busy using the host. It's just easier to 
change the ping setting. And, since Windows defaults to disallowing 
ping, perhaps this change is a good choice for all Windows rsyncd clients.

A better solution would be a change to rsyncd to monitor its filesystem and 
remember which files were touched since the last backup. Some filesystems 
have a "backdoor" like inotify that lets you get notified of files getting 
touched. rsyncd could log these and only consult this list, not the whole 
filesystem. You'd need some way to reset the list and force a full 
filesystem check.

The point is to observe any error messages during rsyncd startup that

you. You start it in the background, it finds something fatal and dies. 
And it's not logging it so you can't see what's killing it. Run the

Once you get that working, we can move on to making it start from

the rsyncd process.)

On Fedora and CentOS 7, you should be starting the daemon with systemd, 
like this:


systemctl start rsyncd

To enable rsyncd to start when the system boots, enable the service (which 
puts it on the list of boot-time services):


systemctl enable rsyncd

Note that, in systemd, enabling a service doesn't immediately start it. It 
just adds it to the list of services to start on a reboot. Typically you 
test the service by starting it manually first with the start command. Once 
you have it working the way you want it, you enable it to make sure it runs 
after reboots.

Is rsyncd listening on the IPv6 interface? Or only the IPv4 interface? The

loopback.


Also, your test command is a push command. The arguments are source and

Test the connection with the regular command line rsync client. Just run

the modules available to back up.) You can also use "lsof -i" to see if 
anything is listening on the rsyncd port. Maybe rsyncd isn't running? 
Could you have a firewall rule blocking that port on the loopback

being used.

[BackupPC-users] Web access restrictions and IPv6

[Kenneth Porter]

In case anyone else has this problem

I suspect a Win10 update changed the way my web client (Chrome) accesses my 
Linux Apache server, favoring IPv6 over IPv4. I'd originally configured it 
to allow connections from my LAN's IPv4 prefix and all worked fine. This 
week (after a couple weeks of not checking) I found I couldn't connect. I 
traced it down to the connection coming from my link local IPv6 address. So 
I needed to add an extra Require stanza to my Apache config. If your 
error_log shows connections refused from addresses starting with fe80, 
you've run into this issue.

[BackupPC-users] rsyncd and selinux

[Kenneth Porter]

I just fought through dealing with errors in my backup due to attempting to 
back up sockets and wanted to share my solution.


Here's an example of the error message:

rsync: readlink_stat("/var/spool/postfix/private/tlsmgr" (in root)) failed: 
Permission denied (13)


(Postfix creates a directory full of sockets for all its processes, so I 
got quite a few errors in that directory.)


On CentOS 7 I found I needed this:

setsebool -P rsync_full_access 1

You may also need:

setsebool -P rsync_export_all_ro 1

I'd prefer to just enable read-only access but that doesn't allow the 
readlink_stat needed to back up a socket. (I don't see a man page for that. 
Is that API part of BackupPC or rsync?)

Like this:


su -s /bin/bash backuppc

/usr/share/BackupPC/bin/BackupPC_dump -v myserver


That will switch to the backuppc user and run the backup on the command 
line in verbose mode for the client "myserver". The backuppc user 
typically has no shell so you have to specify one on the su command line.

Try running it from the command line with -v (verbose) to see what's 
hanging it up.

What if you have TWO drives you want to mount to /var/lib/backuppc? With 
BackupPC 4, it's not unreasonable to swap your backup media every week 
to an offsite location.

Just create the skeleton directory structure in the external media and 
run restorecon once it's mounted.

Another thing one can do is move /etc/BackupPC to the external media and 
mount that directory over /etc/BackupPC so that your settings follow 
your media. This makes it easier to do bare-metal restores. Just install 
a minimal OS and BackupPC, then mount your backup drive and you've got 
all your settings ready to do the restore.

Re: [BackupPC-users] SELinux for v4.1.1

[Kenneth Porter]

After relabeling the external drive with restorecon (it ran overnight to 
label two million files), the web interface can now access the logs.

I haven't been able to use the mount options context= or defcontext=, as 
mount attempts with those set in fstab result in the drive not mounting. 
I've no idea what I'm doing wrong there. But I'll keep an eye on the 
drive to see if any new files are created without proper labels.

Re: [BackupPC-users] SELinux for v4.1.1

[Kenneth Porter]

tl;dr:

BackupPC users who want to enable SELinux should mount their backup media 
with either the context or defcontext options. (See links below for syntax.)

I think the default label is per-filesystem so the mount point prevents the 
files on the external drive from getting labeled properly. I found this 
article showing how to set the filesystem's default label. There's also an 
option context= for setting a label that overrides all label attributes on 
files within the filesystem. That may be be useful for drives that get 
moved between systems that don't have selinux or have different policies.

Further investigation shows that your package carries forth the selinux 
components from the Fedora package (which is the Right Thing), so I have 
those installed already.

I found through audit2why that the files in /var/lib/BackupPC (mounted from 
an external USB drive) are mislabeled as system_u:object_r:unlabeled_t:s0 
and should be labeled system_u:object_r:var_lib_t:s0. I'm running a 
recursive restorecon on the mount point to address that. But I need to find 
out why the backup script doesn't properly label these as it creates them. 
This should be done automatically and the app shouldn't need to do anything 
special. I'll investigate further.

The files in /var/log/BackupPC appear to be labeled correctly but the web 
CGI doesn't display them. This might be a side effect of the mislabeled 
/var/lib tree so I'll test again once the restorecon finishes.

[BackupPC-users] SELinux for v4.1.1

I found I also needed to install this yum plugin with a raw RPM command

It looks like the Fedora page for the package still lists Benjamin as 
maintainer, and I remember him doing that back in November when the 
original maintainer went MIA. Thanks for picking this up.

I look forward to seeing this. My C7 system has a blank USB drive ready to 
start mirroring my live BackupPC3 system with v4. I just want to install it 
as an RPM. (I've done some custom packaging myself and have debugged a lot 
of spec files. That COPR system looks pretty nice for that kind of work.)

[BackupPC-users] RPM for BackupPC 4

I know Benjamin Lefoul took over as packager for Fedora. Benjamin, is there 
an RPM coming soon for v4? I've got a CentOS 7 system suitable for testing 
it on.

Which installer are you using? I've been using WiX, which creates .msi 
files from XML descriptions. As with most software, it trades ease of 
use for power. It provides raw access to the system installer instead of 
a pretty GUI for very simple install scenarios.

http://wixtoolset.org/

  .msi files are databases with tables declaring where things go. The 
tables may contain binary blobs with embedded DLLs to take special 
actions beyond the ability of Windows' built-in installer. You can view 
and edit an MSI database using the Orca utility included with Visual 
Studio. Look for the orca.msi file after you install Visual Studio. On 
my system with multiple VS versions I find the installer here:

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\Orca.Msi
C:\Program Files (x86)\Windows Kits\8.0\bin\x86\Orca-x86_en-us.msi
