Re: [BackupPC-users] Problems Starting BackupPC

[Craig Barratt]

Michael is correct that BackupPC does use $Info->{pid} (which is read from
status.pl).  But it does check that that process exists before printing the
error message (using perl's kill(0, pid) that doesn't really send a signal,
but tells you whether the process is alive).  So I don't know why it claims
process 1289 is running; that would mean "kill(0, 1289)" returns 1
(success)...

Without finding the root cause, Michael's work-around is the right one -
remove the pid setting from status.pl.

Re: [BackupPC-users] error log for new host

[Craig Barratt]

Kris probably has the right explanation.  But it shouldn't matter -
multiple "/" in the middle of path have the same meaning as a single "/".
There are certain cases where a double leading '/' can have a special
meaning, although not on linux.

Paths with a trailing (or multiple trailing) "/" are usually equivalent to
no trailing "/", although programs can interpret a trailing "/" in
different ways (eg: rsync).

For more info, see the answer here

the point is you don't "allocate inodes" - if I'm not totally mistaken,
there's no syscall "reserve XXX inodes for me for later use". You open files
for writing - one at a time - allowing (or requiring) the system to create
the files in the process. There is a system limit to the number of files that
can be open at any one point in time (the reason probably being that kernel
memory needs to be statically reserved - some number of bytes for each), which,
as far as I can tell, is nowhere near the numbers you quoted. The number of
files a single process can open simultaneously is, I believe, lower yet. In
any case, to "allocate" millions of inodes, a process would have to open as
many files, closing them again to make space for new ones. The process would
have to keep track of all the names of those files (that is many million
multiplied with as many bytes as the file names would be long * bytes of
memory; quite noticeable on an average system) and then "quickly" delete
them again. My guess is that both creating and deleting those files would
take a considerable amount of time, depending on the filesystem (let's hope
they're at least not all in one directory ...). Above all, it would be quite
pointless.

I don't know what your NFS system is doing or showing, but I'd presume it is
in some way responsible for what you were seeing. How do you "set the maximum
number of inodes" for an NFS filesystem, and what do you mean by "pre-allocated
inodes"? Were you migrating a V3 pool from which some pool files have now
expired?

i haven't hit this upgrade yet, since i'm running Ubuntu LTS 16.04.  but
i have to say that from what i'm hearing, i'm not looking forward to
it.  i have multiple hosts with host-specific RsyncClientCmd and
RsyncRestoreCmd settings, sometimes to simply change the port number, but
at other times to provide a wrapper script which tries a couple of addresses
for the host before giving up.

if backuppc isn't going to handle the upgrade seamlessly, i hope there's
a more obvious warning than "do you want to take the maintainer's new
version?".  it should spell out that the upgrade will be a bit complicated,
and that perhaps it should be delayed until the user has enough time.

as i say, i haven't attempted this upgrade yet.  perhaps i'm worried
about nonexistent issues.  you just scared me a bit, is all.  ;-)

As far as I can tell, an automatic conversion is not always possible. For
simple cases, it's easy enough. Varying orders of ssh command line options
make things complicated. And in the general case, RsyncClientCmd could be
virtually *anything* that leads to a connection to something that emulates
an rsync protocol. I'm not sure RsyncSshArgs can be as flexible, or at least
that this can be achieved by an automated configuration translation.

Also, I believe configure.pl doesn't handle host configuration files, and I
would assume that doing so in postinst would violate policy, because host
configuration files don't belong to the package, do they?

Aside from that, there is no longer an RsyncClientRestoreCmd, so part of the
formerly possible configuration simply does not translate.

Finally, the configuration file may contain arbitrary Perl code for
determining the value of RsyncClientCmd (or anything else, for that matter),
defeating conversion as with the web configuration editor.

Thinking about it, for config.pl, simply including a new version would leave
it up to the user to resolve the differences between his local version and
the new version, wouldn't it?

Holger

Even the concept of the storage space used up "by one host" is difficult to
define. Due to pooling, a file found on N hosts in M locations during O backups
is only stored once - how much of the storage space is allocated to each host?
How much computing power do you want to put into finding that out? When doing
a new backup, do you want to disallow creation of a new reference to a file
already existing in the pool (i.e. requiring no new space), because the
storage space accounted to this host would exceed its quota? Do you want
quotas to apply before or after pooling and/or compression? Do you even really
want quotas, or are you just trying to prevent mistakes from filling up your
pool? (Actually, that might even be a neat feature request - abort a backup
if it exceeds $Conf{BackupMaxSize} (definable per host or even per share).)

Your usage case may (possibly) not have any content shared between hosts, but
the concept of BackupPC does, so any solution would have to work for the
general case.

And you don't get the benefit of pooling between the pools.

Re: [BackupPC-users] Problems Starting BackupPC

[Holger Parplies]

Hi,

I really don't know where to start on this one, and my reply is off-topic,
even if the original post wasn't, so sorry about that.

For the archives: don't "kill -9". Period.

"kill -9" means "I saw someone use this for a different problem, and I wanted
to try it, too. I don't really know what it does or why I am using it. I don't
really care whether things get better or worse, I'll just take my chances."

If you think you forgot your keys, what do you do? "kill -9" is the "break
down the door" variant. More sane approaches might be
- check your pockets to make sure you really don't have your keys with you
- knock on the door or ring the bell. Maybe someone is home.
- call a locksmith.

Of course, breaking down the door always works, whereas the other approaches
might not, so that's what you should start with, right?

I'll skip the details on why this was a bad idea in this instance.

Hope that helps someone.

Regards,
Holger

P.S.: Yes, it might ultimately turn out that you need to break down the door,
  but, in my experience, you usually don't break down a *random* door
  even then.

Hi,

Thank you for the explanations, even though I think I've understood 
about 10% of what you wrote ;-)
I understand it's not easy to implement each request any user can ask 
for. So don't worry.
I've started working on this vpn connection without knowing exactly what 
I could use it for, but I see that little by little, it will become more 
and more useful.
I'm still working on it and when I'll have better understood how it 
works, I'll re-read all these posts.

I'm using BackupPC 3.3.0 (got from the Web gui).
Yes this feature would be really great (at least for me !!).

sorry, really busy, two quick remarks:
Can't be too difficult to backport "this feature" (context = array argument
to ClientNameAlias possible) to 3.3.0. Supposing I find the time before
someone else does, I'd look at it ...


Thank you to all for your help. I'm still fighting with the vpn
connection. I'll tell you if I succeed (one day) to backup through
this f... vpn connection.
vpn + nice feature => king of the world.

You *can* use a VPN locally, too. That way, you'd be reachable via the same
address in both cases (plus a local one if you're on the local net; probably
faster for non-BackupPC traffic). Routing might be a little tricky. You'd
probably need to NAT to the VPN gateway address for connections from the LAN
to your notebook (via the VPN address) - something along the lines of

   iptables -t nat -A POSTROUTING -o tun0 -d 1.2.3.4 -j SNAT --to-source 1.2.3.1

(replace tun0 with the VPN device name, 1.2.3.4 with the notebook VPN address
and 1.2.3.1 with the VPN gateway VPN address). You'll also need to prevent
routing to your local subnet via the VPN when you're on the local subnet
(which OpenVPN with "push route ..." would do, for instance).

Or you could DNAT connections to the VPN address to the local address when
the VPN isn't connected (that's a DNAT in PREROUTING *and* an SNAT in
POSTROUTING, because you need to catch the return packets).

Requires some networking skills and possibly some experimentation, but it
can definitely be done. The ClientNameAddress variant is easier to implement
without doubt, but the VPN variant is more generic, i.e. it doesn't require
 to be able to handle multiple addresses.

If you need help with routing or firewall rules, feel free to contact me
off-list (hopefully, my MTA will behave ...), and I'll try to respond soon.

Holger

true enough. If that works for you, do it like that.

Unfortunately, that is probably the normal case, the point being remote
connections via the internet. You won't *usually* have your BackupPC server
on your firewall (or router, if you don't have a firewall), though there
might be instances where you do.

Well, you could port-forward the VPN traffic from your router/firewall to the
BackupPC server. If you're only using the VPN for BackupPC, that doesn't
sound unreasonable. If, however, you're using it for general access to your
home network, well, you're basically back to "running the BackupPC server
on your firewall", even if it might not look like it ...

I looked for a PID file in /var/run/BackupPC, but nothing is there. I am
assuming this is some leftover PID or SOCK file that needs to be renamed or
removed. Running ps -ax does not show any process running under pid 1289 or
by the name BackupPC.

Any ideas?

BackupPC keeps track of its own PID/status independently of systemd (or
whatever else is launching/monitoring it) in a file called “status.pl,”
which can usually be found in /var/log/BackupPC, unless you or your package
manager have placed it elsewhere.

You'll find the relevant variable under “pid” within this file, which as I
recall, you can either blank out, or set to zero. (I note that status.pl
contains a number of other things, so you probably don't want to just
delete it.)

My own systemd uses helper scripts to coordinate the state of status.pl
with the pidfiles and systemd, something which I thought was ridiculous
overkill when I saw the considerably simpler systemd's on this list (and
that's probably still the case) but it's something to consider if this
happens frequently.

If the VPN is configured as point-to-point with the other end on the
backuppc server, routing would take care of itself via the subnet
masks.  The backuppc server could always use the tunnel address with
just a little bit of extra overhead when the laptop is on the LAN.
The routing is only complicated if the endpoint is on a router or some
other device.

Also without extraenous output? You seem to be using rsync over ssh, and
rsync is quite fussy about messages that it does not expect. As a rule of
thumb, to a *Linux* computer,

   % ssh clientcomputer true
   %

should immediately display the next prompt as indicated above, i.e. nothing
extra, not even blanks or newlines. For Windoze, your mileage may vary, but
it probably won't. The actual invokation used by BackupPC (or rather rsync_bpc)
might include extra options to ssh, e.g. -q -x -l someuser ... include those
when testing.

Holger

sorry, really busy, two quick remarks:
Can't be too difficult to backport "this feature" (context = array argument
to ClientNameAlias possible) to 3.3.0. Supposing I find the time before
someone else does, I'd look at it ...

You *can* use a VPN locally, too. That way, you'd be reachable via the same
address in both cases (plus a local one if you're on the local net; probably
faster for non-BackupPC traffic). Routing might be a little tricky. You'd
probably need to NAT to the VPN gateway address for connections from the LAN
to your notebook (via the VPN address) - something along the lines of

  iptables -t nat -A POSTROUTING -o tun0 -d 1.2.3.4 -j SNAT --to-source 1.2.3.1

(replace tun0 with the VPN device name, 1.2.3.4 with the notebook VPN address
and 1.2.3.1 with the VPN gateway VPN address). You'll also need to prevent
routing to your local subnet via the VPN when you're on the local subnet
(which OpenVPN with "push route ..." would do, for instance).

Or you could DNAT connections to the VPN address to the local address when
the VPN isn't connected (that's a DNAT in PREROUTING *and* an SNAT in
POSTROUTING, because you need to catch the return packets).

Requires some networking skills and possibly some experimentation, but it
can definitely be done. The ClientNameAddress variant is easier to implement
without doubt, but the VPN variant is more generic, i.e. it doesn't require
 to be able to handle multiple addresses.

If you need help with routing or firewall rules, feel free to contact me
off-list (hopefully, my MTA will behave ...), and I'll try to respond soon.

Regards,
Holger

Re: [BackupPC-users] Updated BackupPC 4 Debian Packages

Hi!

So I've build rsync-bpc and the Perl module without the included 
zlib, to make the Debian  Security Team happy. 
I've sent you a pull request for rsync,
if you want to make this the default compilation option and if
there are no side-effects.

Re: [BackupPC-users] error log for new host

[Kris Lou]

Is there a trailing slash on your TopDir?

p.s. I just do straight rsync over SSH to OSX.  But know that whatever
permissions you use to access the client (or start rsyncd if you go that
route) needs permissions on the client data as well.

Duno, Adam, I'm still in v.3 for production use and no time to explore
v.4 (is it now rock-stable ?); this might change when Debian Stretch
will become the new stable (around mid june ?), but I must see about
solid version migration before any change can take place.


This seems a perfect use case for that, adding the local IP and the
remote IP as the two aliases, hence only a single "host" in backuppc,
consistent ordered backups all in one place.

This is really a nice feature, especially in this case.


PS, this probably only applies to BPC4.x and I forget what version the
OP is using.

He did not state it, just that he use mageia5, which, from their site
is a fork of mandriva - might work the same as rh: one click and it

Re: [BackupPC-users] error log for new host

[Jeffrey West]

I don’t know if this will help you, but this is how I backup my Macs.



Created a template for backing up Macs. The file is called
/etc/BackupPC/pc/macs.corpnet.com.pl.template
Copy this file to /etc/BackupPC/pc/computername.corpnet.com.pl
Edit the file and change the following line to include the proper hostname
or IP

$Conf{ClientNameAlias} = 'macs.corpnet.com';

On the Mac, you need to go to System Preferences, Sharing, and enable
Remote Login.
SSH into the Mac using the riptide.admin account and brown password
Run the following commands

dscl . -create /Users/backuppc

dscl . -create /Users/backuppc UserShell /bin/bash

dscl . -create /Users/backuppc RealName "BackupPC"

dscl . -create /Users/backuppc UniqueID "510"

dscl . -create /Users/backuppc PrimaryGroupID 20

dscl . -create /Users/backuppc NFSHomeDirectory /Users/backuppc

dscl . -passwd /Users/backuppc brown

dscl . -append /Groups/admin GroupMembership backuppc

sudo scutil --set HostName mbp-zrawley.corpnet.com

sudo scutil --set LocalHostName mbp-zrawley.corpnet.com

sudo scutil --set ComputerName mbp-zrawley.corpnet.com

dscacheutil -flushcache

Make sure to change the computer name on the last 4 lines. Login to
backuppc.riptidesoftware.com as the user backuppc and run the following
command

cd .ssh

cat id_rsa.pub

Copy the lines that it spits out

ssh mbp-zrawley.corpnet.com   <-- Change to match the client computer
you are setting up

Use the brown password

sudo -s

Use the brown password

mkdir /Users/backuppc

mkdir /Users/backuppc/.ssh

vi /Users/backupppc/.ssh/authorized_keys

Paste the lines you copied from before and save the file.

chmod -R backuppc:staff /Users/backuppc

Exit the SSH session on the client and then run the following command

ssh mbp-zrawley.corpnet.com   <-- Change to match the client computer
you are setting up

Make sure that is does not ask for a password
You should now be able to backup a Mac by adding it to the hosts at
http://backuppc.riptidesoftware.com
