Indeed. I've found that the default time of midnight is a very poor one...
that's when you typically want your backups to be going off. I usually
reschedule mine to go off at 8am or so; but noon might actually be better.

$Conf{WakeupSchedule} = [8..24,1..7];

you can find the directory in the backup tree (under the per-pc
directory),
and just do an rm -rf on it. Afterwards, you can invoke BackupPC_nightly
with something like /path/to/BackupPC_nightly 0-255 (if I remember
correctly); or wait overnight for it to run on its own.

I had used the above command previously. Just an additional note, logged 
in as the backuppc user on my backup server, if I execute 
/opt/local/BackupPC/bin/BackupPC_dump -i feuerstein, a complete 
incremental does work properly, just if the backuppc daemon executes the 
BackupPC_dump, it fails

[BackupPC-users] Delete directory from backup

[Keith Edmunds]

BackupPC version 2.1.1 using rsync. 

Owing to a typo in $Conf{BackupFilesExclude}, a large directory has been
backed up that should have been excluded. What steps should be taken to
remove that directory from the BackupPC server and recover the pool space
(the latter presumably not until BackupPC_nightly runs)?

Thanks,

[BackupPC-users] Time to upgrade from 2.1.2?

[Miles Thompson]

We used apt-get to fetch and install BackupPC on our Edgy Eft server.
The version is apparently 2.1.2 dated  5 Sept, 2005 according to the
comments in the main BackupPC file.


It's only been running a couple of weeks; would an upgrade be painful?
Are there clear advantages?

Have you tried to ssh from the new server to the host as user
backuppc? 

/usr/bin/ssh -q -x -l root feuerstein 

I guess the ssh host key of your new server has changed or something
else with ssh.

[BackupPC-users] Problems after upgrade to BackupPC 3.0.0

[Hamish Guthrie]

Hi,

I have migrated my BackupPC pool to a new server and after having done 
that I upgraded my BackupPC from 2.1.1 to 3.0.0. I am able to back up 
one of my host only, and that is a Windows machine using rsync. All of 
my other hosts are Linux machines and I get the following error:

incr backup started back to 2007-05-10 20:00:01 (backup #7) for 
directory /clmirror/feuerstein
Running: /usr/bin/ssh -q -x -l root feuerstein /usr/bin/rsync --server 
--sender --numeric-ids --perms --owner --group -D --links --times 
--block-size=2048 --recursive . /clmirror/feuerstein/
Xfer PIDs are now 6693
Read EOF: Connection reset by peer
Tried again: got 0 bytes
Done: 0 files, 0 bytes
Got fatal error during xfer (Unable to read 4 bytes)
Backup aborted (Unable to read 4 bytes)

Any ideas would be most welcome

I'm curious why BackupPC's archive method wouldn't work for you.  I use it
to burn DVDs of my backup sets on a periodic basis.  Couldn't you do that 
and store the DVDs offsite?  

They aren't in "BackupPC" format, they are written as compressed tar
files, which can be read on just about any out-of-the-box Unix or Windows
system without any special tools or anything specific to BackupPC.

Re: [BackupPC-users] Advice on BackupPC

Hi Les

I've looked into this in the past, and the two main problems are a) the
proliferation of .svn directories and b) the inability to restore file
metadata (owner, permissions, etc). There are other svn-like programs that
overcome these issues.

It might also be interesting to try the subversion version control 
system for something like this since it has a binary difference 
mechanism built in.  You'd have to do some extra planning to use it for 
backups though, because it wants to keep an extra copy of the previous 
repository version locally (so it can compute the diffs to commit) and 
there is no easy way to ever remove anything from the repository.  You'd 
probably want to create new repositories on some schedule so you could 
delete the old ones completely.

Subject: [BackupPC-users] "Restore" a backup to DVD ?


Hello,

I am using backuppc to backup something like 30 servers. All that servers
are in one place. The backup host is among them so in case of emergency
(fire, e.g.) I need to have backups in a different place.
So I'd like to burn DVDs which I could send to various places to keep my
data safe. Is there a way to "restore" a backup and save it to a DVD (or on
a given directory which I could burn on a DVD...). In fact, I'd like to get
"raw" backups consisting of all my files without the backuppc format. Do you
see what I mean ? Is there a simple way to do it ? Did I miss something
obvious ?
Alternatively, if I want to save on DVD a full backup of a given host,
directly from the files in ~, what do I need to save ?
~/pc/my_host/0 (or 1, ..) ? Is it possible to reinsert that
backup on a fresh backuppc install (from scratch) and use the web interface
as if the backup had been generated by that instance of backuppc ?

Thanks in advance,

Anthony

ACL and xattr support is coming with rsync 3.0 which is still CVS.
There are also patches for 2.6.x to support ACL's. I used star to copy
a large amount of data with ACL's between 2 server. This was working
quite well. But star or a patched rsync version are not supported by
backuppc.

Backup your ACL's and xattr's to a text file (getfacl, getfattr).
That's not an very practicable  solution, because you might miss some
ACL's if you run a cronjob for this only a few times a day.

I would also be interested in a backuppc solution for this. At the
moment this is what I miss most (by far) in backuppc.
