[BackupPC-users] Avoid permission denied errors
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi there: I have been customizing the BackupPC installation and I use the method recommended at http://backuppc.sourceforge.net/faq/ssh.html#how_can_client_access_as_root_be_avoided I think is cool to avoid using root for rsync (or whatever method you use to backup). The problem is that if I use another user (other than root to backup, for example backuppc user), I get a lot of permmision denied at the log, refering this to files at for example in /etc. Obviously backuppc hasn't enough permmision to copy those files, and I was trying to figure it out how to authorize him. I have try to include him at root group, but I get no luck :( Anyone have any suggest about it?

[BackupPC-users] Backup to distant FTP Server
Hello all, I need to use backuppc with a distant FTP server as destination. So, I used curftpfs to mount my FTP connection to a local folder and choosed it as the root of my destination. This is working fine till the ftp serverc decide to stop the connection. As this time, backuppc cannot start anymore because it cannot very the hardlink between pc an cpool which is normal because my ftp is no mounted anymore. I dont know if there's a way to solve that because I'd like that the mount is made just before the backup starts and unmounted just after as I'm a newbie in Linux and Backuppc, I'm requested your help. Per advance, thanks very much Arnaud -- Simplify data backup and recovery for your virtual environment with vRanger.

I'm surprised you didn't get a 'ping failed' error on the down machine that would have blocked the backup attempt. The 'unable to read 4 bytes' message is not very helpful but it means that rsync didn't start up or connect correctly for one reason or another. -- Les Mikesell lesmikes...@gmail.com -- Simplify data backup and recovery for your virtual environment with vRanger.

Make a pre-backup script which checks that the ftp mount is up and
running. To my understanding this would be defined using
$Conf{DumpPreUserCmd} = '/bin/bash /usr/local/your_script.sh'; or
perl or whatever.
If you know any perl ruby or python then I suggest you leverage those
skills. Otherwise do a quick google for 'bash filetest'.

That said, I believe $TopDir is the BackupPC daemon's working directory (hmm, no, that doesn't seem to be true, but it usually has a log files opened under $TopDir/log, though the location may be changed). In any case, BackupPC doesn't really handle $TopDir disappearing too well, so you're bound to get into trouble if it does (actually, I'd consider it a bug if anything emulating a *file system* through FTP would not transparently reconnect if the server disconnects - such a severe bug, in fact, that I'd consider the software experimental at best and avoid it for any serious work). In any case, you should verify your assumption that this is working fine. * Are your link counts accurate, i.e. does pooling work, or do you in fact have N+1 independant copies of each file that should be pooled? * I'd expect BackupPC to be *extremely slow* on an FTP-based pool. What might seem to work on an empty pool with a small test backup set will almost certainly degrade over time with a growing pool and hash collisions. BackupPC is optimized for fast pool access and potentially slow client access, not the other way around. Why are you using an FTP server as destination? How distant is it (i.e. how fast or slow is the link)? What amount of data are you planning to back up? What are you trying to protect against? Chances are BackupPC is not the right tool for the task you have in mind, or at least isn't being used in the correct way. Hope that helps.

Normally you'd have moderately frequent wakeups where the actual
scheduling of the runs is controlled by other settings (which are
checked at each wakeup). Is there some reason that is a problem?
there might be, depending on what you abuse your PingCmd etc. for ;-). And you
might want to allow the disk to spin down if it is unused most of the day.
This is also the most effective way to enforce a global blackout. If you
*never* want automatic backups to run during a particular part of the day,
there is no point in scheduling wakeups.
However, I find two or three wakeups more useful than just one. If that one
wakeup is missed (because IncrPeriod is a few minutes too long), you don't get
a backup that day (with only one wakeup). Also, BackupPC_nightly is run on the
first wakeup (i.e. first entry in $Conf{WakeupSchedule}, whatever time that
is), and I don't want that running in parallel with backups.
In any case, no there is no command that triggers the equivalent of a wakeup,
but the part you are probably interested in - running backups which are due -
can be triggered with
BackupPC_serverMesg backup all
If it's the nightly cleanup you're interested in, that would be
BackupPC_serverMesg BackupPC_nightly run
In any case, BackupPC_serverMesg needs to be run as the backuppc user.
Regards,
Holger
