Re: [BackupPC-users] Slow link options
2009-12-18 15:48:05
I was able to get a full backup on 3 of the 4 servers. Two of them I was able to take the backuppc machine to the location and the third it was small enough to be able to complete over the T1. However we have one remaining remote location that has approximately 309GB of data that needs backing up. This initial full will take anywhere in the range of 10-20 DAYS according to my numbers.
However, we do have an rsync of that server on another in-house server. It is a complete rsync minus a few directories like /proc /var etc. So we don't have to take the backuppc machine 3 hours away, does anyone know if it would be possible to somehow setup backuppc to use the complete existing in-house rsync as the base for the initial full backup?
The setup on the rsync backup is that the entire backup is stored in /server/servername. Since backuppc stores the files in relation to the root directory how would I move the files from /var/lib/backuppc/pc/rsync-server/0/f%2fserver%2fremoteserver to /var/lib/backuppc/pc/remoteserver/0/f%2f? Should it be as simple as moving the folders? Or is this even possible?

backup data. Once you get the initial full, rsync backups only transfer
changes. Have a look at the documentation
(http://backuppc.sourceforge.net/faq/BackupPC.html#backup_basics) for
more details.
