Re: Backing up remote BackupPC?
just out of interest: I have two backuppc instances (4.x) running on two different locations. But they back up the same list of hosts. I was just thinking: what happens if I am going to backup the /var/lib/backuppc directory from server2 to server1 and vice-versa? As both servers? back up the same hosts there should be the same files, right? What happens with the disk usage on the host backing up the other? Due to some sort of deduplication I expect not too much increase on disk consumption.
Am I right?
No. If you're using compression (why would you not be using compression?) then I'd guess that you'll be backing up everything twice - one copy being the compressed versions of your original files, and one being the compressed versions of the compressed versions of the originals. Also there are logs which will be different, plus the directories in which the backups are contained are named after the backup number, so there's no reason for them to be the same on both backup servers - and if that were your goal I think you'd have difficulty achieving it. Why would you want to do such a thing? I'd think that you would be backing up a lot of information which is more or less useless, plus causing a lot of unnecessary network traffic and server load. It's very easy to configure BackupPC to ignore those directories. -- 73, Ged. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
