Re: [BackupPC-users] Backup backuppc pool with rsync offsite
2011-02-22 22:20:00
13,849 items, totalling 3.8 GB
It would appear that I have a feasible number of files. I'm not sure how many more files I will have by the end of April, though.
I've read about that "rsync -H" would be a practical command to use on the backuppc folder.
What I'm also curious about is if I should be rsyncing any other files, thus allowing me to restore from the offsite backup in the case I lose everything and rebuild a backuppc configuration: I would attempt to rsync back to my computer with the new backuppc configuration and attempt to restore/recover said files.

rsync'ing the BackupPC data pool is generally recommended against. The
number of hardlinks causes an explosive growth in memory consumption by
rsync and while you may be able to get away with it if you have 20GB of
data (depending on how much memory you have); you will likely run out of
memory when your amount of data gets larger.
future versions of backuppc may deal with this problem better.
There are ways of replicating the backuppc data pool remotely; but I have
not tried them myself.
