Re: [BackupPC-users] How scalable is backuppc?

What would be nice is to seperate the Web interface from the backuppc servers and allow one interface to manage a number of backuppc servers.

I am not so concerned with how well backuppc scales as I prefer to partition out my backup scheme rather than throw ever more powerfull and expensive hardware at scaling.

About 30 are active, 12 are sporadic (laptops, etc). Total that gets
written out to off site backup is about 300GB of data a day, compressed.

No. Default options for Debian etch. This filesystem has been
xfs_growfs'd a few times after being dd'd to a new volume, since it's
impossible to back it up with xfsdump|xfsrestore. I mount with noatime,
and logbufs=8

6.4TB, and 2.8TB is in use, with 2TB or so of that being backuppc's.
