Hello,

What's a good program to making complete snapshots off a dedicated server?

Thnx in advanced

We use rdiff-backup here

That depends on what your definition of snapshot is. If you want *true* snapshots then rdiff-backup is not gonna cut it. It will backup your files just fine (like BackupPC, which is what I use), but it will backup each file one after another and doesn't necessarily give you a true point-in-time snapshot of a filesystem.

* If you use LVM you could use its snapshot support.
* If you use a filesystem which supports snapshots (e.g. btrfs, Reiser4?) you could use that.

If you don't need true point-in-time snapshots, but are just looking for backups, then tools like rsync/rdiff-backup/BackupPC will probably do the job just fine and they don't require LVM or specific filesystems.

I assume he means a snapshot backup. Is that what you meant?

If so, you can roll back with rdiff-backup and BackupPC and you can create point in time backups with rsync backup if you use a branching tree. The branching tree method is easy to use but requires a little skill to setup, the roll back method with rdiff-backup is a little more work to use, but its automatic and very easy to setup up. BackupPC is very easy to use, but requires some work to setup.

If you want backups, NEVER rely on file systems snapshots EVER. A snapshot is not a backup. If you lose the drive(s) or file system you're hosed. A snapshot is a local point in time copy of the filesystem, not a backup.

Sure. Although a cool trick is to create a file system snapshot and back that up.

Yep, we do both. I just dont anyone to make the fatal error of assuming a snapshot is a backup, its a copy, a *local* copy. :-)

Heres a quick forum post I made about how to set this up:

I also recommend backuppc.
