I am looking for a simple backup program that I can use to backup a CentOS box to a local tape drive. Hopefully someone here can give me a recommendation.
This is what I need: - Simple launching of manual backups (preferably from the command line) - Ability to span tapes for a large backup - Proper treatment of hardlinked files - Notification via email or similar when it is ready for the next tape.
I tried mondo-rescue, but decided against it after it spent 4 hours just trying to index the files (it never actually started the backup).
I am considering Amanda, but the setup is a bit complex and, based on the docs, the tape spanning capability isn't the best.
Anyone have any suggestions? I would think that there would be a simple program out there to backup and restore from tape without all of the extra scheduling and indexing features.
I used that for years, but the network grew and needed a "bigger" solution so I switched to backuppc which is working great.
I'm using backuppc. I just need something to dump the backuppc machine to tape for an offsite or last-resort backup. The problem is that backuppc is currently using 161GB (compressed) and the tapes only hold 40GB each, so I need something with some sort of intelligent tape-spanning capability.
I haven't seen flexbackup. I'm currently evaluating afbackup.

You are going to have more trouble than that. Backuppc will have millions of hardlinks in that 161GB and nearly all file oriented backup programs will take an impractical amount of time to deal with them. And restoring will be even worse - basically everything ends up building a table of inode numbers and scanning it for a match on every hardlink.

You really want a matching external hard drive so you can dd an image copy to it. There has been quite a bit of discussion on this topic on the backuppc mail list and I'm not sure anyone has come up with an ideal solution. Or, you can use the 'archive host' feature of backuppc to generate tar images of backup runs optionally compressed and split to fit your media, but these are copies of individual hosts and you loose the pooling feature.
