No tape backup solution is ever 'cheap', but DLT has been around long enough, and superseded by enough new technologies (LTO, AIT, etc,...) that it's certainyl at the lessuse an 8-tape changer that usually holds enough for a week's worth of backups.

No tape backup solution is ever 'cheap', but DLT has been around long enough, and superseded by enough new technologies (LTO, AIT, etc,...) that it's certainyl at the less expensive end of the spectrum. 40GB (~80GB compressed) per tape. We use an 8-tape changer that usually holds enough for a week's worth of backups. Any old DLT drive should work with FreeBSD, although you'll need a SCSI adapter to attach it to. I'd second the idea of a separate staging disk for backups, especially if (like us) you're forced to use Windows software to actually put the backups on the tape. We have a 250GB drive that the nightly dumps from various UNIX RAIDs go to - the tape system can then just pick up a few files via Samba, at its leisure. We can fit 1-2 weeks of compressed dumps on the staging disk, so we rarely have to go to tape for restores, plus we no longer have to use the (lame, slow, broken) Veritas UNIX Agent to back up the UNIX systems. As for RAID, we use Vinum, but only because I inherited a bunch of machines with hot-swap SCSI bays and no hardware RAID. It works well, once you have it set up, and I've even managed to swap out failed drives without a reboot :-) I'll definitely investigate the 3ware cards when I need to build a new RAID server, though.
