[lug] Backups...

Also keep in mind the amount of time it will take to do a full backup
of 24GB. A SCSI drive running at 5Mbytes/second should do the
full backup in under 2 hours. A device running at 1Mbyte/second
throughput costs you almost 7 hours for the full backup. One reason
folks usually do incrementals. :-)

You might checkout the Tandberg 10GB/20GB NS20. It's a SCSI2
Travan. A bare drive runs under $400. There appears to be quite a
price jump to a 12GB/24GB drive, the Tanberg SLR24 costs nearly
$800. Media runs about $40 per cartridge.

HP makes a SCSI2 Travan, the Surestore T20I, at about $400. They
make a similar drive with Atapi/IDE, but I'm not certain of the
throughput of this interface.HP's DAT24I runs 24GB, but costs about

As for software, Amanda is good. Also checkout Kdat, it's
supplied with RedHat 6.0. It uses dds2tar and supports
multiple archives on a tape, selective bakups of files/directories at
one time, verification/restore of selected files in an archive, backup
profiles, GNU incremental backups, etc.

Hope this helps...
