[lug] Backups...

[Bonnell, Doug]

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
$850.

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...
