[OT] Removal disks for backups
I'm currently backing up my workstation data to a spare internal
disk. This is nice because a few cron tar scripts do the job
every night without my intervention. A spare IDE disk is very
cheap, and I don't keep the partitions mounted so nothing happens
to them. The downside is that I have no offsite backup (should a
fire arise or something like that).
I'm therefore thinking of buying a removal disk for offsite
backups. My current backup needs are 1.9GB after full
compression, although this will likely grow (doesn't it always).
I have a PD drive but 650 MB is too limiting (splitting the
directories so the compressed tar file fits; not forgetting to
switch disk every night).
I am considering getting a Castlewood Systems (http://www.castlewood.com/)
ORB 2.2 GB external SCSI drive. See a review at
It's pretty cheap (US$230 and US$35 for extra disks) and seems
very fast (11ms read/ write 12ms; 12.2 MB/sec max sustained
transfer rate? Heck I don't get that from my Barracuda!)
Ideally, a 4GB cartridge would be better, but I suppose when my
needs outgrow 2.2 GB compressed I can swap disks on some night
before I leave work.
Any comments about this device? Anything better on the market?
