usb is way too slow for that, not mention that the design of usb is one ofBill said:Don't forget that tape backup is expensive, that tapes are not used for
anything else while DVD is used on many systems for data transfer, the
individual media are cheap, and the cost of a 2nd drive is minimal.
Having a 2nd tape drive (or a reasonable size) is very expensive, not
having a 2nd tape drive means you don't have a backup if the 1st one
fails. I've seend that twice in 30 years, and both times the manager's
career took a major hit for not having a backup drive.
There's no help in sight, DL DVDs are too expensive (thanks to DRM for
that), and 25-30GB Blueray or HD-DVD blanks are also unlikely to be
affordable. Any tape format large enough to be useful is expensive, both
drive and media. You can put a TB of disk in for <$1k, but you can't do
a decent backup system for that.
What the world needs is a cheap four bay external usb drive case, put in
four big drives as RAID-5, take a backup and put it in the safe. Don't
know of any.
Anyway, DVD is used instead of tape because you have it anyway, tape has
no other use but backup in most cases.
the worst kluges in history. external SATA would be a much faster and
better option, probably cheaper too.
