It's true, but amanda allows for a holding disk that the backups get
sent to, so the dumps themselves don't take so long. So, the other
machines that are being backed up, and do the real work in house, don't
take any longer then when I had a tape drive on the backup host. From
the holding disk on the backup machine they get dumped to the USB
external disk drive and it's not real important how long that takes,
it's true you would want it done before the next backup started though.
I don't use the backup machine for too much more then just doing the
backups. It's an old relatively slow desktop machine that was put out of
use when we got some upgraded machines. The stats from amanda show that
things have settled down to average backing up something like 10 GB a
day and that seems to take anywhere from 3 to 5 hours which isn't a
problem.
Thanks
