Hmm, restoring is a pita regardless from where ;-) . I have enough temp
space to be able to do a full restore in case of trouble

I agree that they´re not *that* much cheaper (at least DDS-2 tapes <->
large EIDE-disks) but a factor of 5 is a factor of 5 (90m DDS-2 tape
(2GB) is about USD 2, eg USD 1/GB tape <-> USD 5/GB disk). Then
there´s reliability (not a single tape has failed me in 7 years, but
at least 10 disks have. and I have had *much* more tapes than disks).

I don´t worry about speed, the box has all night ;-) . Also if I would
like to have hot-swappable disk-backup _and_ at least 8 full backups,
I´d have to buy 8 disks. And USD 1k is out of the question for me. My
DDS-2 drive, refurbished, costs ~ USD 70...

I like *full* backups, no hassles, no problems with different versions
etc pp.
I simply do a full backup every week or so, cycling through (at the
moment) 8 tapes.
