(apologies for the reply to an old thread)

Erm, we do exactly that. Nightly full backups onto two LTO tapes
(different data on each tape, not a duplicate copy). One person takes
one tape, another person takes the other tape.

I personally try to ensure that there is always at least one recent tape
at home at all times.

Tape rotation is such that we can go back around 6 months, although the
further back you go, the sparser the options are for backip dates to
restore from (daily backups for the past week, then weekly backups up to
4 weeks ago, then monthly backups from thereon).

I'm undecided as to whether or not to keep one of the monthly tapes
read-only every 6 months so that we could go back further. We seem to
change the format of media every 3 years or so, which has its own
problems (if you have the tape, but no hardware to read it, restoring
from the backup could be time consuming and costly)
