I simplified your questions a little. In the context of backup-to-disk
vs. backup-to-tape, consider this too.
Modern OS's can do snapshots of their filesystems (at least one of the
later releases of Solaris 8, and the volume man

Frank,
Tom,
I was thinking the same thing, though where possible I have a
couple of extra anyway (2 x runs/cycle + N) for small values
of N.
Tom, whatever I said, ignore it, you are in reasonable good shape,

Tom,
If all goes well you will have at least one level 0 of each
partition during the dumpcycle.
With only a single dumpcycle of tapes in the tape pool you may
find that you lose your only level 0 if there are any problems,
ie: bad physical tape, need to do flushes, dirty drive...
How many more

Ok for due, I guess it means I will have to backup that host in two
days, and that other in three days.
But for overdue ? Does this mean I **will** have to backup that host

As we're speaking about terminology, there are things I don't understand
as english is not my native language :
Amongst them, I don't understand the term "due". Could anyone explain me

This is what I understoond by the terms "dumpcycle", "runspercycle" &
"tapecycle". Please correct me if I have misunderstood these terms.
dumpcycle 2 weeks:
Full backups of all shares will be done once in every 2
weeks (or 10 days - excluding weekends (sat/sun))
runspercycle 10:
