Suggest that you consider setting up a dump-cycle of 1 week, with a tape
cycle of three weeks (5 tapes/15 tapes for weekdays only, 7/21 tapes for
seven days-per-week cycles). This will permit you to send out a complete
set of backup tapes once per week (for example, sending out the previous
weeks tapes on Monday) and getting back the set of tapes from two weeks
ago in exchange. You then start reusing the three week-old tapes for the
current week. You will need to have three sets of tapes, in case it takes
more than a day to exchange the tapes with your offsite repository.
Week In-Use Off-Site To-Be-Reused
1 Set3 Set2 Set1
2 Set1 Set3 Set2
3 Set2 Set1 Set3
4 Set3 Set2 Set1
....
Because of the one-week dumpcycle, you will always have a complete set of
dumps of each file system in the off-site tape set. It will grow
increasingly out-of-date during the week, but storing your local collection
of tapes in a fire-resistant vault should reduce your risks to an
acceptable level.
As always, "Your mileage may vary..."

Subject: offsite strategies
Hi!
I'm new to Amanda; I'm more used to "traditional" solutions like
Networker or NetBackup. That being said, the setup I'm currently
administrating has been put in place by my predecessor and I'm wondering
if people are using Amanda in an "offsite" strategy, where there is one
"cycle" of tapes offsite (usually a few weeks old) and another cycle
residing onsite (ie. the current ongoing cycle).
My point is that I would like to be able to store a full cycle offsite
in case of a disaster so I can full rebuild all my machines without the
worries of having only partials full backups.
Any hints?
Ciao,
