Hey roy,
this does not sound like a problem with TSM.
Possible scenario:
- create extra storage pools for Archives
(DiskA/primary, TapeA/secondary/NotCollocated and TapeB/backup)
- point your archives into DiskA
- run regular
backup stg DiskA TapeB
backup stg TapeA TapeB
(the second one will usually do nothing,
this is just for case your archive run is larger as DiskA)
- each time a tape in TapeB becomes full, send it offsite and mark it as
offsite (upd vol ..).
- regulary check status of tapes in TapeA, (q vol stg=tapeA)
checkout full ones out of library,
and keep them offline but onsite.
This way you have both offsite backups for case of fire etc.
and onsite backups for case of casual restores.
Another point: if you are going to keep tapes for 7-10 years,
you should consider refreshing them
(e.g. move data a_TapeFromTapeA DiskA)
How often you shall do it depends on technology you use.
best regards

Subject: How do I know what tapes my data is on? - Part II
Sorry Guys,
Maybe I didn't explain myself very well. Here is the situation:-
We have a customer who now requires that EVERY month, an archive is
taken to a management class that may be 7 or 10 years.
Obviously over a period of time, this data will be migrated from disk
to tape, and then the ONSITE copies will just sit in the library taking
up valuable slots.
I don't want this to happen!. Over a prolonged period, we will run out
of slots!. So, the solution that I came up with, is to save directly to
tape, and then send those tapes offsite, thus "freeing" up the slots.
Now obviously, this is NOT an ideal solution, I realise that!. But what
other options do I have?.
Kind Regards,
