How about this, 1. Primary copies.
Set up another storage pool so that your migration hierarchy is diskp->tapep1->tapep2 Every day backup to diskp then migrate to tapep1. Limit tapep1's number of volumes to an appropriate percentage of your library. Set a migdelay on this pool of at least one day, and longer if you can afford the space. Periodically (daily or weekly depending on data volumes and library capacity) alter tapep1's migration percentage to migrate down to say 75%, then alter it back to 100% After the tapep1->tapep2 migration finishes, run a move media on all full tapep2 tapes to get them out of the library. TSM works best if you can keep a whole day's backups on disk, but this stuff will still work if you go direct to tape. 2. Secondary copies. Assume that a tape copypool exists called tapec1 Whilst your daily backups are still on disk, run a backup stg diskp1 tapec1. This makes a tape copy of last night's backups Then run a backup stg tapep1 tapec1. This makes a second copy of anything that went direct to tape or which was migrated from disk to tape before the backup of diskp1 was run. Finally run a backup stg tapep2 tapec1. This should normally do nothing. If it doesn't investigate why. Run a database backup to tape Manage off-siting of secondary copies with home-grown scripts, the DRM component of TSM or the Autovault product.

I have successfully created a TSM PD/PS/MC/POOLS and backed up a 265GB filesystem to TAPE. The TAPE pool definition is: VDE: Nolimit VDD: Nolimit REV: Nolimit ROV: Nolimit Overflow Location: offsite My question(s): What is the best method to 1) check the tapes out, 2) ensure the data is keep FOREVER, 3) is recoverable, at anytime, 4) whatever I am missing!!!
