From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Sparrman In my experience, I see almost no case for fault tolerance in TSM-based disk systems that normally perform a daily migration to a tape-based primary storage pool. If a system crashing prior to migration worries you, perform your migration as early in the day as you can after clients finish running their backups to a cached disk pool. What would be wrong with running migration during the backup process? I have client backups running around the clock and I also run migration around the clock. I have a lot fewer disk drive than storage pools, so I have a process that runs migration on one disk pool at a time. I've had no issues with performance, but I was wondering if I've overlooked any other got-you's Ray Baughman
