To go along with the ADP story I have moved this older post up for easy reference.
With the release of TSM 5.4 Tivoli has added the ability to create an active data storage pool to allow for faster restore times. We have been looking into using them at work when I stumbled upon this interesting factoid in the description of the active data pools limitations:
- The server will not attempt to retrieve client files from an active-data pool during a point-in-time restore. Point-in-time restores require both active and inactive file versions. Active-data pools contain only active file versions. For optimal efficiency during point-in-time restores and to avoid switching between active-data pools and primary or copy storage pools, the server retrieves both active and inactive versions from the same storage pool and volumes.
