Requirements for using cascaded drive pools

In order to cascade tape drives, the tape drives must be the same drive type, such as DLT 32K. To determine the drive type, look in the tape drive's property page.

See Viewing storage device properties.


If a tape drive that does not support hardware compression is added to a cascaded drive pool, the hardware compression option on all other tape drives in that pool is automatically disabled. You can enable the hardware compression option on the other tape drives again, but the pool will then have mixed compression, which could make restore operations difficult.

Backup-to-disk folders cannot be placed in cascaded drive pools.
