A simple or a GFS media pool can fail over to another tape library in certain cases. Failover is available in media pools that use multiple libraries. One tape library is always set as primary, and is generally used for processing data. The media pool can switch to the next library in the following cases:
- The tape library is offline.
- The tape library has no free tapes.
- The tape library has no free drives.
The libraries are failed over to by the user-defined order. On the next backup session, Veeam will try to switch back to the primary library. If it is still not available, the media pool fails over to the next library as defined.
To configure the tape library failover rules, use the Manage Libraries option in the Media Pool wizard. See Step 3. Add Tapes to Media Pool of the New Media Pool wizard for details.
