Media pools are logical containers created in Veeam Backup Free Edition to organize and administrate tapes. Veeam Backup Free Edition works only with tapes that are placed to one of media pools. To introduce tapes to Veeam Backup Free Edition, you need to run importing procedure against all new tapes you load to your tape devices. Importing registers tapes in the Veeam Backup database after which Veeam Backup Free Edition places tapes to one of the media pools.
Veeam Backup Free Edition has a number of service media pools that are used for automatic tape administration. For example, all new tapes are placed to the Free media pool. To write data to tapes, you need to manually create at least one simple media pool.
All Veeam media pools are global. They span tapes that belong to multiple libraries. In a global media pool, you can move tapes between the libraries without need to catalog them. For example, if you need to restore data from tapes, you can insert the tapes into any tape library in the pool.
Mind the hardware encryption. If the tapes are encrypted by native hardware means of a tape library, you cannot read them at tape device with another encryption standard or with hardware encryption turned off.
