A media pool refers to a Veeam configuration entity used to set up tape archiving via Veeam backup console. It represents a logical group of tapes (either predefined or custom) for which you can configure the settings you need, in particular:
•Include or exclude tapes to/from the group
•Assign a physical sequence of tapes (media set) to this group
•Force or do not force Veeam Backup & Replication to override data on tapes included in the group (that is, apply desired retention settings for tape media)
For detailed information, please refer to the Working with Media Pools section of Veeam Backup & Replication User Guide.
Veeam Backup & Replication supports the following retention/override policies for the media pools:
•Do not protect data (cyclically overwrite tapes as required) - this option allows for data override and is used when your retention policy prescribes to keep at least 1 latest restore point on tape.
•Protect data for [x] - this option is used if your retention policy prescribes to ensure that data is stored in tape archive for the specified period of time.
•Never override - this option can be used, for example, if you plan to permanently keep tape archive and clear tape records ad hoc (in a non-scheduled way).
Usage examples for media pool options are provided later in this guide.
