Dell NetWorker 19.9 Administration Guide

Matching the pool criteria with Legacy Backup Rules enabled

After a migration and configuring media pools, data generated by an action might match the criteria for more than one media pool configuration. For example, if you configure one media pool to accept data from a client that is called mnd.corp.com, and you configure another media pool to accept data from all full backups, NetWorker uses other criteria to determine which pool of volumes receives the data from a full backup of the mnd.corp.com client.

The NetWorker Server uses the following media pool selection criteria:

1. Groups attribute (highest precedence)
2. Clients attribute
3. Save sets attribute
4. Levels attribute (lowest precedence)

When data matches the attributes for two media pools, for example, Client and Level, the data is written to the media pool specified in the Client attribute. For example, in the case where the data from the client matched the criteria for two different media pools, the data is routed to the media pool that accepts data from the mnd.corp.com client.

The following table details the hierarchy that the NetWorker Server uses to determine media pool selection when a conflict arises. For example, the media pool criteria for Groups takes precedence over the media pool criteria for Clients, Save sets, and Levels. If data does not meet the criteria for any customized pool, NetWorker writes the data to the Default media pool.
