PowerProtect Data Manager 19.12 Administration and User Guide

System pool limitations

Before you use system pools, review the following information:

• If the primary backup or retention targets a system pool, PowerProtect Data Manager removes this system pool and the individual pool members from the list of available replication targets. This limitation prevents a protection policy from inadvertently replicating to the same protection storage system that holds the primary copies.
• Storage Direct policies do not support system pools. The storage target list shows all protection storage systems, regardless of membership, but does not show system pools.
• Cloud Tiering does not support system pools. If the primary backup or retention targets a system pool, you cannot add a Cloud Tiering objective to the protection policy. If the replication objective targets a system pool, you cannot add a Cloud Tiering objective to the replication objective.
• Server disaster recovery (DR) does not support system pools for protection policies. Protection policies that target system pools do not synchronize to the remote server.
• Server DR does not support system pools as a recovery target. The list of target protection storage systems does not include system pools.

• When automatically creating a mobile storage unit on a system pool for a protection policy:

  • If the policy encryption setting is enabled, PowerProtect Data Manager requests placement on a pool member where DD Boost file replication encryption is enabled.
  • If the policy encryption setting is disabled, PowerProtect Data Manager makes no specific placement request. The mobile storage unit may reside on a pool member where DD Boost file replication encryption could be either enabled or disabled.
  • The retention lock setting for the system pool and pool members must match the retention lock setting for the protection policy. If retention lock is disabled for the system pool or pool members but enabled for the protection policy, or conversely, mobile storage unit creation fails.
