Changing storage targets

A storage target consists of a protection storage system and associated storage unit. You can change the selected storage target elements for each protection policy.

When you edit the primary backup and replication objectives for protection policies:

  • The Storage Name drop-down list shows the current protection storage system. The drop-down list also contains other protection storage systems that are available. Select Add to configure more protection storage.
  • The Storage Unit drop-down list shows the storage unit that PowerProtect Data Manager targets on the selected protection storage system. From this drop-down list, you can select other storage units under the control of PowerProtect Data Manager. Select New to create a storage unit.

When you change the storage target, appropriately configure any dependencies. For example, configure a cloud provider for the updated storage target in the dependent protection policy objective.

NOTE Network interfaces that exist on a DD 7.4.x or earlier system and that are configured to use an uncompressed IPv6 format cannot be discovered. An example of an uncompressed IPv6 format is 2620:0000:0170:0597:0000:0000:0001:001a. An example of a compressed IPv6 format is 2620:0:170:597::1:1a. To use these network interfaces, reconfigure them to use either an IPv4 address or a compressed IPv6 address, and then initiate a discovery.

Impacts

Changing the primary objective storage target for some asset types may cause skipped backups until the next scheduled full backup:

  • VMware virtual machine application-aware
  • SAP HANA
  • Oracle RMAN

Perform a manual full backup for these policies. Manual backups of protected assets provides instructions.

The following asset types do not require additional action:

  • VMware virtual machine crash-consistent
  • Kubernetes
  • Network Attached Storage (NAS)
  • Storage Group
  • Microsoft Exchange Server
  • Microsoft SQL Server
  • File systems

For these asset types, the next backup automatically becomes a full backup.

Replication objectives do not require additional action.

Protection storage

Managing Storage provides more information about working with protection storage, including configuring additional protection storage systems and changing quota settings.

When reviewing the list of selected and available protection storage systems, consider the following:

  • It is not recommended that policy objectives share protection storage systems because this configuration does not increase data availability. However, some environments may require replicas with different retention periods, where multiple objectives share a protection storage system.
  • Only protection storage that has been licensed and configured for use by the current protection policy appears in the drop-down list.
  • Changing protection storage systems for Storage Group protection policies is not supported.

Storage units

Storage units provides more information about working with storage units, including applicable limitations and maintenance considerations.

If you select New, PowerProtect Data Manager creates a storage unit for this protection policy. The new storage unit name is based on the protection policy name plus an identifier. Storage units provides more instructions for changing the quota configuration.

You can also select an existing storage unit under the control of PowerProtect Data Manager. The drop-down list displays the available storage units on the selected protection storage system. If the storage unit name is truncated due to space limitations, hover over the list entry to see the full storage unit name and quota information.

Changing storage units for Storage Group protection policies is not supported.
