PowerProtect Data Manager 19.10 Administration and User Guide

Changing storage targets and storage units

You can change the storage target or storage unit that PowerProtect Data Manager targets for each protection policy.

When editing protection policies in the PowerProtect Data Manager UI, for the Primary Backup and Replicate schedules on the Objectives page:

  • The Storage Name drop-down list shows the current storage target and those storage targets that are available for the protection policy.
  • The New and Existing options for Storage Unit show the current storage unit that PowerProtect Data Manager targets on the selected protection storage system.

Storage targets

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

  • The selected storage target for Storage Name in the Primary Backup row does not appear in the drop-down list for Storage Name in the Replicate row.
  • The selected storage target for Storage Name in the Replicate row does not appear in the drop-down list for Storage Name in the Primary Backup row.
  • Only those storage targets that have been licensed and configured for use by the current protection policy appear in a drop-down list.
  • If a storage target exists but does not appear in a drop-down list, click Add at the bottom of the list. Configure the storage target for use with the protection policy.
  • When a storage target is changed, a new storage unit name is automatically created, and the configuration is passed to any backup agents.
  • Changing storage targets in Storage Group protection policies is not supported.
NOTE

Changing the storage target for Primary Backup may prevent any scheduled backups from being performed until after the next full backup. To ensure that all scheduled backups are performed on schedule, click Back Up Now from the Protection > Protection Policies pane.

This guidance does not apply to VMware crash-consistent or file system backups for Primary Backup. For those asset types, you can change the storage target and all scheduled backups happen without further action. This guidance also does not apply to replication.

When you change a storage target, appropriately configure any dependencies. For example, configuring a cloud provider to use the new storage target.

Storage units

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

When you select New, PowerProtect Data Manager maintains a dedicated storage unit for this protection policy. Click Set Storage Quotas.

Set the capacity and stream quotas that restrict the storage unit resource consumption.

There are two kinds of quota limits—hard limits and soft limits. You can set either a soft or hard limit or both a soft and hard limit. Both values must be integers, and the soft value must be less than the hard value.

NOTE When you set a soft limit and the limit is reached, an alert is generated but data can still be written. When you set a hard limit and the limit is reached, data cannot be written. All data protection operations fail until data is deleted from the storage unit. The PowerProtect DD Virtual Edition Installation and Administration Guide for the appropriate platform provides more information about quota configuration.
  • Capacity Quota—Controls the total size of precompression data that is written to the protection storage.
  • Stream Quota—The number of concurrent streams allowed during data protection operations. Setting a Stream Quota limit can help ensure that performance is not impacted negatively when a data protection operation consumes too many resources.

When you select Existing, the protection policy targets a storage unit under the control of PowerProtect Data Manager. Click Select.

The Select Storage Unit dialog box opens and displays a list of the storage units under the control of PowerProtect Data Manager.

Select a storage unit from the list, and then click Select.
