Creating Safeguarded backup locations

Edit online

A Safeguarded backup location is a child pool in each parent pool where the source volumes are located. The Safeguarded backup location stores Safeguarded backup copies after the Safeguarded policy is assigned to the volume group.

With the Safeguarded Copy function, child pools provide a Safeguarded backup location for a group of volumes that are associated with the parent pool. The Safeguarded backup location can contain many snapshots of volume data, each created at a specific interval and with a defined retention period to satisfy your recovery point objective. After the Safeguarded backup location is created, you need to create a volume group and assign a Safeguarded backup policy to the volume group.

Using the management GUI

To create a Safeguarded backup location, complete these steps:
  1. In the management GUI, select Pools > Pools.
  2. Right-click a parent pool and select Create Child Pool.
  3. On the Create Child Pool page, enter a name of the child pool.
  4. If the parent pool is a standard pool, enter the amount of capacity that is dedicated to the child pool. If the parent pool is a data reduction pool, the child pool shares capacity with the parent pool.
  5. Select Safeguard to indicate that the child pool is used as the Safeguarded backup location for immutable backup copies of source volumes.
    Note: Before a Safeguarded policy can be applied, create one Safeguarded backup location for each parent pool. After you create the corresponding Safeguarded backup locations for each parent pool, create a volume group for the all the affected source volumes.
  6. Select Encrypted to encrypt the child pool. If the parent pool is encrypted, the child pool adopts encryption from the parent.
  7. Click Create. Child pools that are used as Safeguarded backup locations are marked with a shield icon on the Pools page.

After you create the Safeguarded backup locations, create volume groups.

Using the command-line interface (CLI)

To creates a new child pool to be used as the Safeguarded backup location for parent pool, enter the following command.
mkmdiskgrp -size mdiskgrp_size -parentmdiskgrp mdiskgrp_id | mdiskgrp_name -name pool_name -safeguarded
where mdiskgrp_size specifies the child pool capacity. The mdiskgrp_id | mdiskgrp_name specifies the parent pool from which the volume extents of the child pool are allocated when you create a child pool. The -safeguarded parameter specifies whether the child pool is used as a Safeguarded backup location.
