Configuring a Subclient for PostgreSQL Database Block-Level Backups Using SnapProtect

Use hardware snap engines to perform block-level backups using SnapProtect.

You can configure a default subclient to protect your PostgreSQL instance. You cannot create a user-defined subclient to perform a block-level backup.


You must have a MediaAgent installed on the PostgreSQL destination client to perform block-level backups.

Before You Begin

Before you begin, check whether you completed the following tasks:

  1. Create a storage policy
  2. Create a snapshot copy for a storage policy for block-level backup


  1. From the CommCell Browser, expand Client Computers > Client.
  2. Right-click the client and then click Properties.
  3. In the Client Computer Properties dialog box, click Advanced.
  4. In the Advanced Client Properties dialog box, select Enable SnapProtect, and click OK.
  5. To configure the default subclient of PostgreSQL, from the CommCell Browser, expand Client Computers > Client > PostgreSQL > Instance > FSBasedBackupSet.
  6. Right-click the default subclient and then click Properties.
  7. On the General tab, in the Subclient box, type a name for the subclient.
  8. On the Storage Device tab, from the Storage Policy list, select an appropriate storage policy.
  9. To set up your block-level backup, on the Advanced Backup Options tab, select Use Volume Copy.
  10. On the SnapProtect Operations tab, select SnapProtect.
  11. From the Available Snap Engines list, select a snap engine.
  12. Optional: From the Use Proxy list, select the MediaAgent where the backup copy operations are performed after the SnapProtect operation is complete on the client.

    Note: When performing SnapProtect backups by using the proxy, verify that the proxy server is installed with the same operating system version, or later, as the client computer.

  13. If you want to use the source computer when the proxy is unavailable, select Use source if proxy is unreachable.
  14. Select additional options as appropriate and then click OK.
