Configuring a Subclient for Block-Level Backups Using SnapProtect
By default, block-level backups are performed using the native snap engines. You can also use hardware snap engines to perform block-level backups.
If an SnapProtect backup operation on the native snap engine is in a pending or suspended state, or is killed, a snap clean-up is not performed immediately. To remove the un-useful snaps, you must delete the snaps manually or run a data aging job.
- From the CommCell Browser, expand Client Computers | Client.
- Right-click the client and then click Properties.
- In the Client Computer Properties dialog box, click Advanced.
- In the Advanced Client Properties dialog box, select the Enable SnapProtect check box, and click OK..
- From the CommCell Browser, expand Client | File System | defaultBackupSet.
- Right-click defaultBackupSet, point to All Tasks, and then click New Subclient.
- On the Advanced Options tab, select the Optimized for File system with large number of small files(Block Level Backup) check box.
- To perform a faster file-level browse and restore, select the Create File level Index during backup check box.
Depending on the data scan type selected, backups might take longer when you enable this option. Selecting Optimized Scan reduces the overall snap backup duration because the scan phase runs faster.
- On the SnapProtect Operations tab, select the SnapProtect check box.
- Select a Snap Engine from the Available Snap Engines list.
- From the Use Proxy list, select the MediaAgent where SnapProtect and backup copy operations will be performed.
When performing SnapProtect backups using the proxy, verify that the proxy server is either installed with the same operating system version, or later, as the client computer.
- If you want to perform backup copy operations in a different MediaAgent, click Use Separate Proxy for Snap to Tape, and then select the MediaAgent from the Proxy list.
- Select additional options as appropriate for subclient creation and click OK.
