If metadata collection was disabled during backup, a live browse is initiated by mounting the snapshot on a proxy (pseudomount) and the backed up extents are recalled on demand.
By default, snapshots are mounted on the source client. You can select any other compatible client from the CommCell Console.
Live browse requires a staging folder to store the extents and metadata. The size of the staging folder must be at least 4 GB. The recommended size of the staging folder is 10% of the restore data, and it can be as large as the restore data. If the size of the staging folder is smaller than the restore data, then the extents are pruned based on the LRU (Least Recently Used) algorithm, for the new extent restores. This might result in decreased performance during the restore operation.
Live browse might fail for VxFS volumes. To prevent live browse failures, mount the VxFS volumes in read-only mode. See Mounting VxFS Volumes in Read-Only Mode.
On Linux, configure the staging folder on the "X" File System (XFS). By default, the staging folder is in the job results directory. You can configure a different path to the staging folder.
Note
Live browse and file-level restore from block-level backups is not supported for tape libraries and cloud library that is configured as archive storage.
Procedure
-
From the CommCell Console, expand Client Computers.
-
Right-click the Client, and then click Properties.
-
In the Client Computer Properties dialog box, click Advanced.
The Advanced Client Properties dialog box appears.
-
To change the path to the staging folder, on the General tab, in the Block Level Client Cache Directory box, type the path to the staging folder.
-
Click OK.
Note
Before relocating cache, verify that no block-level browse and restore jobs are running. After the client cache directory is changed, you must restart the services and manually clear the old cache on the client computer.
