Move Mount Path

You can move a mount path from one location to another location on the same MediaAgent or across different MediaAgents. The destination path can be a local path or a network path. When you move a mount path, the deduplicated and non-deduplicated data that resides on the mount path is moved to the new location.

Moving a mount path is suggested in the following scenarios:

  • You want to move to another location that has more storage capacity.
  • You want to move to a faster disk media.

When you move a mount path, the system takes the following steps:

  • Validates the source and the destination mount path folders
  • Copies the contents from the source mount path folder to the destination mount path folder

Note: Although you can use the Windows file copy operation to change the location of a mount path, Move Mount Path is more reliable. Move Mount Path performs checksum verification of the data to ensure that the data is available for further backup and restore operations. Because Move Mount Path performs checksum verification, it might be slower than the Windows file copy operation.

Mount Path Configuration Support

Supported Mount Paths

  • A disk library with multiple disk devices. For example, a disk library Lib1 with disk devices Device_1 and Device_2.
  • Multiple disk devices pointing to the same path on the same disk library or on multiple libraries. For example:
    • Disk devices Device_1 and Device_2 pointing to path D:\MP1 on disk library Lib1.
    • Disk devices Device_1 and Device_2 pointing to path D:\MP1 on disk library Lib1 and Lib2.

Unsupported Mount Paths

  • A disk device configured as multiple mount paths on the same library or on multiple libraries. For example:
    • Path D:\MP1 and D:\MP1 on a disk library Lib1 associated with disk device Device_1
    • Path D:\MP1 on disk library Lib1 and path D:\MP1 on disk library Lib2 associated with disk device Device_1

Refer the following support matrix to verify MediaAgent version, platform, paths that support moving mount path:

Source Destination Support
Local Path or UNC Path Operating System MediaAgent Version Local Path or UNC Path Operating System MediaAgent Version
Local Path Windows v10 Local Path Windows v10 Yes
Local Path Linux v10 Local Path Linux v10 Yes
Local Path Windows v11 Local Path Windows v11 Yes
Local Path Linux v11 Local Path Linux v11 Yes
Local Path Windows v10 UNC Path Windows v10 No
Local Path Windows v11 UNC Path Windows v11 Yes
UNC Path Windows v10 Local Path Windows v10 No
UNC Path Windows v11 Local Path Windows v11 Yes
UNC Path Windows v10 UNC Path Windows v10 No
UNC Path Windows v11 UNC Path Windows v11 Yes

Notes:

  • Cross-platform move mount path operation is not supported. You cannot move a mount path from Windows to Linux or from Linux to Windows.
  • Cross-version move mount path operation is not supported. You cannot move a mount path from V10 MediaAgent to a V11 MediaAgent or from V11 MediaAgent to V10 MediaAgent.
  • You cannot run move mount path operations on V9 MediaAgents.
  • To avoid slow data transfer, do not move mount paths between UNC paths.
  • You can move a mount path across V10 MediaAgents that are pointing to V11 CommServe.

Before You Begin

Before you move a mount path, ensure that you meet the following requirements:

  • Review the Mount Path Configuration Support section.
  • Do not move the mount path to the software installation directory.
  • The move mount path operation overwrites the destination mount path. Therefore, ensure that the destination mount path is an empty folder.
  • Ensure that the source mount path has backup data.
  • Ensure that the destination mount path folder is not a subfolder under the source mount path folder.
  • Ensure that the source and destination MediaAgents are online and accessible.
  • Ensure that the destination mount path folder has at least 5% more free space than the source mount path.

Procedure

  1. From the CommCell Browser, expand to Storage Resources > Libraries > library.
  2. Right-click the mount path that you want to move, and then click Move Mount Path.

    The Move Mount Path dialog box appears. In the Select Source MediaAgent dropdown, more than one MediaAgent appears if the mount path is shared between MediaAgents.

  3. From Select Source MediaAgent , select the source MediaAgent.
  4. From Destination Path, select the MediaAgent to which you want to move the mount path.
  5. Select Local Path or Network Path.
    • If you select Local Path, enter the new mount path location in the Disk Device box.
    • If you select Network Path, enter the following information:
      • Connect As: The user name to access the network path
      • Password and Verify Password: The password of the user specified above. These credentials are used by the backup software to access the network share.
      • Folder: The new mount path location
  6. Click OK.

    You can track the progress of the mount path move job from the Job Controller.

Note: If the mount path move job fails or is killed, you need to manually clean the data that was copied to the destination mount path.

Result

After the Move Mount Path job runs successfully, the space on the source mount path is freed up after 24 hours (one day). You can modify the number of days to keep the files on the source mount path by using the Days to keep Mount path files on source location for successful mount path move job parameter in the Media Management Configuration dialog box.

What to Do Next

Perform the following checks after moving the mount path.

  • Verify that the new mount path is online and accessible after the move.

    Note: The new mount path may appear offline if the source mount path has run out of disk space prior to move mount path operation. You will have to wait until the next disk space update to see the new mount path online.

  • You are recommended to perform a disaster recovery backup. See Performing a Disaster Recovery Backup for instructions.
  • If any MediaAgents share the source mount path, modify the path to the new location for all MediaAgents that share the device. For more information, see Modifying the Access Path for the MediaAgents.
