Only a client connected to the LU through its Target can access and backup individual files and directories contained in the LU. LUs back up as normal files on a server file system.
CAUTION:
If backing up the iSCSI LU from the server, ensure that the iSCSI initiators are disconnected, or make the backup from a snapshot.

To back up an iSCSI LU:

  1. Disconnect the iSCSI Initiator from the Target.
  2. Unmount the iSCSI Logical Unit.

    To unmount the iSCSI LU, you can use the following CLI command:

    iscsi-lu unmount <name>

    Where <name> is the name of the iSCSI LU.

  3. Back up the Logical Unit to a snapshot or backup device.

    For safety, you should either back up the iSCSI LU to a snapshot or to another backup device.

  4. Mount the Logical Unit.

    To mount the iSCSI LU, you can use the following CLI command:

    iscsi-lu mount <name>

    Where <name> is the name of the iSCSI LU.

  5. Reconnect to the iSCSI Target using the iSCSI Initiator.
  6. If necessary, rescan disks.

    You may have to use Window’s Computer Manager rescan disks to make the LU reappear to clients.
