If the backup was created as part of Strategy-1, upgrade the current OCSM server with release 4.x or 5.0 to Release 5.1. For more information, see the Session Monitor Release 5.1 Upgrade Guide.

If the upgrade is successful, then there is no need to restore anything. However, if there is an issue in the upgrade procedure, and the existing data in the machine is lost, (for any reason), follow the instructions given here to restore data from the remote disk or the shared drive.

If the backup was created as part of Strategy-2, then a freshly installed OCSM server already has all the necessary block storage data. So, in this case, block storage restore procedure is not required.
