Filesystem restore hangs from SmartDisk and hasn't anymore relevant information after the following Binary Log entries:

Job Message 2011/12/05 10:04:08 1435 Media BACKUP_SERVER Job has been assigned device 'SmartDisk - 10.128.81.11'

SmartDisk 1.5.1 is only supported to work with NetVault Backup 8.6.1 as per our Compatibility Guide on our website:

https://support.quest.com/NetVault Backup

Performed the following steps to resolve the issue:

1] Perform a NVDB backup - which should be done on a daily basis and not when other backups and restores are running.
2] Upgrade the NetVault Server to 8.6.1 (or above).
3] Upgrade the NetVault Clients as well.

Note: Please reboot the machines if installed on Windows.
