Error Message

“Operating System not found”

Scenario:

1.       Run a full backup of a VM and then run few incremental backups of the same VM.

2.       Perform an Instant Recovery of the VM using any of the incremental backup set.

3.       Perform a restore of the VM using any incremental backup set.

4.       Remove the Instantly recovered VM from Backup Exec using the “Remove a recovered VM” option.

5.       Perform Instant Recovery of the VM, by selecting a different incremental backup set this time.

6.       It is observed that the Instant Recovery job completes successfully in Backup Exec, however the VM remains in-accessible from remote console or the VM administration/management console (like VSphere Web Client etc.). The VM in this case does not boot up and shows Operating system not found error on the command prompt.

Workaround:

Option 1

1.       Remove the Instantly recovered VM from Backup Exec using the “Remove a recovered VM” option.

2.       Re-run the same instant recovery job of VM and access the recovered VM.

Option 2 (if Option 1 does not work)

1.       Remove the Instantly recovered VM from Backup Exec using the “Remove a recovered VM” option.

2.       Restart the “Backup Exec PureDisk Filesystem Service”.

3.       Re-run the same instant recovery job of VM and access the recovered VM.
