SharePoint Server differential backup fails. (4045513)

Date - 06/2008
Affected Product & Version - NetVault: Backup 8.0 U2 and later
Affected Module & Version - APM for SharePoint APM v1.0.13
OS Version - Windows 2000/2003
Application Information - SharePoint Server 2007


Description:
After restarting the NetVault service on a Sharepoint Server differential backups fail.


Symptoms:
Differential backups fail with following error: "A differential backup cannot be started or restored because no full backup exists. You must run a full backup instead."

Restore the last full backup, and move the restored data (spbrxxxx) from the temporary restore file location (by default, $NV_HOME/tmp/nvsprestore) to the temporary backup file location (by default, $NV_HOME/tmp/nvspbackup). Then run the differential backup again.

A permanent solution is to change the location of NetVault's "Temporary Directory" to a location outside the $NV_HOME tree. For example, the Temporary Directory may be changed to "C:\NVTemp". Instructions for reconfiguring NetVault's Temporary Directory can be found in another solution. A new Backup Selection Set will then have to be created for the SharePoint backup jobs.
