A SharePoint Backup Operation Fails

Article ID: SP0006 A SharePoint backup operation fails.


A backup operation fails with the following error in the CVSPBackup.log file:

The specified network name is no longer available.


If a virus scanner is running on a SharePoint server, then the virus scanner might delete staging files or network shares, causing the backup operation on that server to fail. 


On the SharePoint server, either disable the virus scanner or exclude Commvault processes from the virus scanner configuration.
