SQL error after backup (76863)

When the backup took a Quiesced snapshot the database on the SQL server that was being backed up stopped working.

The work around is to:

1. Restart the database
2. Change the time of the backup to a time when no one is using (no maintenance is being performed) the database

Run the backup again.

Things to check:

1. Is the database compliant with Microsoft VSS
2. Is there a BackupExec agent installed on the server

If it is installed:

1. Uninstall the agent
2. Reinstall VMware tools on the server

Run the backup again.
