I have been advise by Commvault partner support to turn off the backup of the master database as the backup failed due to the log file being lock.
The following is the advise given:
"The message is caused by Commvault’s inability to backup the master database’s transaction log.
If this is happening intermittently its possible that something is locking the transaction log, preventing SQL iData agent from accessing the log.
Typically the master database is just a template and is not used by any applications (applications that do require the use of an SQL database create their own) so there should be no harm in preventing it from being backed up
You can do this by nominating NOT to back it up in the primary copy for the SQL data agent"
The following is the error that I get.
