Challenge
Getting the message "File is locked by running session (Name of Current Job)"
Cause
If the job was stopped incorrectly or the Veeam Server was rebooted, SQL might not have had enough time to receive the queries to properly stop the job in the database.
Solution
Please make sure no jobs are running before doing the following:
Run the following SQL Query against the Veeam Database:
delete from [Backup.TrackedActions.Leases]
delete from [Backup.TrackedActions.LockItems]
delete from [Backup.TrackedActions.Locks]
