Hello,
Please refer to these technotes to have more inofrmation about the Advanced Open file option:

1. With Lock : Select this option to have Backup Exec attempt to open files that are in use. If Backup Exec is able to open a file, the file is locked while it is being backed up to prevent other processes from writing to it.
Backing up open files is not as effective as closing applications and allowing the files to be backed up in a consistent state.
2. Without a lock : Select this option to have Backup Exec attempt to open files that are in use. If Backup Exec is able to open the file, the file is NOT locked while it is being backed up. This allows other applications to write
data to the file during the backup operation.
Hope this helps!
