Problem with Back up of open/locked files

I am trying to back up a .mdb that is open by a software program. When the program is open the file is not backed up. I tried both VSC and Raw Read both with ignore read errors and with out. As soon as the program is closed and the file is unlocked Comodo back up can back up the file. I am using Version 4.1.2.28. The error message in the log is

Please let me know if there is anything I can do to get this to work. I am very pleased with everything else that this software does.

Hey, i have exact the same problem. Did you find a solution for that?

I need to backup a locked file using vss without administration rights, how can i do that?
