I'm trying to restore a file from tape using ARCserve 2000. According to the log, the file was backed up successfully, but when I try to restore it I get the message "Error N3941 Skip File - File marked as invalid" and the backup job cancels. I really need this file, but CA didn't give me any hope of getting this one off the tape. Does anyone have any idea how to get this one back? There might have been some corruption of the file on disk prior to backing it up.
