We're using Data Protector A.06.11, I'm running into a problem with one of my backups this week. I have a job where it is backing up four Network Shares using one cell manager. For some reason over this past weekend one of the shares started receiving the "Not a valid mount point" error 81:52 (The filesystem mount point specified by the user is not a real mount point on the system running the VBDA agent) and aborted. The other 3 shares backed up just fine with no problems. The only thing that happened is that my boss totally re-arranged files and folders within this one share (deleted some, moved them out, renamed a few, and created new ones) which I'm sure is the cause of the problem. I've tried recreating the job but still receive the same error. The Actions says to " Verify the configuration of the backup object and the table of mounted filesystems on the host running the VBDA agent" - how or where do you do this at. Where is the VBDA agent? The cell manager is on a Windows 2003 system but the network share is a CIF and does not contain a real OS. Any ideas as to how to correct this?
