Hi, I am working on a client site trying to troubleshoot some backup issues. They are running BEWS 12.5 with CASO and shared storage option. All catalogs are stored on the CASO server only. Backups on their main file server (Windows 2003 Standard) are completing successfully but further investigation has shown that only the folder structure is being backed up and not the individual files. This is only true for some of the volumes being backed up - others are OK. They are using VSS as their open file option which I suspect may be the root of the problem. Has anyone got any ideas? Thanks in advance, Neil.
