Well, kind of special circumstances. Bill explained it fine enough, I think, but... >>I'm not sure what role VSS plays or when it might be used but I would >>need to routinely be able to backup files that are in use. > > > Depends on your definition of "in use".

The most common problem files are, in my experience, outlook mailboxes: They are large, they change a lot, and they are usually locked. With "normal" data files you wouldn't have problems, UNLESS these files are written by the application while Bacula reads them. I don't know if Bacula locks the files it reads (in that case your application would get an error) or if it simply stores inconsistent data (which is the common Unix / linux behaviour). > On the flip side, I've been using VSS to back up Windows workstations for a > few months now with no problems, and all files are able to be backed up no > matter how they're opened. Well, it worked here for a long time, too, but then, without any apparent reason, I got problems with VSS. I started to discuss that on bacula-devel, but since the development FD doesn't even run stable here there's not much I can do to debug this :-( Arno -- IT-Service Lehmann [EMAIL PROTECTED] Arno Lehmann http://www.its-lehmann.de ------------------------------------------------------------------------- Using Tomcat but need to do more?
