You can't. I've a similarly "unknown" set of files to back up and the best I could come up with is run find on the client looking for files not modified in the last 24 hours. And even then bacula isn't saving the metadata (ownership, permissions, timestamps) on parent directories (apparently it's a feature). So if you know these files don't stick around for more than X hours, you can run a script on the client that gives you a list of files older than X hours & you back up those. Obviously, that gives you a X-hour window when "real" files aren't backed up plus a change for false negatives & false positives. Plus bacula's dynamic fileset "feature". We also have a rule: anything with "_unb_" in its name isn't backed up -- but I can educate my users... -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
