Yeah, unfortunately our enterprise backup solution is TSM, which is good for just about everything but Cyrus. (It keeps a database with an entry for every single file, which with Cyrus's tens of millions of files, really doesn't work well.) We'll probably end up doing something with tar and either TSM or our new VTL infrastructure, but I was hoping someone had some prebuilt scripts or something cool that would take care of it. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
