I've seen some interesting comments in this thread so far, but none seem to discuss our concerns: We have a fairly large installation, and due to the file-per-message nature this makes for millions of small files which can wreak havoc on a backup system. We're using VXFS on Solaris, but are using a homegrown hodgepodge of stuff to get reasonable backup performance, and our trust in this solution is not terribly high. I'm curious how others have addressed the situation? We have not even attempted to set TSM or any other commercial backup software loose on the mail server yet because of the incredible index requirements.
Is anyone successfully implementing any sort of incremental backup solution in a large production environment? Steve
