We needed a better-effort way to get most message for a disaster. <div><br></div><div>I looked for the patch a bit ago (not that it would apply, but I would at least see what I had changed!) but couldn’t find it. I haven’t been employed by that organization for just over 8 years now, so it’s nowhere in my cache. <div><br></div><div>The general point of my comment was: If you’re backing up files, looking for them is expensive. If you can get Cyrus to tell you what it changed, then you don’t have to ask the filesystem — which usually involves asking every file. The other option would be to use a filesystem that supports DMAPI, and write a DMAPI application that kept track of changed files and added them to a backup queue. It seems like having Cyrus log the delivery would have other benefits, though, and would work on any filesystem. I’m not currently a Cyrus admin, though, so it could already do that for all I know. :)</div><div><br></div><div>Liberty,</div><div><br><div>

<div>You could easily stop the replica and take a snapshot of that, but our real backup solution is much more evil. I've posted it to this list before, but it's basically a perl daemon which knows far too much about how Cyrus locks its data files. It actually reads and parses cyrus.index files to work out what it needs to do.<br></div>
