I use rsync a lot to create snapshot backups, and use hard links across snapshots to preserve space; however, for a single instance backup and unless the filesystem includes hard links (not normal), then the -H won't do much for you. Of course one should always use -a. The biggest concern I have about backing up mail spools is keeping the index and message stores in sync while the backup is taking place. A long time ago someone suggested using cyrdump, but when I looked into this, I couldn't find any documentation whatsoever. Is cyrdump a real thing, or did I imagine all this? ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
