I used to use rsnapshot, which is not much of a conceptual step up from rsync, and thus is an easy tool to use, but the architectural decision to keep hard link trees for each increment caused me a lot of problems for large mailboxes (lots and lots of small files; high ratio of filesystem metadata to actual data). Deleting old increments was very computationally expensive. So instead I use rdiff-backup. It's a very similar tool but it uses a more clever scheme for storing increments. The most recent increment is available as simple files, and most restores are of the last backup. The scheme it uses for increments is quite simple, well documented and third party tools exist to manipulate it, which gives me confidence. -- Jonathan Dowland Please do not CC me, I am subscribed to the list.
