I'm busy re-working how I handle backups of my personal files. A very useful recent discussion on some available features and technologies is at Theodore T'so's blog: http://thunk.org/tytso/blog/2009/01/12/wanted-incremental-backup-solutions-that-use-a-database/.

From that post I discovered a package 'archfs' which provides a FUSE-powered filesystem view of an rdiff-backup history. I found a stale ITP for this package and have adopted it, so keep your eyes out for that.

Looking at how I am going to approach things, I think the Debian package of anacron might need some work. I'm planning on looking at the issues there a bit more closely and feeding back to the maintainer when I do.
