You can get remarkably good compression by using xdelta3 on dump
files.  I have almost two years worth of *daily* backups and they
consume only 10x the space of the active data itself (and lives on
much cheaper/slower storage).

I should probably only keep monthlies, but I haven't gotten around to
adjusting the scripts.
