This makes the cost-per-backup just the incremental cost of changed files; unchanged files are thus hardlinked from the previous backup. Code here: http://www.cskk.ezoshosting.com/cs/css/bin/histbackup Then: mkdir -p /media/500GB-Drive/backups histbackup -x / /media/500GB-Drive/backups -X Histbackup automatically honours a .hbinclude file in the backup area as an '--include-from' option, so you'd set up /media/500GB-Drive/backups/.hbinclude as required. There's a bunch of similar rsync-based backup scripts on the web for this purpose.
