On: Rediscovering the Rsync Algorithm

[ajays]

rsync is great. I use the "-H" and "--link-dest" options to make incremental backups which look like snapshots. Been doing this for the better part of a decade; would be interested to know if there's A Better Solution(tm) out there...

rdiff-backup http://rdiff-backup.nongnu.org/ may be what you are looking for?

rsnapshot, which does all that for you with automated rotation, built on top of rsync.
