Sorry - that is in purpose ...

The definitive page for rsync snapshots has been, and always will be, here:

http://www.mikerubel.org/computers/rsync_snapshots/

... we actually don't want people to do rsync snapshots anymore because ZFS snapshots are much more efficient and use up less of their rsync.net account.

If you change one bit of a file, the rsync snapshot method will cost the entire size of that file, since it's a hard link and is either broken or not broken.

But if you just do a "dumb" sync to us and change one bit in the file, your ZFS snapshot will take up just one more bit.

So not only do you get a much simpler backup script - you can really just do a dumb sync to us and let us rotate your snapshots - but you get more efficient space usage for changed files.

Thanks for the link and explanations, appreciate it!

I've read that page (i linked) inattentively, re-read 3 times that bold text next to the broken link and still asked that question... :facepalm:
