[SGVLUG] Dev-sig location

[Eric Hammond]

For backups, I use dirvish which is also based on rsync and hardlinks.

  http://www.dirvish.org/

Dirvish configuration files are a little confusing at first, but once
they are set up, it works like a charm and has very flexible expiration
/ rotation rules.
