TIL there is actually a ruby gem devoted to streamlining backups!
See http://meskyanichi.github.io/backup/v4/ for more details.
I haven’t explored it at all yet other than looking at the webpage, but it looks extremely promising. There are tons of features!
Of course, automation is what makes this even cooler – and there is a puppet module for that – see evenup/backup at Puppet Forge.
I am really looking forward to trying this out!
