To back up remote my Linux hosts, I use a tool called rsnapshot. This utility is a wrapper for the venerable rsync (Think robocopy on steroids if you’re from the Windows world) and leverages SSH as a secure transport mechanism. It can be run both locally and remotely.

While Salt is the swiss army knife of configuration management, I had a somewhat trivial task to accomplish - deployment of config files. Using a centralised point such as Pillar or the Salt file system along with Salt’s templating tools, it’s simple to distrbute dynamic config files and get that warm & fuzzy feeling of never having to connect to a remote host again.
