I have a cheap 2 bay synology NAS that acts solely as a backup server for my main NAS in an offsite location as well as a USB drive locally.

Backups run every night with duplicacy

I exclude media files (movies, TV shows,…) from my backup routine due to the sheer amounts of data accumulated over time and the fact that most of it can be re-aquired using public sources in case disaster recovery is needed

Definitely an interesting project especially for those Linux users that mostly stick to one machine and like to experiment with new features.
For the regular sys admin type of person that needs to jump from one Maschine to another it’s probably a little too non-standard and hard to get productive with

Many Linux users spend a considerable amount of time using the command line interface, so the right shell configuration can make them much more productive.
