What is the best way to backup a home server (Ubuntu 14.04)?

Question

Backup

The farm has a home server running Ubuntu 14.04 which is responsible for several tasks:
- file server (Samba)
- torrent download (Transmission)
- personal blog hosting (nginx + php + Wordpress + MySQL)
- media server (minidlna)
- video surveillance server (motion)
Setting up all this economy is carried out via SSH
I want to set up a backup, but not just make a complete image of the system, but only the necessary configuration files responsible for the operation of the above services.
How to make such a backup? Write a script or have a ready-made solution?

Answer 1

With scripts, you basically only need to back up /etc/mysql and the sites directory. I think the volumes are small, set up something like rdiff-backup + mysqldump and you will be happy.

Answer 2

Look towards the puppet
