The thing is the only real backup solution which worked for me was clonezilla. Offline backup of a complete drive. But it is too much work. Its offline, it takes time etc. But at least i have a known working state which i can restore onto and have everything. I would need a live clonezilla backup onto a network drive and a bootloader, which has functionality to restore that backup.

Someone above mentioned Veeam, which I love for windows, but haven't really tested on Linux. It's free, but not open source.
I personally use rsync to btrfs, but it's not encrypted.
