I have the problem, that I have to restore every 3-4 weeks my backup on the SD card, because the Raspberry is not working any more. Has somebody else the same problem?
Which kind of SD card are you using? I am using SanDisk Ultra 16GB.
Problem with SD card?
SanDisk Ultra 16GB class 10 (2 years) … “@Gleno0h knocks on wood :-D”

Is your Raspi mounted in a safe place where nobody can touches it accidentally and nothing may hit the Raspi? I am just asking as the SD-Card Connectors of all Raspi Models are flimsy. Just touching the SD-Card may cause failure. That’s even the case for Raspi 3 which does not have the lock mount.
Apart from that it may also be a power failure causing the corruption. Either your system occasionally draws to much power (high load) or it is a short mains power outage or drop out which the PSU cannot compensate - a few 100ms may be enough to kill the system.
