Since past year I'm using Rsnapshot (which uses rsync) to do my daily laptop Linux Ubuntu OS backup to a local NAS.
Some months ago I started having serious problems with the OS stability. It seems like the disk drive gets damaged, so the fsck
needs to be run before boot - this saved me several times over the past few weeks.
I tried to somehow deduce what could be the reason, but no success. Now I am thinking whether it could be that constant daily backups push the SSD drive to it's limits?
How disk intensive is the rsync? Could it lead to SSD problems?
This is what sudo nvme smart-log /dev/nvme0n1
outputs:

nvme
tool, added some info to the question. Doesnum_err_log_entries: 2.890
tell you anything more?nvme error-log
sub command will allow you to display the contents of that error log. Theunsafe_shutdowns
counter may also be an indicator for worry - simply pulling the power from an nvme drive may also cause data loss
