If you want to start a new 10 year uptime journey and be able replace SD-card without reboot, make the root filesystem Btrfs instead of Ext4. Then you can also pro-actively check for block-level corruption ('bit-rot' on HDDs) via btrfs scrub command, is done in the background. I did some auto-conversion on new trixie images, see viewtopic.php?p=2336089&hilit=btrfs+convert#p2336089I´ll bet that if you power down and up,the SD will be corrupted...... I used to have a couple of RPI3.1B running continuosly to deliver me the location IP as well as a sort of watchdog to detetct that the remotes sites had lost power. After a few months, the SDs were corrupted and had to replace them by the backup one. Despite the SD being corrupted, they were working until the AC power went off and on....
Can also be achieved via other steps or methods, like rsync to extra partition first, that is what I did long time ago for my RPi1. Some OS like Armbian can generate a new image with rootfs Btrfs (note: only 64-bit for RPi devices).
