Won´t boot after power breakdown

Hi everyone, after a power break, my HA (Rpi3B+ with SSD) did not restart. I then reinstall and made a backup from a snapshot. Worked great… until the power company decided the day after to make another power break. Then I am back on a non working HA… Not so much work to make a fresh install and put the snapshot back. But something is obvious incorrect in my files? So, what part should I take (or not to take) from my snapshot, so that my system will work and boot after power breakdown in the future?

Or, can I fix the problem without a fresh install?

Since you did not have the Pi protected by a UPS to shut the system down orderly, you would likely need to make a fresh install. It would be best if you use a copy of a snapshot stored somewhere else. The filesystem on a Linux system may be inconsistent and have errors after an unclean shutdown.

Did a snapshot reinstall. Had to make a power break again. To be safe I shutdown core. Waited. Then close the power. But same shit again. Does not boot. I assume something is wrong with boot setup… can I exlude something from the snapshot next time to fix this?

You did not shut down the OS and the many processes running there.
