Server Refactoring

So recently my server had some corruption due to a power outage. Clearly I didn’t run any sort of good enough filesystem backups, I just used basic ext4.
I reinstalled ubuntu server 22.04 and restored some services.
I’m still in the process of restoring them, but I am slowly recovering the server’s functionality.
If you have any knowledge of preventative measures for such things, PLEASE TELL ME! I’m begging you. My area has very frequent power outages, and if you could help, please send me an email, I’d greatly appreciate it.

Yeah, thats about it.

Have a nice day.
