New files disappear when restarting power

[blackPanter28]

Hello everyone. I'm new to Armbian.
If I do not restart or turn off by command (correctly) all the files generated or transferred since it was turned on are deleted immediately.
Why?  Is it normal in Armbian? I use Orange Pi Win Plus 2, how do I deactivate that functionality?

I use it as a remote server.

All files changed in last 10 minutes. That would be normally. If more than 10min, your SD card is dead.

 Do a proper shutdown. If you want to avoid fs corruption in any stage, you need to have full read only file system. This is ofc possible, but it has other limitations - you can't write to it  

You can change commit interval from 10m to 0m but it will affect performances. Go to /etc/fstab and remove commit=600 but this will solve only one problem. You still can run into fs corruption due to sudden power cut.

The same reason as for a Windows machine that you should NOT unplug the power cord without proper shutdown, otherwise you are searching for OS corruptions ...
