A Debian Server stopped responding earlier today. After hardware reset, the data on server was rolled back several months ago to the state it was in february. How is this possible?Everything, logs, webdata, databases, are as if the computer has been turned off on 03. February and turnd on today.
Does anyone know what could cause this? Hacked? How can I prevent this from happening again?
Thanks a lot!
EDIT:
Here is the update what really happened.
On the Server there is a Mirror RAID configuration. One of the HDDs stopped writing data on February 3rd. When second HDD broke earlier today, the system could only boot from the first one. That is why all the data was that old.
Apparently, this is one in the million situation.
EDIT:
So you don't get into same situation as me:
