Backup Program In Case of Crash

Question

Hi everyone,

I don't know I'm at the right forum but I've got a question regarding backup methods.
I have a C sharp program and deployed it as an executable.

I would store the db on a server where it is accessible for everyone. So no problem so far.

But...

My program is installed on one computer but imagin my program (not the computer) crashes due of unknown circomstances.
