Yeah third party program can be used, I don't think they have anything internal to manage this.  
 
On your control panel where you start and stop your server, you should see something like this
It's just copy the info you have on your side here into the filezilla :)

No problem
 
I took everything from the FTP site listed here.

 
And later uploaded everything back into the server after the reinstall (there is an option to reinstall the server in the control panel)
 

At first I wanted to take folders with the name "Save" and "Saved" but later decided against it and just took everything  I probably didn't need to, but I just didn't want me and any other person on my server to start over.  

I'm using the custom restart for every monday (hopefully this works) right now after my reinstall I haven't had issues with the server just randomly shutting down (at least for a day now) It usually happend every night at 2 AM. now it keeps running and running smoothly.

I backed up everything from the server using FTP (Filezilla) and then reinstalled the server, after that I uploaded all the save files and such again. now it runs even better than before.
I had the same issue with the server stopping the minute I connected.
I assume it has an issue with not clearing it's cache logs or something? Might be why after a couple of days of uptime that it crashes.

Thank you I decided to turn it off as well and haven't seen a restart but to early to be certain, thanks for the extra input you giving!
