At VA Hosting LLC we do our best to protect your files/server
It is always a good idea to back up your files, no matter how much we try to protect your files there is always a chance that something can go wrong.
To back up your Minecraft server use a program like FillaZilla to download your server files to your computer, for information on using FillaZilla see this article: https://vahosting.net/knowledgebase/11/How-to-use-Filezilla-with-VA-Hosting-LLC.html
What happens to files after the service is canceled
After a service is canceled, all the files for that service are deleted and cannot be recovered. If you plan on cancelling your service but still want the files, be sure to download the server files before cancelling the service.
