Request for automated backups of config every x days for 2-3 days

Request for automated backups of config every day for 2-3 days (or trigger when its a new day and config is changed?) Can just happen in background and give a user a manual way of restoring if something happens

Added cron jobs for uptime, so ill make a cron job for this as well.

actually this should be done by an external process. eg if using unRAID can use appdata backup plugin. in the dotnet rewrite, theres only 3 files to backup.

• Fenrus.db
• encryptionkey.txt
• key-{guid}.xml (if exists)
