On the newer 16M flash devices, if you do not write your files into the flash folder, they will be erased on reboot, since the file root is a ram drive.
You can do this in winbox after doing the backup in the file window, by drag and drop of the file onto the flash folder.

There are least two way to get backup out of Mikrotik automatically.

  1. Make a script that sends you periodically en email with your backup.
    You can use gmail as a relay server to get your email.

  2. You can use SSH from a linux server to grab files or other info from your Mikrotik periodically.
    For this you need a linux server
