Mister save backup script

mister_backup_saves.sh

# Backs up MisTer saves to an external host using SCP, as well as locally for good measure
# Create a special user on the host w/ the specific perms, and use ssh-keygen to generate a key, 
# then ssh-copy-id -p <port> -i <key.pub> <user>@<host>
# don't forget to disable the password on the host after copying
# PLEASE NOTE that the mister has an insecure default password which may be re-enabled on update, so be sure to limit perms appropriately
