This one backs up the
[Alpine Local Backup](https://wiki.alpinelinux.org/wiki/Alpine_local_backup)
to my big storage array.

My system runs from a RAM disk,
which means whenever it reboots,
it loses any changes I've made.
Alpine Local Backup is a mechanism for stashing these changes away to persistent storage.

The backups Alpine makes are compressed tarballs.
`tar xzf backup.tar.gz` will restore everything it's saved.
