This one backs up the 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.
