Simple backup to external device

This just sync any folder with an external device by using crontab. It's meant to run sparsely, hence it mounts and unmounts the device on every execution.

It consists of two scripts:

with_device.sh: mounts and umounts the external device - should be in a folder with restricted access
simple_backup.sh: does the actual backup using rsync - can be in any folder

Crontab sample:

	/* ---------- General Helpers ---------- */

	function _sort_idxs(items) {
	return items.map((item, idx) => [item, idx]).sort().map(i => i[1]);
	}

	function _sort_apply(idxs, items) {
	return idxs.map(idx => items[idx]);
	}
