The data migration connector will not help much in cases where your laptop and your local backup disk are destroyed.

My setup backs up to both local and networked disks (both disks listed in Time Machine, so backups alternate between them). The networked disk is actually a folder in a Debian VM that, from time to time, sends the backup to AWS.

A bit paranoid, but little added effort (figuring out and setting everything up took about an afternoon).
