All these techniques are backup. RAID does not have the same purpose.
RAID (with redundancy) is designed to provide availability.
Let me add that mine is a SOHO network that does not require 24x7
uptime. And, since switching to solid-state system drives, I have yet
to experience a system drive hardware failure. My most common failure
mode is instability due to system administration mistakes and root
software development bugs. RAID1 won't help me; recovering from an
earlier known-good image will.
Virtual machine snapshots make recovery even easier.
If/when the Debian Installer supports ZFS boot and encrypted root, I can
install ZFS snapshotting software and will have yet another option.
