If you have a Mac, get an AirPort Time Capsule. This gives you automatic, hourly backups.
If you're here, get a Tarsnap account. This gives you backups however you script them. They're versioned, deduplicated, and NSA-resistant.

And while I've got your attention, 1) are Arq backups encrypted and 2) can it back up via SSH to my own storage somewhere - like a cheap VPS with lots of disk space?
2) Yes. Although if you're after cheap space, Hetzner's storage boxes are the cheapest $/GB I've seen (https://www.hetzner.de/hosting/produktmatrix/storagebox-prod...), with Backblaze B2 close behind.
Compare that to Backblaze or CrashPlan, which do all your PCs for $5/month.
