1. I keep working data on my laptop, and archived data/media on a desktop machine in my home. 2. Both are backed up to Time Machine to a network drive, and also with Arq to Glacier. 3. I keep important documents in Dropbox. This gives me "Oh shit, I deleted a file" protection from Time Machine and Dropbox, two local copies of all media and data in case of hardware failure or machine loss, and a last-ditch offsite Glacier backup. Works well, and Arq isn't that pricey if using only Glacier.
