It's a good discussion. I've taken a different path but with the same ideals. 1. All my live, working data is in Dropbox. I've been using my (paid) Dropbox account for over a decade. This step isn't really intended to be a backup per se, but you get the backup behavior "for free" because this is how I keep my secondary machine in sync with my primary. My Dropbox folder is also replicated to a 3rd computer in my home as another level of redundancy. 2. Everything in my home dir, especially photography, is ALSO covered by Backblaze. Having some backups elsewhere is mandatory; not enough people really understand how important this is. Should my house burn down, I still have data. 3. My primary system is a Mac, so I use Time Machine. TM is the only backup on this list I've ever actually used as a backup. When our home was robbed a number of years ago in a quickie smash-window-and-grab affair, they got my laptop. I went out and bought a new computer, plugged it into the TM drive, and in an hour or so I was right back where I left off. Hard to beat that. Even my app windows were in the same place. 4. Periodically, I take a full clone of my main machine's drive using a drive imaging tool (Mac specific; I use SuperDuper) and **store that drive at a friend's house**. This probably only happens a few times a year a this point. I should do it more often. That tertiary computer I mentioned in step 1 is also the home NAS server / home media server. It holds the photo archive in a large outboard disk. Backblaze covers that disk, and Time Machine on that computer keeps the outboard disk backed up as well. This data is mostly static, so the images I've taken of it and stored elsewhere don't need to be updated all that often (ie, just when I migrate prior year photo data to that drive).
