I have a multi-dimensional backup strategy, which includes “cloudy” backups of my most important assets, using services like GitHub, local hourly NAS (Synology double-redundant RAID-like) incremental backups of my whole system, and running “hot” backups of my system and development volumes; automatically updated every four hours (or on-demand. It's a bootable CCC clone).

I seldom need to use anything more than my “hot” backups, but have occasionally needed to restore individual files from NAS.

Whether or not I have a backup is never even something I think about at all, which is a big weight off my shoulders.

But photos and videos are a different matter from code (my main assets). They require a lot of space. It’s easy for me to be smug about backups; but photographers have a much more intense set of assets.
