[Discuss] Cloud backup

[Rich Braun]

Check out Duplicati, https://www.duplicati.com/. It works about like CrashPlan (the service withdrawn from home-user market a couple years ago), allowing you to define retention schedules and maintain a full history of modifications file-by-file. It can send the files to most any online storage service of your choice. Over the past year, its open-source developers have done a lot to stabilize it.

Rsync by itself just makes a single copy of files so if you don't detect loss before the next time it runs, you're out of luck. That's why I use rsnapshot as my preferred secondary backup method.

I always use two backup methods these days because undetected failures are laughably common (and not fun at all when you're trying to recover a file that didn't get backed up because of a neglected setting, software update, API key or any of dozens of other possibilities).
