Weirdly, reading this had the net impact of me signing up to Backblaze.
I had no idea that it was such a good bargain. I used to be a Crashplan user back in the day, and I always thought Backblaze had tiered limits.
I've been using Duplicati to sync a lot of data to S3's cheapest tape-based long term storage tier. It's a serious pain in the ass because it takes hours to queue up and retrieve a file. It's a heavy enough process that I don't do anything nearly close to enough testing to make sure my backups are restorable, which is a self-inflicted future injury.
Here's the thing: I'm paying about $14/month for that S3 storage, which makes $99/year a total steal. I don't use Dropbox/Box/OneDrive/iCloud so the grievances mentioned by the author are not major hurdles for me. I do find the idea that it is silently ignoring .git folders troubling, primarily because they are indeed not listed in the exclusion list.
I am a bit miffed that we're actively prevented from backing up the various Program Files folders, because I have a large number of VSTi instruments that I'll need to ensure are rcloned or something for this to work.
If you don’t really want backups you can save a lot more money by not signing up for Backblaze.
