My Backblaze backup has entered some kind of “safety freeze”. Apparently, if you use their client-side encryption, this is an unrecoverable state where they ask that you manually (using their web-based file browsing UI) check the difference between the Backblaze backup and your local system. I have 3 million files and 3 TB of data backed up. That would be … interesting.

After that I’m supposed to manually uninstall, reinstall, and transfer the backup state. There is no explanation for what caused the freeze except a “major inconsistency between the backup records on your computer and the records on the servers”. I haven’t done any OS reinstall, restore from backup or anything really - this came out of the blue.

I’ve used Backblaze for 10+ years with no major issue, so this one snag in a decade of use I can maybe forgive.
