At least 2-3 times per year Backblaze goes into a safety freeze, and the only way to unclog the works is reinstalling+inheriting the backup. Which involves re-uploading every single file.
Would not choose Backblaze if I was choosing today.
Due to the safety freezes and the high expense of Backblaze when backing up multiple machines, I have switched to iDrive. So far it seems to be working ok.
