IDrive keeps up to 30 versions of files indefinitely, which means if you delete a file on your local storage drive you can (theoretically) pull it up years later in IDrive. IDrive is a little clunkier to use than Backblaze, but it’s more flexible, with more options for you to change how IDrive works than Backblaze has. However, IDrive allows you to back up multiple computers for that price, something Backblaze doesn’t do.
At $80 a year for 5 TB of storage, IDrive costs more and stores less than Backblaze.
