Backblaze Personal Backup review

Backblaze Personal Backup is the most direct answer to the search for unlimited cloud storage. For $9 a month per computer it backs up all user-generated data on a Mac or PC and on connected external drives, with no restrictions on file type or size. The app is native to Mac and Windows and runs in the background once installed, so there is little to configure. Restores are where it stands out for heavy users: you can download from the web in zip files of up to 500 GB per request, use the iOS and Android apps, or order an encrypted USB drive that is refunded when you send it back within 30 days. Security covers two-factor sign-in and an optional private encryption key. The limits are clear. It is a backup, not a sync drive, so you cannot work from shared folders, and each computer needs its own license. Longer version history costs extra.
