Backblaze Computer Backup review

Backblaze Computer Backup is built for people who want offsite backup to run without decisions. After install it backs up all user-generated data from the computer and any connected external drives, with no limits on file type or size and no storage cap, for $99 per year per computer. The client is native on Mac and Windows and backs up continuously as you work. Restores come three ways: the web, the mobile apps, or a USB drive mailed to you, which is refunded if you send it back within 30 days. Web restores are prepared as zip files of up to 500GB each. Security covers a default public and private key scheme, an optional private encryption key that only you hold, and two-factor verification. The trade-offs are the per-computer price, which adds up in a home with several machines, and the lack of a Linux client. Longer version history is available, but Forever retention is an extra fee.
