Backblaze

Backblaze will automatically back up all your files including documents, photos, music and movies.
It takes security seriously.

All data is stored in our secure datacenters with 24-hour staff, biometric security and redundant power. Backblaze has enabled two-factor authentication. Now a 6-digit code can be sent to your phone during sign-in for an extra layer of security.

You can use a personal encryption key for additional security. If you lose your password, Backblaze will be unable to send it to you.
