Learn what is backed up
Backup Online
Whether directly connected or over WiFi, If you are connected to the Internet, you are backing up.
Backup Continuously
Files change and Backblaze backs them up. By default, Backblaze simply backs up all the time so you don't have to remember. But if you wish, you can schedule Backblaze to backup at a convenient time or only when you click "Backup Now".
Backup Securely
Your data is encrypted on your computer, sent over an encrypted connection, and stored encrypted. Want more security? You can use your own private key so nobody but you can ever have access to your backups. Want the nitty gritty?
Read our blog post about backup encryption.
Backup External Drives
Use a USB or Firewire-connected drive for additional storage or backups? Backblaze will backup those too.

Backup Fast
Backblaze has developed a unique 'single-read' engine that ensures no slowdown of your computer. Backblaze provides an automatic throttle that most efficiently uses your Internet connection. Typical home connections can backup online 2 - 4 GB per day. Backblaze provides a throttle option if you want to use more or less of your Internet connection. Check your Internet connection:

Backup Efficiently
Backblaze de-duplicates, compresses, and backs up incrementally to backup online as efficiently as possible. Have the same photo stored twice? Backblaze will de-duplicate to back it up just once; if you restore, it will be put back in both places. Have some large files? Backblaze will compress them when possible. Change a file multiple times? Backblaze will only back up the changes.
