How to back up to another computer you own:

If you own more than one computer, backing up between them is easy. Remember, if you're not backing up off-site, you're not backing up. In fact, it's best if you're backed up off-site to at least two locations!

  1. Install CrashPlan on the second computer just like you did on your first computer.
  2. Instead of selecting "new account" make sure you click "existing account" and enter the same e-mail address and password you used when installing the first time.
  3. Don't worry about the free trial message. Allowing others to back up to you is free. This feature will continue to work after 30 days.
  4. Permission to back up from one of your computers is automatic. So at this point your second computer should automatically appear as a destination on your first.
  5. If the dot is green, you're connected and ready to back up. If it's gray, that means they are having trouble connecting. While CrashPlan is very good at automatically finding a way to connect, sometimes manual configuration of your personal firewall or router is required. CrashPlan needs access to TCP port 4242 at each computer.
  6. Press "Start Using" to begin backing up to your second computer. If you have a lot of data to back up and one of them is a laptop, consider bringing the laptop to the other computer and backing up locally first. It's much faster.

Congratulations! You are backing up to another computer that you own!
