Follow these steps when you want to backup to another computer that you own. For example, you want to backup a laptop (the source computer) to your other computer called “Desktop.”

The process involves:

1. Installing CrashPlan on a source computer and creating an account (if you haven't done so already)
2. Installing CrashPlan on a destination computer
3. Start backing up

1. Download and install CrashPlan on your computer.
   The set-up assistant will guide you through the rest of the installation. See Installing CrashPlan.
2. Launch CrashPlan by clicking the CrashPlan icon on your desktop (Windows) or in the Dock (Mac).
3. Create an account if you haven't already done so.
4. (Optional) By default, CrashPlan backs up your entire home directory. If you'd like to change this, go to the Backup tab on Laptop and click Change File Selection, under Files to Back Up.

1. Download and install CrashPlan on Desktop.
   The set-up assistant will guide you through the rest of the installation.
2. Click the CrashPlan icon on your desktop (Windows) or in the Dock (Mac).
3. Click Use existing account.
   
4. Enter the email address you used when you created your CrashPlan account on Laptop.
5. Enter the password that you used when you created your CrashPlan account.
6. Click Sign In.
   Now Desktop is available as a backup destination for Laptop (and any other computers in your account) under Destinations > Computers.

1. Open CrashPlan on Laptop and click the Destinations tab. Screen Details
   
2. Click Desktop in the list of computers.
3. Click Start Backup.

Done! Laptop is now backing up to Desktop.
