This tutorial explains how to back up to a friend's computer. Backing up to a friend gives you the advantage of off-site protection, and it's free!
- CrashPlan app: Your friend must download the CrashPlan app before you can begin backing up to their computer.
- Accessibility: Your friend's computer needs to be powered on when you want to back up or restore files.
- Speed: Because backing up and restoring takes place over the Internet, the initial backup and a complete restore could take a while. You can reduce the time required to back up by "seeding" your backup locally.
- Security: Your friend is not able to see the files you have backed up. Even though the backup data is stored on your friend's computer, it is encrypted and can only be accessed when you sign in with your account information. Likewise, you are not able to see your friend's files.
Follow these steps to begin backing up to a friend's computer.
- Ask your friend for the Backup Code that appears on the Friends tab.
- Open the CrashPlan app, and go to Destinations > Friends.
- Under Back up to a friend's computer, enter your friend's backup code.
- Click Start Backup.

If a friend starts backing up to me, can I also back up to my friend?
Sharing your backup code with a friend does not automatically allow you to back up to your friend’s computer. To allow backup, your friend can either:
- Give you his or her backup code.
- From the CrashPlan app, click Friends. From the list of friends, select your name. Then, click Allow this friend to back up to this computer.
When your friend's computer is offline, the connection between your computers is disconnected. Your computers can be disconnected at any time, and for any length of time—CrashPlan won't delete the files. When both computers are online, your backup will reconnect, and CrashPlan resumes backup from where it left off.
Your backup is stored in a folder labeled with the 18-digit computer ID that corresponds to the computer being backed up. The folder contains all of the elements of your backup in an encrypted archive format.
If a drive becomes too full for CrashPlan to continue backing up to it, the CrashPlan app reports Out of space at destination. To continue backing up, you can either move the backup archive to a larger drive, or reduce the size of the archive. Review our troubleshooting article for full details.
