You can use other computers you own to create a convenient onsite backup destination. Backing up to other computers is always free, with or without a subscription to CrashPlan for Home.
In this example, we back up Marvin's Mac to Marvin's Windows Desktop.
If you would like both computers to back up to each other, repeat Step 2 from your other computer.
By default, CrashPlan uses as much storage space as needed for the archive.To limit the amount of storage a computer on your own account can use:
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.
