Adopting another computer is the process of having one computer take over for another computer that has been lost, stolen, sold, or reformatted. This process also applies when rebuilding your computer following a crash. By reconnecting to the previous computer's backup archive, you avoid repeating the potentially lengthy, initial backup.
The adoption process is an optional operation available when CrashPlan detects a new computer is accessing the CrashPlan app under an existing account. Adopting allows the new computer (or rebuilt computer or drive) to use an existing computer's backup archive, backup file selection, and backup settings. It also deactivates the other computer so it can no longer back up.
Adopting another computer should be used when you are:
- Reformatting a hard drive
- Upgrading your operating system
- Setting up a new computer to replace one that was lost, stolen or sold
Before You Begin
- Restore your missing files before choosing the adopt option.
We recommend restoring your files before adopting a previous computer's identity because the CrashPlan app automatically synchronizes your file list with what is currently stored on the destination. By restoring your files before adopting the new computer, you prevent CrashPlan from thinking the files are missing and subsequently marking them as "deleted". However, it is okay if you adopt before restoring. Your backed up files may be hidden, but they are still recoverable
- The adoption process deactivates the original computer and no longer allows it to back up.
- If you are not switching to a new computer, first uninstall the CrashPlan app to remove all traces of the old CrashPlan app on your computer.
WARNING: If you are changing computers, make sure the computer with the old ID is no longer in use or connected to CrashPlan Central.
- Changing operating systems: If you are moving to a new operating system (e.g. Mac to Windows), then you should follow the instructions in the Cross-Platform Adoptions article.
- User folder: When you install your operating system for the first time, you will have the option to name your home directory. To make the restore and adoption process seamless, use the same name for your primary User that you used on your previous computer.
WARNING: After reconnecting, do not deselect files from your backup selection. CrashPlan immediately removes the deselected files from your archive. You do not have a chance to confirm this operation. There is no way to reverse this operation or recover these removed files. Learn more about deselecting files

The Adoption Complete! message should display
- After adoption is complete, verify your file selection to ensure that any files that may now reside in a different location on your system are selected for backup.
After adopting, do not deselect files from your backup selection. CrashPlan immediately removes the deselected files from your archive. You do not have a chance to confirm this operation. There is no way to reverse this operation or recover these removed files. Learn more about deselecting files
"But what happened to my original backup? I don't want to start over again!"
After you adopt, the CrashPlan app performs a full file verification scan, which compares the data on your computer against the data on our servers. This scan looks like it is backing up your data again, but will go much faster.
This is done to ensure that we have an exact copy of what you have on your system and is a regular process of the software. While this is running, you can still go to your My Account page to restore files and view the data in your archive.
