    Adopting Another Computer

    Applies to:
    • CrashPlan for Home
    • CrashPlan PRO
    • CrashPlan PROe

    Overview

    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.

    Considerations

    Tip: Keep Your User Name The Same
    When replacing a computer, we recommend setting the new computer up with the same user name that you used on your previous computer. If your user name changes, CrashPlan will detect that the file paths for the files in your backup archive also changed. As a result, CrashPlan will back up these changes once the archive is adopted. Even though CrashPlan doesn't back up the files themselves again, backing up the revised file paths can be a lengthy process, especially if you have a large number of files in your archive.

    Before You Begin

    If you are using CrashPlan's upgraded security with a custom key (448-bit encryption with custom 448-bit key), you will be prompted to enter your custom key after adopting your previous computer. We strongly recommend testing your custom key before adopting.

    Step 1: Download And Install CrashPlan

    1. Download and install the latest version of CrashPlan
    2. Sign in to your existing account

    Step 2: Restore Your Files

    1. Restore files that you want on the computer before adopting
      If you adopted before restoring your files, see our guide on restoring after an adoption

    Step 3: Adopt Previous Computer

    1. In the new computer message, click Adopt
      I don't see the option to Adopt

    Click Adopt

    1. Select the computer that you want to adopt

    1. Enter your Email and Password again and click Sign In
    2. Confirm that the adoption completed

    Is My Backup Starting Over?
    After adopting a previous computer, a scan launches to compare the contents of your backup file selection against your existing backup archive. It may look like your files are backing up again, and the estimated time to complete may seem inordinately long. However, CrashPlan uses data de-duplication to identify files that are already backed up. CrashPlan will only back up what has changed (e.g., folder paths if files have moved, new files). This is a normal part of CrashPlan's operation, but if you are concerned, there are several ways to confirm that your backup isn't starting over.

    Step 4: Special Considerations

    There are two circumstances that require special consideration at this point in the adoption process. If neither of these circumstances apply to you, proceed to Step 5.

     

    Different Operating Systems
    If you are moving to a new operating system (e.g. Mac to Windows), then at this point you should proceed to Step 4 of our instructions for Adopting A Computer With A Different Operating System.

    Custom Key 
    If you are using CrashPlan's upgraded security with a custom key (448-bit encryption with custom 448-bit key), you will be prompted to enter your custom key after adopting your previous computer. Entering an incorrect key in the CrashPlan app erases your backup archive. For this reason, we strongly recommend testing your custom key before proceeding.

    Step 5: Verify File Selection

    Once adoption is complete, check your backup file selection to see if you need to add any additional folders. When changing your backup file selection, you should:

    Deselecting Folders (Optional)

    You should only deselect files that you want permanently removed from your backup archive.

    If you have moved files to new folders, and you want to remove the old file paths from your backup file selection, you should do so only after allowing CrashPlan to update the location information for these files. This process is called de-duplication and you must follow the steps below exactly to ensure you don't accidentally remove the files from your backup archive before CrashPlan has a chance to update the location information.

    Important 
    Use caution when deselecting files from your backup selection. CrashPlan permanently and immediately removes deselected files from your backup archive. There is no way to recover deselected files. You will lose any historical versions associated with the folders and files you deselect, even if you allow de-duplication to update the location information for the files.

    If you are not concerned with maintaining historical versions, and you want to remove old file and folder paths, you must follow these steps in the sequence presented:

    1. Verify that the new location for the files is included in your backup file selection.
    2. Keep the original file location selected. Do not deselect any files at this time.
    3. Allow your backup status to reach 100% complete.
    4. It is now safe to deselect the old files and folders. You can restore these files from their new location on your new computer.

    Note: When you change the backup file selection, a scan launches to compare the contents of your backup file selection against your existing backup archive. While on the surface it may look like CrashPlan is starting your backup over, this is a normal part of CrashPlan's operation. There are several ways to confirm that your backup isn't starting over.
