Adoption is the process of having one computer take over for another, which is used in circumstances such as: moving a backup to a new computer, replacing an old computer, replacing your computer's main hard drive, or recovering after an operating system reinstall. By reconnecting to the previous computer's backup archive, you avoid repeating the potentially lengthy, initial backup.
When replacing a computer, we recommend setting up the new computer with the same user name and drive letter that you used on your previous computer. If the user name or drive letter on your new computer is different than on your old computer, you may need to update your file selection to include the new location of your files. CrashPlan can then synchronize with the destination and continue backing up files that now reside in a new location and have a different file path.
Before you adopt a computer, it is important to replace all of the files you backed up previously onto the new computer. When adopting, CrashPlan looks for your files at the location they were on the old computer. CrashPlan needs to see the files on the new source computer in the same location as the old computer, so that the files are not marked as deleted and are not re-sent.
Before adopting, you can use any of the following methods to replace your original files onto your new or re-built computer:
Now it's time to adopt your previous computer so that CrashPlan sees your new computer as a continuation of your previous computer. When you adopt, your new computer:
If the previously backed up files are not restored to the computer before adopting, you may have an extended wait to restore your data while CrashPlan synchronizes your computer with the backup destination. Any files that cannot be found during synchronization will be flagged as "missing" and you must follow these steps to restore them.
Once the adoption is complete and all previous settings are applied to your new computer, verify that your file selection includes all of the files you want to back up. If you restored your files to a different location (for example, under a folder with a different user name or drive letter), CrashPlan does not automatically detect the change in file paths. To continue your backup, update the file selection to add the locations of your files on the new computer (without deselecting the old locations) using the steps below.
After you add folders from your new computer to your file selection, the CrashPlan app synchronizes your file selection. It detects the files you restored to your new computer, and recognizes them as the same files you previously backed up from your old computer. Any new files added to your selection are analyzed and prepared for backup.
When synchronization completes, you may choose to clean up your file selection by removing the old "missing" locations of your files.
If you are not concerned with maintaining historical versions, and you want to clean up your file selection by removing the old file and folder paths, you must follow these steps exactly in the sequence presented.
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.
