Backup Set Adoption

Previous backup sets from other machines may be adopted in place instead of re-uploading all backup data. This applies for all crashplan installs.

• Start container.

• Sign in to your account.

• Click the Replace Existing button to start the wizard.

• SKIP File Transfer.

• Once done with the wizard, go to your device’s details and click Manage Files. You will probably see missing items in the file selection. This is normal, since path to your files may be different in the container.

• Update the file selection by re-adding your files. Do not unselect missing items yet.

• Perform a backup. Because of deduplication, files will not be uploaded again.

• Once the backup is terminated, you can remove missing items if you don’t care about file versions. Else, keep missing items.
