Step 3. Select Source and Target Repositories

At the Storage Mapping step of the wizard, select a source repository from which you want to copy backups and a target repository where you want to store the copies.

1. Click Add to open the Add Repository window.
2. From the Source backup repository list, select a backup repository from which you want to copy backup files. The unsupported backup repositories are not shown in the list.
3. From the Target backup repository list, select a backup repository where you want to store the copies. The unsupported backup repositories are not shown in the list.

Requirements and Limitations for Source and Target Repositories

When you create storage copy jobs, check the following prerequisites and limitations for the source and target repositories:

• The source and target backup repositories must be HPE StoreOnce or Dell Data Domain backup repositories, or scale-out backup repositories that consist of only HPE StoreOnce or only Dell Data Domain repositories.
• [For scale-out backup repositories] The file placement policy must be Data locality. For more information, see Data locality.
• Within one storage copy job, you can use each repository as a source only once.
• You must not create the same pairs of source and target repositories, even in different storage copy jobs.

Requirements for Data Flow

When you create storage copy jobs, check that you do not create loops in data flow across all storage copy jobs. This means that data copied from one repository must not be copied to it again. The following image shows storage copy jobs configured correctly (without loops) and incorrectly (with loops).
