Cloning Migration Media

To ensure that you can recover all your data, you should regularly clone your migration media. Because Backup only backs up the stub file on the client computer, not the migrated data itself, the clone might contain the only extra copy of a file. You can specify cloning to occur automatically after the migration process is completed by selecting the Migration Clone pool in the group resource you created for your migration clients. Clones of migration data must be written to volumes from a pool of type "migration clone." See "Using the Migration and Migration Clone Pools" for more information.
