Under certain circumstances, the seeding function used by a Replication job may not function correctly. If this occurs, an alternate seeding method is to manually pre-create the replica from a backup and then use the mapping function of the Replication job to map to that restored VM.
Automated seeding is documented in the user guide:
During the initial run after mapping, the job will need to "Calculate disk digest," which will take some time. The disk digest calculation task can be tracked by double-clicking on the job to open the job's statistics and then clicking on the VM to see the digest task.
