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:
On the Restore Mode tab, select "Restore to a new location or with different settings".
On the same tab, click Pick Proxy to Use and select the proxy on the destination side.
On the Hosttab, select the target host you want the replica to reside on.
On the Resource Pool tab, select whichever resource pool, if any, you want the replica to use.
On the Datastoretab, select each VM disk and set the Disk Type to "Thin".
On the Folder tab, change the VM name by highlighting the VM and clicking “Name…” at the bottom. It is suggested to add the suffix “_replica”.
On the Network tab, specify how the new location’s network.
On the Summarytab, do NOT check "Power on VM after restoring"
Click Finish to start the restore.
Part 2: Mapping to the restored VM
When the restore completes, create/edit the replication job.
On the Name tab, mark the Replica seeding (for low bandwidth DR sites) option.
On the Destinationtab, make sure the settings match the present location of the restored VM that will become the replica.
On the Seedingtab, check Map replicas to existing VMs, and configure the mapping:
Highlight the production VM
Map it to the VM you restored on the TARGET site in Part 1 of this KB.
Once you have mapped the restored VM (now replica) to the original VM, next through until you have completed the rest of the job settings.
Finish configuring the job, and run it.
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.
