Replication Process

Updated

A replication operation performs full replication after a full backup, or writes incremental changes after an incremental backup. If no new backups have been run since the last replication, a scheduled replication operation runs but does not replicate any data.

Full Replication

The replication operation does not verify the boot status of the replicated VM.

Because of an Azure API limitation, a VM cannot be deployed without a network.

  1. Use the VM configuration to restore the VM in the specified resource group and storage account.

  2. Create an integrity snapshot for the VM.

  3. Deploy the VM using blob storage.

Incremental Replication

  1. Verify that the destination VM exists on Azure.

  2. Verify the integrity snapshot on blob storage.

  3. Delete the VM.

  4. Revert blobs to the integrity snapshot state.

  5. On the blob storage, apply incremental changes from the source VM backups since the last sync point.

  6. Create a new integrity snapshot.

  7. Deploy the VM.
