Live Sync Virtual Machine Replication

Live Sync can be used to create and maintain warm recovery sites for virtual machines running critical business applications.

The Live Sync feature enables incremental replication from a backup of a virtual machine (source VM) to a synced copy of the virtual machine (destination VM). The Live Sync operation opens the destination VM and applies changes from the source VM backups since the last sync point.

The Live Sync feature can initiate replication automatically after backups or on a scheduled basis (for example, daily or once a week), without requiring any additional action from users. Using backup data for replications minimizes the impact on the production workload by avoiding the need to read the source VM again for replication. In addition, in cases where corruption on the source VM is replicated to the destination VM, users can still recover a point-in-time version of the source VM from older backups.

The following table shows the Virtual Server Agent hypervisors that support live sync and the live sync features that each hypervisor supports:

 Note:

  • You can manage live sync schedules created in CommCell Console or Admin Console from Admin Console replication groups.
  • For conversion to Azure or Azure Stack: The operating system for the destination VM must be an operating system that is supported for Microsoft Azure.
  • Before you convert a VM from a non-Azure hypervisor using a "restore as" operation or a Live Sync operation, verify that the source VM meets the requirements for non-endorsed distributions. This verification is important because Linux VMs that are based on an endorsed distribution of Microsoft Azure have the prerequisites that enable them to run on Azure, but VMs that originate from other hypervisors might not. When For more information, see Information for Non-Endorsed Distributions.
