# Periodic Replication Options for Nutanix

When you configure a replication group for a Nutanix destination, identify source VMs, and then provide Nutanix-specific values for replication to the destination site.

## Select Replication Type

Select Periodic replication to create new backups and replicate virtual machines to the recovery target hypervisor. The periodic replication method involves taking and cleaning up snapshots frequently on the source VM and requires less bandwidth.

## Production Site and Recovery Site Hypervisor Vendors

- Production site hypervisor vendor: Select the vendor for production site hypervisor.

- Recovery site hypervisor vendor: Select the vendor for recovery site hypervisor.

## General

- Replication group name: Enter a descriptive name for the replication group, or change the name.

- Production site hypervisor: Select the destination hypervisor for the source VMs.

  To create a new hypervisor, click Create new. When you edit an existing replication group, you cannot change this value.

## Content

You must add virtual machines that you want to replicate and failover during disaster.

- Add: Click Add virtual machines, and then select the virtual machines from the VM group that you want to include in the replication group. You can automatically update and sync when VMs are added or removed from the VM group.

## Storage

- Primary copy: Select the primary copy for replication.

  To replicate a VM using a secondary copy, click Add copy. To add a secondary copy, beside Secondary copy, click the Add button , and then select the storage type.

- Copy for replication: Select the storage copy for replication.

## Recovery Options

- Target: Select a previously defined replication target.

  To create a new recovery target, click the Add button .

  When you edit an existing replication group, you cannot change this value.

- Recovery point objective (RPO)

- Replication runs every: Enter how frequently you want to run a replication operation, such as once every 4 Hours or 2 Days.

- Period: Enter the time period for replication frequency.

- Recovery time objective (RTO)

- Hot site replication: Select this option to replicate data to the target after creation of replication group and deploy VMs during failover.

- Enable replication immediately after group creation: To disable replication (recovery) operations after the creation of this replication group, move this toggle key to the left.

## Override Options

### Override replication options

To change the destination settings for a specific VM, in the row for the VM , click the Actions button , and then select Override replication options.

- VM display name: Enter the display name for the destination VM.

You can only change this value when adding a new VM or if the recovery group is a warm site.

- Storage container: Choose a storage container.

- Network settings: Choose a virutual network or subnet.

### Configure Priority

To configure the priority of a specific VM, in the row for the VM, click the Actions , click Change priority, and specify the priority of the VM. 1 is the highest priority.

## Advanced options

- Validate destination VM (Power ON and OFF): Select this option to verify that the destination VM is bootable by powering it on and then powering off. Changes resulting from the power on are not preserved. If guest tools are not installed on the source VM, validation is skipped even when this option is selected.

  If validation fails, the destination virtual machine reverts to its last valid (bootable) state.

- Unconditionally overwrite if VM already exists: To make the first replication operation replace an existing virtual machine with the same name in the target location, even if the destination VM is running, select this option.

  Replication operations for incremental changes are not affected by this setting. Incremental replication changes are applied to the destination VM without overwriting the VM. If the destination VM is currently running, the replication operation fails.

- Continue to next priority on failure: When a VM cannot be included in the replication operation, you can continue to next priority upon failure.

- Failover delay between different priority machines (in mins): Specify how long the replication operation should wait between processing VMs that are assigned different priorities. This setting can be used to enable higher priority machines to start before processing the next set of machines.

## Summary

The summary tab displays the settings that you configured on each tab for this replication group.
