In our previous posts we showed how the Nutanix distributed architecture is well-suited for business critical apps and databases. You can use PD snapshots to restore VMs to the original Nutanix AHV environment. Launch New Nutanix AHV Cluster Wizard, Step 2. When AOS takes the initial snapshot of a VM or volume group, it creates a read-only, zero-space clone of the metadata and makes the underlying VM data immutable. (Get-NTNXCluster -ErrorAction SilentlyContinue)) { Nutanix OS is always optimizing the index or metadata associated with the snapshots in the background for performance and capacity. Snapshots should be able to be used on running applications without causing any performance impacts.

Utilizing application-aware snapshots on Nutanix scale-out architecture shortens quiescence times resulting in more consistent performance. You can use cloning for a variety of purposes, including VM deployment and recovery. Martijn van Willigen You can view the date and time, and the name of the snapshot. The remote cluster option is provided for use cases where storage heavy clusters are used to store Snapshots. All of the virtual machines are running 4K 100% random write tests with IO Meter on a NX-2450. while creating backups and to speed up the restore process (in comparison to restore from image-level backups). Post # Disconnect-NTNXCluster -Server $Cluster Recovery points created manually in the Prism Central console cannot be used to protect and recover Nutanix AHV resources with Veeam Backup for Nutanix AHV.
