Nutanix calls its native snapshot feature Time Stream.
Nutanix calls its cloud backup feature Cloud-Connect.
By combining Nutanix native snapshot feature with its native remote replication mechanism, backup copies can be created on remote Nutanix clusters or within the public cloud (AWS/Azure).
A snapshot is not a backup:
1. For a data copy to be considered a backup, it must at the very least reside on a different physical platform (=controller+disks) to avoid dependencies. If the source fails or gets corrupted, a backup copy should still be accessible for recovery purposes.
2. To avoid further dependencies, a backup copy should reside in a different physical datacenter - away from the source. If the primary datacenter becomes unavailable for whatever reason, a backup copy should still be accessible for recovery purposes.
When considering the above prerequisites, a backup copy can be created by combining snapshot functionality with remote replication functionality to create independent point-in-time data copies on other SDS/HCI clusters or within the public cloud. In ideal situations, the retention policies can be set independently for local and remote point-in-time data copies, so an organization can differentiate between how long the separate backup copies need to be retained.
Apart from the native features, Nutanix ECP can be used in conjunction with external data protection solutions like VMwares free-of-charge vSphere Data Protection (VDP) backup software, as well as any hypervisor compatible 3rd party backup application. VDP is part of the vSphere license and requires the deployment of virtual backup appliances on top of vSphere.
No specific integration exists between Nutanix ECP and VMware VDP.
