A validated backup solution should be chosen for the VMware Virtual Machines, such as Microsoft Azure Backup Server (MABS) or from our backup partners .

Note:

Private cloud vCenter and NSX-T configurations are on an hourly backup schedule. Backups are kept for three days.

  • VMware vSAN storage policies on Azure VMware Solution are implemented with storage availability in mind. When the cluster has between 3 and 5 hosts, the number of host failures to tolerate without loss of data equals 1; when the cluster has between 6 and 16 hosts, the number of host failures to tolerate before data loss can occur equals 2. VMware vSAN storage policies can be applied on a per-VM basis. Whilst these are the default policies, there is the ability to amend the policy used for VMware VMs to suit custom requirements.

  • VMware High Availability (HA) is enabled by default on AVS. The HA admittance policy ensures a reservation of the compute and memory capacity of a single node ensuring sufficient reserve capacity to restart workloads in another node in an AVS cluster.

  • Currently Microsoft Azure Backup Server (MABS) does not support restoring backups to an alternative (secondary) AVS private cloud. Refer to the disaster recovery section of this guidance when cross AVS recovery is required.
