Hello,

To improve out RTO time we are thinking about following scenario:

current we backup VM via VSA backup to MA, and AuxCopy then the data to a CIFS share which is sitting on a NetApp with SnapLock configured . In case of ransomware attack, we will restoration via VM restoration process from the CIFS share.

In future we want restore in case of disaster direct the volume which host the VMs

now my question is possible to handle this during commvault completely?  VM backup configured with IntelliSnap take snapshot on volume, then it triggers a SnapVault to a NearStore only for full backups (SnapLock configured), after this it takes backup copy for standard backup, where we have longer retention and possibility to restore single VM or single files….

In case of disaster, we can restore full backup volume via IntelliSnap restoration then we restore VM backups from the standard backup. This should be much faster as restore whole VM from VSA backups.

Question is will this work, or is there a thinking error.

we use :

v11sp28.36,

VM: indexversion 1

Hey @Juergen,

There is a lot here but I want to start with the objective of getting faster RTO.

IntelliSnap on VMware does not necessarily give you this. Backups are taken at the volume level, and for accelerated recovery you’d want to do a revert on the volume - however this would erase/recover all VMs on the same volume and hence this option is not allowed in the software - UNLESS your VM is running on an NFS datastore/volume on a NetApp array. This is the only configuration that allows for individual VM revert (outside of vSan). Outside of this, the recovery of a full VM from intellisnap relates to mounting the snapshot and copying the data from the old to the new destination. That may not be any quicker than restoring from backup storage.

For faster RTO you could leverage a VM replica (VM replication) or try live recovery from snap (which requires R/W to the snapshot so not sure that would work in your scenario).

Hello @Damian Andre 

thanks for your answer.

Outside of this, the recovery of a full VM from intellisnap relates to mounting the snapshot and copying the data from the old to the new destination. The question is - what is copying the data here? Are we doing this on the array, independent of CV?

thanks
