$Session = Get-VBRRestorePoint | where{$_.Name -eq <VmName>} | Where{$_.Type -eq "Snapshot"} | Sort CreationTime -Descending | Select -First 12
I've succeeded in gathering some information like ( by "$Session.AuxData.ReplSummary" ) :
JobName | CreationDate | OrigVmName | OrigVmRef | OrigEsxName | OrigDisplayPath
To get the Snapshot Size ( the Restore Point ), I've used $Session.ApproxSize .
What I would like, it is to get the VM_replica Size on the Datastore ( It's real size must be the Used Storage ). With the command Get-VBRServer -Name $ESX | Find-VBRviDatastore, we can retrieve the Capacity and the FreeSpace.

Is there a Powershell Command to get all VM's Replica size on Datastore ? Or Do I Have to Install a PowerCLI

Many Thanks
