Powershell command to extract Frontend Data and Backend Data

[MJL1495]

Hi Team,

We have been exploring Veeam ONE to extract a single report that can contain Frontend Data (total data size of a server/workstation) and Backend Data (Stored in Repository post dedupe/compression). The report is similar to the info visible in Backups -> Disk -> Properties of each backup job.
Somehow, we can find the data (through multiple reports) incase of a VM, but for agent based backups, it is difficult to get such info in a single report. Is there any command/script available (for both VM - VMware, Nutanix/Agent workloads)?

Hi MJL1495,

You will need to poll the following endpoints and use an unsupported method regrettably. I haven't tested on Nutanix workloads, but for Vmware / HV / Agents, the following should work

Get-VBRBackup (CBackup) => use unsupported method GetAllChildrenStorages() to fetch the backup file information itself (VBK / VIB)
Get-VBRRestorePoint (COIb) => AuxData property has the source machine stats as reported by the hypervisor / visible to agent.

Example:

Code: Select all

PS /root> $backups = Get-VBRBackup -Name $vaw.name
PS /root> $backups

Job Name                  Type            Creation Time               VM count
--------                  ----            -------------               --------

PS /root> $rp = Get-VBRRestorePoint -Backup $backups
PS /root> $storages = $backups.GetAllChildrenStorages()
PS /root> $rp.AuxData | Select RealVmSize, DisksCapacity
