Veeam Reported Replica Sizes vs Azure Blob Usage

[TerribleEric]

When I use Get-VBRRestorePoint to export and sum up the BackupSize data, I am getting a number that's 2-3x greater than the storage I'm seeing used in Azure. We do immediate copy for the Capacity tier, and I do realized that copied points show up as Internal, but that doesn't seem to make a difference in the totals. I don't see any duplicates in my export and I can correlate the restore points to those I see in Backups>Capacity Tier>Job Name. Is there a ton of compression done when Veeam chunks up the VBKs and VIBs in the performance tier and shuttles the blocks off to Azure blob storage? Is there anywhere in Veeam I can get better information on the restore point level storage usage in Azure?

BTW, the reason I'm trying to get the restore point sizes it to try to get as accurate a calculation as possible for storage costs/savings if we switch from just Hot tier to a Cool\Archive combo, as some of our VMs we have to keep for several years, while others we really only need to keep for a month. Taking the entire blob of data and saying the cost change will be X based on the difference between hot and cool won't be good enough, as I need to take into account the VMs with longer retention that would get moved to Archive after 30 days. I could do it proportionally to what Veeam is reporting, but if that's not accurate to begin with...

Hi @TerribleEric,

I think this might just be a bit of a not so clear element with what is reported on, as by default what is stored will be the total data size offloaded before the space savings on Capacity Tier; when you mention the copied points show up as Internal, how are you checking that or rather where do you see it? (Which property on what kind of Powershell object?) Basically, I think that factor is throwing off your calculations; I would still advise plan for the sizes returned by the UI since the space savings are heavily dependent on the workload.

The current cmdlets don't have a great way of returning the actual sizes directly, but you can use the above script to report on backups in Capacity Tier, but you can also check in the Properties of the Backup under the Home Tab > Backups > Capacity Tier > Right-Click > Properties.

We also have a VeeamOne report https://helpcenter.veeam.com/docs/one/r ... er&ver=120 which might help you here as you can export this out and do your capacity planning that way.

Reporting via Powershell is doable but we need to go into unsupported methods right now to get the accuracy I think you're looking for, so would the above two options help for your planning purposes?
