VM Replica Provisioned Storage Size

[robby.vecchi]

Hi to Everybody,

Case ID 5208918

I have a Virtual Infrastructure consisting of two hosts that repicaters their respective VMs on the other host local storage.

I have noticed that replicating a powered on VM maker the replica VM Provisioned Storage 2x than the original VM. For example, if
i have a VM with a Hard Disk of 40 GB, its replicated VM has a Provisioned Storage of about 80 GB. That does not happen if the
VM that has to be replicated is powered off.

I think that it has something to do with Snapshots, but i primarly would like to know what's the actual impact on Datastores utilization.

Thank you in advance for any advice about this.

is your source vm thick provisioned?

which version of veeam are you using?

since 6.x there is a chckbox to choose disk type ot replica target. so you are able to create your replicas thin provisioned to save space.

other point depends on amount of recovery point's selected. replica job creates a new "snapshot" for each recovery point. this can cause a lot of space needed.

'Provisioned storage' is simply total base VMDK size * n, where n is the number of snapshots. It's a meaningless metric in vSphere IMHO and has no correlation to the actual amount of disk space in use (which is however indicated by the Used Storage metric).

Thank you jMO, and thank you J1mbo.

I understood my mistake. As a result, storage free space is Total Storage Capacity - Used Space.

So, basically, i can simply ignore the Provisioned Space...all i have to care about, in a configuration like mine, is
the actual free space available. THAT value does not have to reach 0.

Tkank you again for your support and for your replies.
