I use a VBR server in version 11 and I have set up backup jobs that target a scale-out repository (to target a local repository in datacenter + export to S3 bucket).
I've managed to make a report to make sure that the jobs finish successfully, but I'd like to find a way to make sure that the job is also written to the object storage.
You can also get offload sessions using .NET methods as described here.
There won't be any information there on objects processed though.
Please note that the method for getting offload sessions I mentioned and the one for getting restore points in capacity tier as Fabian mentioned above are workarounds. The official solution is still to be implemented.
P.S. There is a difference in getting restore points offloaded in scope of copy and move policies. It is described in the topic Fabian shared, but do let us know if you have any questions.
