Hey, i am seeing this problem with one of my jobs and want to know if there is some way to correct it. Basically i want to restart the machine but cant because this stupid job runs for days stuck at 98%...
why? is it a bug or what?
And why is the backup bottleneck "throttling"? there is no schedule on the job, so why is it throttling?
man i cant seem to be able to attach any images... how do you do that in a forums post? here is the text.

even in the details tab it says that its finished this morning at 10:!5 am but the parent is stuck on merging. i was hoping to be able to run the upgrade to version 10 today. sigh.

This sounds like the throttling applied by Veeam at your service provider’s Cloud Connect instance.
If it is indeed a service provider, ask them to log a case and increase the relevant registry keys for quota allocation during fast clone. We increased these limits by 50x the default to ensure our tenants’ fast clone operations complete within the SLA.
The symptoms you describe seem like you are hitting another limit that is outside of the bandwidth throttling. The merge process doesn’t transfer anything across the wire.
The registry setting that I describe adjusts how Cloud Connect ensures you do not exceed your allowed storage quota at the provider. When you upload a chunk of data, Cloud Connect periodically updates the corresponding database records on the amount of consumed storage. If the updates amount exceeds your allowed quota, the next chunk of data isn’t admitted.
The symptom that you are experiencing is happening because the quota update is a synchronous operation, meaning that the data transfer (or merge) waits for the database to update before it continues. The default quota update is ridiculously small — like 10 MB (maybe 100, don’t remember). Since ReFS merges or synthetic full generation performs at over 3 GB/s, this whole process introduces too much latency. We simply increased the registry setting so that it allocates 16 GB at a time.
The setting has to be implemented by your provider.
