Thanks a lot for your post. It is very helpful.
So It is very interessting, that you have looked for your value about Data on network and Data Written.
As you say, I think that it's normal that all data transmitted on the network were written, as the aux copy work with source dedup !
The strange fact is the beginning of the charts !
I haven't find yet the change that I have made on the end of november !
Currently, I have just made a report of all aux copie, redirected to csv output. Then I have created the chart with excel !
It seems that the problem occur on all the DDB, and aux copy. It's more difficult to identify the problem on the other AuxCopy because there less data to be copied.
Currently, we have a call with the CommVault Support.
We have run IOMeter tests on our DDB Storage, and it seems that the storage is'nt suitable . We get 400 IOPS, and we need to get 800 IOPS belong the CommVault Documentation !
So we need to improve our storage performance.
I think that before the first backup, I have already run the same test, and I had no problem with IOPS !
But the strange things are :
- It seems that the perform decrease quickly, so I think it should be a wrong parameter !
- The first test I have run with IO meter was better than now ....
So I need to investigate about that.
I'll take inform about news !
Thanks again for your posts , it was very helpfull !
