Does CV use multipart uploads to AWS Glacier - direct?

Hi all!


We are troubleshooting some AWS Glacier upload performance issues and one of the questions the AWS engineer came back with is:


Do you know if they use multipart upload in their solution? That is usually the first thing to check -


I did find some suggestions that we do use it:


  • Here it states that we need MultiPart permissions:
  • In previous service packs, there was an Additional Setting (nCloudMultipartSizeKB) to tune the the multipart size.


But I would like to get some hard evidence.


  1. Does Commvault use multipart uploads to AWG Glacier - direct?
  2. Can we prove that with certain log file entries?


Thanks in advance!

Yes, it uses multipart upload for Glacier service. You can set CloudActivity-cvd.log(or CloudActivity.log after SP23) to debug level 2 on MediaAgent. it will log the full URL for cloud requests.
