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 -https://docs.aws.amazon.com/amazonglacier/latest/dev/uploading-archive-mpu.html
I did find some suggestions that we do use it:
- Here it states that we need MultiPart permissions: https://documentation.commvault.com/commvault/v11_sp20/article?p=91277.htm
- 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.
- Does Commvault use multipart uploads to AWG Glacier - direct?
- Can we prove that with certain log file entries?
Thanks in advance!

@Ho-chi Chen !
I marked his reply as the Best Answer though feel free to reply back letting me know that is premature.
Thanks for confirming! I’ll look into the log setting!
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.
