Multipart upload with respect to nonworm policy and WORM enabled policy

Question

When I use WORM-enabled storage policy to backup a file. I can see from the Object store logs that the PUT requests include partNumber and uploadID. See the example below.

PUT /2.6wormtest/Z5YO4V_09.06.2024_10.43/CV_MAGNETIC/V_342/CHUNK_1294/SFILE_CONTAINER_020?partNumber=1&uploadId=7ffffe6e38ff88e4 HTTP/1.1

When using a NONWORM policy to backup the same file, the received PUT request does not include the partNumber or uploadID. See the example below.

PUT /windowsnonworm/1DWYIV_09.11.2024_10.49/CV_MAGNETIC/V_8220/CHUNK_84999/SFILE_CONTAINER_001.FOLDER/0 HTTP/1.1" 200

My question is, does Commvault not employ multipart upload during a backup with the standard (WORM disabled) policy?

Hi @Dipayan Sarkar ,

Commvault uses multipart upload for the AWS-S3 storages on which micro pruning is disabled like WORM enabled or Archive tier storages.

Hope this helps.
