Uploading files to S3 bucket for migration without high RAM consumption

Hello All, I am trying to upload files around 500G to few TBs on S3 bucket for migration from on-prem. I tried multi-part upload but its eating up RAM on On-Prem server. Any suggestions, workarounds :thinking_face:

there are a few suggestions…Snowcone might be the recommended method.

Thanks, unfortunately there was long delay in snowcone delivery. We removed few blockers from firewall, and copied over with better bandwidth.
