AWS S3 bucket to bucket copy

[oceanthrsty (Matt)]

I apologize if this is a newb question.

If I'm doing a rclone copy and the source is an AWS S3 bucket and the destination is a different AWS S3 bucket on the same account. So the copy command would look like:

rclone copy gfevents:gfevents/Workspace/ gfevents:gfcastesting/Workspace

And I'm running this from my local computer.
Will the data flow from the source bucket directly to the destination bucket
OR
From the source down to my computer and then up to the destination?

Thanks.

hello,

for that command, the copy would be server-side.
this can be seen with a debug log.
notice 0 Byte/s, no local bandwidth was used.

i ran this command two times and in both cases, the transfer took the same time.

• on a cellphone over wifi.
• on a desktop with a 1Gbps internet connection
