Server-side copy (sync) between to S3 buckets (different providers)

What is the problem you are having with rclone ?

I'm trying to sync two S3 buckets on different providers (OVH and Scaleway) but server-side copy doesn't seem to work.

Does it work only on buckets within the same provider (OVH > OVH) ?

Run the command 'rclone version' and share the full output of the command.

rclone v1.58.1

  • os/version: ubuntu 20.04 (64 bit)
  • os/kernel: 5.4.0-109-generic (x86_64)
  • os/type: linux
  • os/arch: amd64
  • go/version: go1.17.9
  • go/linking: static
  • go/tags: none

Which cloud storage system are you using? (eg Google Drive)


The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone sync ovh:data scw:data --s3-storage-class GLACIER --fast-list --checksum

The rclone config contents with secrets removed.

type = s3
provider = Scaleway
access_key_id =
secret_access_key =
region = fr-par
endpoint =
acl = private

type = s3
provider = Other
access_key_id =
secret_access_key =
region = de
endpoint =
acl = private

A log from the command with the -vv flag

I found this:

Server-side copies will only be attempted if the remote names are the same.

This answer my question but it is not very clear on docs. Let me improve that.

Not really just if the remote names are the same.

You can only server side copy generally if you are on the same provider.

Google Drive to Google Drive between remotes is fine as an example.

In your case, you are trying to server side from one provider to another which isn't a thing while they are both S3, they are different providers.
