Server-side copy for single remote with different names

Feature
1

According to [this post]{https://forum.rclone.org/t/server-side-copy-sync-between-to-s3-buckets-different-providers/30597/2i} server side copy works only if source and destination are on remotes with the same names. In my setup however I let the user specify different remotes for the backend storage and for the backup, for maximum flexibility, but I'd like rclone to be able to do server side copy if the two different remotes actually have the same endpoint, e.g.:

[backup]
type = s3
endpoint = https:/my.minio.instance/
access_key_id = XXXXX
secret_access_key = YYYYYYY

[storage]
type = s3
endpoint = https:/my.minio.instance/
access_key_id = XXXXX
secret_access_key = YYYYYYY

In this case copying the content of the storage to the backup could be done via server side copy, even if the remote names are different. I'm currently using rclone v1.56.2, is this feature maybe already available in a newer version? If not, is there any chance it will be implemented in future?
Thanks.

welcome to the forum,

  1. rclone selfupdate or download lastest version
  2. copy just one single file using --server-side-across-configs and post the full debug log

I tried with version v1.69.3 and the --server-side-across-configs flags, and it works. I see almost no network traffic during the copy and the debug log shows this:

2025/06/04 08:55:24 DEBUG : urn:oid:10480: md5 = b589f69bedecdbca903f29feba71f813 OK
2025/06/04 08:55:24 INFO  : urn:oid:10480: Copied (server-side copy)

The flag however does not work with version v1.56.2, probably it has been introduced in a later version. I'll update.

Thank you very much for your help!
