…server side copy hasn’t been implemented for Yandex.
Seems I was lost in translation and misunderstood features table
Anyway I’ll follow your advice and open issue on github. To keep this topic consistent here is the link to Yandex.Disk API page.
Maybe you’d like to implement it?
I’d be happy to take part in rclone development, but my coding experience ended in the mid-nineties. I think thorough testing would be my best contribution to the project.
P.S. Yandex began public testing of its cloud service, and Object Storage supports HTTP API Amazon S3 (translated Yandex.Cloud page ).
