You need to export it in the SCP (under Media).
There you also have additional information on how to download it.
Previosly it was copied to a (S)FTP server, but this no longer has to be the case, since they introduced an object storage (S3) there.
I downloaded it in the format name.raw.zst. However, when I extract it to the name.raw file, its size is very large, making it impossible to upload. How can I use the name.raw format while keeping the file size small?
