Where does compress happen?

If my destination folder is a network share does SQL BKP 4.6 compress onto the local server 1st before it is sent across to the remote share?

I have a 65Gig DB that is backed up to a remote site via a 25MB radio link, compression speed is about 2.88MB/s.

Doing the the backup locally I get a compression speed of about 39.3MB/s.

    SQL Backup never compresses to a local folder before transferring to the entered destination, even if the entered destination is a remote share.

    Is your link speed 25 megabytes/sec, or 25 megabits/sec? If the latter, then the throughput of 2.88 MB/sec is about right.

    If you were to perform a native backup to the remote share via that link, what is the throughput achieved?
