multi-path is heavily need and has it support

But there still a little problem: is the project support multipath?
For example, I want to scp a(local) to b(remote), and c(local) to d(remote).

Now I wrote the following format, but it didn’t work.

Then what is the corrent format, or did it support the function?

Thanks a million and look forward for your replying.

Why don't you just run two instances of sync simultaneously?
