Hello,

Some code that I didn’t write but am maintaining passes a local script’s path as dsync’s “destination” argument, like so:

dsync -D -u john -v backup -R -1 "/code/dsync_client.pl" 127.0.0.1 john@mydomain.org

dsync_client.pl establishes a TCP connection with a remote dsync process then acts as a proxy between the two dsync processes. “127.0.0.1” and “john@mydomain.org” are given as arguments to dsync_client.pl.

I don’t see this usage described in dsync’s man page. I just want to be sure: is this a supported use of dsync?

Thank you!

Is there any reason why you are doing it this way and not using it the way it is usually used? backup does not support -1 btw.

doveadm backup -u john -R ssh sshuser@remote "sudo /usr/bin/doveadm dsync-server -u john"

Isn’t this actually the same syntax that I’m asking about, where <destination> is a command name and arguments? I guess the documentation is just in want of emendation to mention this usage?
