[Dovecot] dsync doubts

[Piotr NetExpert]

Hi everyone,

I want to backup mailboxes to another server. A usage information for 
dsync says "... <remote dsync command>". Does it mean I need dsync 
installed on the other server too?

Now when I try to run dsync I receive:
# dsync -v -D -u abc backup ssh user at other.server
dsync(username): Debug: Effective uid=123, gid=123, home=/path/abc
dsync(username): Debug: maildir++: root=/path/abc, index=, control=, 
inbox=/path/abc
dsync-local(abc): Debug: Namespace : Using permissions from /path/abc: 
mode=0700 gid=-1
Password:
server: not found
dsync-local(abc): Error: read() from worker server failed: EOF

What could be wrong? How can I check what it wants to do and cannot? I 
cannot find more information I need in a wiki page of dsync.
