Syncing folders over network -- syntax

[Georgi Kourtev]

Hello,

I am trying to sync one folder of my PC with a network folder under samba.  Is 
this the correct syntax:

rsync -r -t -v --progress -s /home/Documents/Folder smb://PC-
desktop/share/Documents

I have error when using the above. The output of rsync is 

ssh: Could not resolve hostname smb: Name or service not known
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(601) [sender=3.0.7]
Rsync process exit status: 255

Thanks.
