rsync timeout when copying folders of mounted volume to local folder

Question

Everytime I start the applescript (with a shell-command), it should transfer not existing folders and files (recursively) into the localfolder (after connecting to a VPN and mounting the volume – both works nice).

mount volume "smb://dfdfdf.ch/e_18_data11$"
delay 4

set sourcefolder to quoted form of POSIX path of ("/Volumes/e_18_data11$/folder1/folder2")
set localfolder to quoted form of POSIX path of ("/Users/dfdfdf/Dropbox/test")

try
    do shell script "/usr/bin/rsync -arvuE --delete " & sourcefolder & " " & localfolder
end try

this gives me a rsync timeout (first error described below):

--> error "rsync: read errors mapping \"/Volumes/e_18_data11$/folder1/folder2/test.pdf\":     Operation timed out (60)

so, basically, it starts syncing, then it disconnects first the volume (like below) and then it disconnects the VPN, too. Why? What should I improve? Thank you.

edit: The source folder size: ~ 1GB

Answer 1

Upgrading to rsync version 3 (instead of OS X Standard Version 2.6) solved the problem.
