Running drush sql-sync between linux drupal alias as source and windows drupal alias as target throws rsync:chgrp error
Okay, i got it running. Followed instructions at this blog and i'm able to run it.

Specifically:


  The best way to solve this, is simply to add the following to your
  alias definition file for your local site:


  'target-command-specific' =&gt; array (  //commands used when this alias is the target
'sql-sync' =&gt; array (
  'create-db' =&gt; TRUE,  //create new database(merged databases can be trouble!)
  'mode' =&gt; 'rultvz',  // override sql-sync default $mode = '-akz' from rsync.core.inc
),


),
