msdeploy using provider dbsqlFull to sync sql server database

I am trying to use msdeploy to sync two database from different machines.
The command I am using: msdeploy.exe -verb:sync -source:dbFullSql="Data
Source=AMachine;Initial Catalog=RegGate;User ID=sa;Password=aaa@123"
-dest:dbFullSql="Data Source=BMachine;Initial Catalog=WebDeployTest;User
ID=sa;Password=bbb@123" -verbose
The first time it runs successfully and the two database gets synced. When
I try to run the same command second time, after making some changes to
first database, I get the following error.
Verbose: Performing synchronization pass #1. Verbose: No backup was
executed. Info: Adding database (MSDeploy.dbFullSql/dbFullSql[@path='data
source=BMachine;initial catalog=WebDeployTest;user id=sa']/sqlScript)
