Set up scheduled bi-directional synchronization

This article describes how to set up scheduled bi-directional synchronization of servers or workstations in which data modified on either machine is replicated on interval or schedule to the other machine.


The PeerSync installation should be installed on a machine that can see the folders that need to be synchronized on the two machines—this may be either machine involved in the synchronization or a separate machine.

Step-by-step guide

Perform the following steps on the machine where PeerSync is installed:

  1. Start PeerSync Profiler.
  2. From the Job menu, select Add, and then select Job with Defaults.
  3. From the drop-down list in the top left, change Basic to Advanced.
  4. In the Folder Selection window, enter the local drive path that needs to be replicated in the Source Folder field.
  5. Enter the UNC path or mapped drive letter for the destination of the replicated data in the Target Folder field.
  6. In the Automation window, in the Scanning Options section, schedule the synchronization to Scan Job every x minutes or setting up a daily timer schedule by selecting Scan Job at x.
  7. In the File Options window, select the options Add-synchronize new files and Update-synchronize existing files.
  8. If you would like file and folder deletion events to be replicated to the second server, select the Replicate-Delete unmatched files option .
    If you enable this option, we recommend selecting the Move Options… button, and then selecting a folder or the Recycle Bin to place the deleted files in; otherwise files will be permanently deleted from the system.
  9. In the File Options window, select Bi-directional (both directions), and then click OK in the dialog.
  10. Click the Global Settings link next to the Bi-directional option, and select Use enhanced bi-directional synchronization mode.
  11. In the Options/Commands window, click the button to the right of the Command Line Argument field to open the Current Command Line Argument Selection dialog box. Add /YO- and /QYD:0 to the list of command line arguments. These options are recommended when doing standard or enhanced bi-directional synchronization (i.e., when the Always create a super-set during bi-directional synchronization option is not selected) to ensure that deleted files from one side are not re-added by the other side. These arguments should NOT be used if there are more than two machines involved in a bi-directional synchronization. You can find more information about these options in the PeerSync Help Document.
  12. (Optional) In the Startup/Services window, select the desired startup method.
    To set up PeerSync unattended as a service, choose Install as an NT Service.  If running as a service, make sure the service is using a non-local system account, such as domain admin or any other account that has access to the replicated directories.
  13. From the File menu, select Save or Save As to save the profile.
  14. Run PeerSync by going to Run/View Current Profile.
