Kapil:
CIFS is not a separate repository, but rather a "window" into the content stored within either an Alfresco space or web project.
We have two mount path for CIFS, one for collaboration spaces and the other for web projects. Typically, knowledge workers mount Alfresco via CIFS for general DM and collaboration, but do not use the CIFS interface for web content. They typically use the web client and create content using forms rather than using speciality tools like a DreamWeaver.
To mount your ECM spaces, you use the standard Alfresco CIFS mount:
\\servermachine_a\alfresco
To mount your WCM web projects, you use an additional Alfresco CIFS mount:
\\servermachine_a\avm
Because any reads/writes you do via CIFS *is* directly reading and writing assets in Alfresco, you do not need to sync anything. Also, because it literally looks, acts, and feels like a normal mapped network drive, you can readily point any webserver or app server to sit atop it.
Hope that helps.
