RE: [ActiveDir] FRS Replication

[Almeida Pinto, Jorge de]

take a look at "How FRS Works" : http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/TechRef/7636aede-a944-4765-8973-40dc1e1f2d56.mspx

 

From the "Windows Server 2003 Active Directory Branch Office Guide_v11"  chapter "03_Plan_Physical.doc"

 

SYSVOL Schedules

The SYSVOL schedule is an attribute associated with each NTFRS Replica Set object and with each NTDS Connection object. FRS replicates SYSVOL using the same intrasite connection objects and schedule built by the KCC for Active Directory replication. FRS replication behavior is different, depending on whether the connection is for intrasite replication or intersite replication of SYSVOL:

·         SYSVOL connection within a site. The connection is always considered to be on; any schedule is ignored, and changed files are replicated immediately.

·         SYSVOL connection between sites. SYSVOL replication is initiated between two intersite members at the start of the first 15-minute quarter when the intersite schedule opens. The connection is treated as a trigger schedule. The source partner ignores its schedule and responds to any request by the destination partner. When the schedule closes, the source partner unjoins the connection only after the current contents of the outbound log, at the time of join, have been sent and acknowledged.

Because SYSVOL replication uses the same schedule, modifying the Active Directory replication schedule also affects SYSVOL.

Hi,

 

I'm wondering how FRS replicates it's data to outbound partners located in other Sites. I know the intrasite replication work a bit like AD replication but...

 

Does FRS bother to check for intersite connection objects and replication interval to send out file updates?

Is it only using the schedule for the replica set?

 

I'm pretty sure I've read that it will bother with site link costs to figure out the cheapest way to replicate but the questions above remain.

 

Any help greatly appreciated.

 

Thanks,

Francis
