In a multi-domain environment, the Multi-Domain Servers work in active-active mode. All Multi-Domain Servers are active and synchronize each other. Show
The Domains managed by the Multi-Domain
Server The system automatically synchronizes periodically and when an administrator publishes changes to the configuration. How Synchronization WorksDuring synchronization, the system performs these steps without user intervention: On periodic synchronization:
On manual synchronization:
The data that is transferred during synchronization includes:
Initial SynchronizationInitial synchronization occurs automatically when you create a secondary Multi-Domain Server,
Multi-Domain Log Server Multi-Domain Server and
Multi-Domain Log Server Periodic SynchronizationMulti-Domain Servers synchronize with all other peers and Multi-Domain Log Servers. Periodic synchronization occurs automatically, and when an administrator publishes a session. Private (non-published) sessions do not synchronize. Periodic synchronizations are incremental. Only database changes synchronize with peers. Active Domain Management
Servers Manual SynchronizationManual synchronization is a full synchronization that overwrites all data on the peers. It disconnects all connected clients and overrides active sessions and running tasks. When changes made in a session are published on the Active server (made public), the changes are synchronized to the Standby server. Unpublished, private sessions are not synchronized.
For Domain Management Servers, you can only run a manual synchronization from the active Domain Management Server to the standby peers. Manually Synchronizing a Multi-Domain ServerYou can manually synchronize the connected Multi-Domain Server with a peer Multi-Domain Server. To manually synchronize Multi-Domain Servers:
Synchronization starts immediately and the status shows in the window. The synchronization operation can take many minutes to complete.
Manually Synchronizing Domain Management ServersYou can manually synchronization a Standby Domain Management Server with the Active Domain Management Server on a different Multi-Domain Server. To manually synchronize Domain Management Servers for a Domain:
Synchronization starts immediately and the status shows in the window. The synchronization operation can take many minutes to complete. Multi-Domain Server ICA Database SynchronizationWhen you create a new secondary Multi-Domain Server, the Internal Certificate Authority (ICA) on the Primary Multi-Domain Server generates a certificate when you establish SIC How often should WSUS sync?How Often Should I Synchronize a WSUS Server?. Synchronize your WSUS server once every 24 hours at an off-peak time.. If you are automatically approving Definition Updates, synchronize the server at least 2-3 times daily.. If possible, schedule an additional synchronization to coincide with Patch Tuesday.. How do I manually sync WSUS?To manually synchronize the WSUS server
In the WSUS Administration Console, click Options, and then click Synchronization Schedule. Click Synchronize manually, and then click OK.
How long is WSUS synchronization?Note: You can always log into the replica server and manually run the sync after setting the approval status on the primary. Regarding group assignment, changes in the replica can take at least 24 hours to reflect in the primary server.
What is the minimum recommended amount of disk space that should be used for storing WSUS updates?at a minimum, WSUS requires 20 GB to store updates locally; however, we recommend 30 GB based on tested variables.
