OneWaySync



I have 2 SQL Server Databases A and B, and I want to synchronize (continuously, every 10 minutes, max) the data from 70-80% percent of the tables from A to B (just A - B, B is a read only database. OneDrive - Is one way sync an option We have Mac and Windows users that are licensed for OneDrive for Business and we would like to use the 1TB storage per users we have. But how can you use the OneDrive client to take advantage of 1TB if it is syncing locally to the client computer. Our client computers have barely 200GB of space available. We have our AD in Azure AD, and for few reasons I need to synchronize the Azure AD with one server on-premise. I want to sync from Azure AD to this server and it must be a one way sync. From what I've seen, Azure AD Connect only offers two ways sync when syncing from Azure AD to a server. Do you have any recommendations for this specific case?

Overview

Some deployments would prefer that AD sync is only performed in one direction. Certain deployments would like updates to originate from the AD side while other deployments would like updates to originate from the DS side.

Configuration

To implement one-way sync, we need to add a new configuration attribute to the sync agreement entry. This attribute will be named oneWaySync. If this attribute is not present, the sync agreement will be bi-directional. To configure a uni-directional agreement, this attribute can be set to toWindows or fromWindows as desired.

Implementation Details

From Windows Case (AD -> DS)

We don’t want to change the RUV implementation for a one way sync agreement, so we will just fast-forward the RUV that we maintain for the AD system as if we had successfully sent the changes.

To Windows Case (DS -> AD)

Inside of the replication plug-in, we skip sending the Dirsync control to AD in both the total and incremental replication protocol sessions when oneWaySync is set to toWindows.

Consistency Issues

From Windows Case (AD -> DS)

If one way sync is enabled and changes are made to a synced entry on the AD side, a replication session with AD will be started. In this session, we will not send any updates, but we will send the Dirsync control to AD to pull any updates. This will result in an inconsistency in the modified entry between AD and DS. This inconsistency will be resolved the next time any update is made to the entry on the AD side since we compare the entire entry between AD and DS when we receive a change via Dirsync. To avoid these inconsistencies, it is recommended to not allow direct updates to synced attributes in entries on the DS side. One can configure access control to help enforce this.

Another inconsistency that can occur is if a synced entry is directly deleted from DS. This deletion is not sent to AD. In this case, an update to the entry on the AD side will result in the entry being added back to DS. The direct deletion of synced entries on the DS side should be avoided to prevent these inconsistencies.
