Starting mirroring in Management Console without synchronizing
When you start mirroring on a subscription, all tables with a replication method of Mirror and a status of Refresh are initially refreshed on the subscription. This synchronizes your source and target tables. If you want to start mirroring without a refresh, you can do this by setting manually a capture point from which the mirroring will start. This may be useful, for example, when you know that your frontend and backend databases are synchronized already. If your subscription contains a lot of data, starting mirroring without a refresh can save time.
Procedure
1 Ensure you have ended any active replication on the subscription that contains the source table.
2 Mark the table capture point using Management Console or the dmmarktablecapturepoint command.
