After the Crash 1
Transactional replication with queued updates (TRQU) can be a useful way to replicate data if you can tolerate some latency. Sameer Dandage examines the intricacies of backing up and restoring TRQU setups.
Login Security for TRQU

In transactional replication with queued updates (TRQU), the Distributor needs to connect to the Publisher and Subscriber. For security, the replication agents use a special SQL Server login that SQL Server creates during the replication setup for this purpose. This login, distributor_admin, has sysadmin permissions on all SQL Server instances involved in the replication process. You can see this login in the sysxlogins table on all servers.

Looking Under the Hood

Maintaining multiple database servers at multiple sites in active mode and closely synchronizing copies of the data on all servers is a challenge for any DBA. But as long as you can tolerate a little latency, one good option for keeping your data current at all locations is to use SQL Server’s transactional replication with queued updates (TRQU). In the first article in this series, “Queuing Up,” December 2003, InstantDoc 40567, I showed how to set up TRQU.

Queueing Up
If you need to maintain multiple database servers at multiple sites and synchronize all the data, SQL Server has a solution to make your job easier--SQL Server’s Transactional Replication with Queued Updates can help.
Stay in Control 1
Keep your complex software-development projects in check by building a version-control system that uses Enterprise Manager and Visual SourceSafe.
