Log Shipping vs database mirroring. Today was the first notice I received that anyone had replied to this thread. This generally means that you are doing the log backups more frequently than you would be otherwise. This puts a considerably higher load on your disk subsystem, and if your disks are not setup optimally, you can experience system wide slowdown because of waits caused by log operations. That means less worker threads for processing queries. This is true whether you are mirroring synchonously (high safety) or asynchonously (high performance). If the mirrored database is experiencing high transactions, your databases will not be in sync, and if there is an outage, it could result in significant data loss. If transactions are being queued, the part of the tran log that has not been committed on the mirror can not be truncated or over- written. This can result in larger tran logs. If the tran logs get too big, and the servers are rebooted, database mirroring may not be able to resume mirroring because the scan of the transaction log will time out before the mirroring connection can be re- established. When this happens, SQL Server will keep both sides of the database offline leaving neither principal nor mirror available. The only way to recover from this scenario is to drop mirroring, shrink the log file, and then set up mirroring starting with a new full backup. If the databases are in different domains or geographical locations, you should use log shipping. Database mirroring will have difficulty maintaining the connection well enough to be effective.
