() Backup data transfer method is shared memory ( kb).

This Information event is logged to indicate that the Extensible Storage Engine (ESE) backup process is using shared memory to transfer data. During a backup operation, Exchange reads data from the database files using the ESE backup API. Similarly, during a restore operation, Exchange reads data from the backup media using the restore API. To improve performance, the backup and restore APIs use shared memory when the backup application is on the same computer as the ESE instance.
