How EMBR Works with Instant Access

Block backups of an Exchange server back up the logical volume (C:, D:, etc.) that contains the Exchange database files, which includes the EDB files. By virtue of the Block backup process, the database is backed up online once as a base backup; all subsequent backups are then block-level incremental backups, which greatly reduce CPU load, network traffic, and storage requirements.

Any of the snapshots (one is created by each Block backup job) can then be mounted to a Windows node by using the IA feature. If EMBR is installed on this Windows node (the node should not be the Exchange Server), EMBR can then be used to extract mailbox items from the IA map.
