FRS overview
FRS is a Windows server tool designed to enable fast recovery when an
Exchange storage group maintained on an HP disk array becomes
damaged.
The FRS life cycle can be summarized as follows:
• (1) The production server maintains production storage groups or
databases on specified production volumes of the disk array.
• (2) The FRS GUI runs on the recovery server. It captures copies of the
Exchange storage groups from the production volumes and stores
them on recovery volumes of the array. FRS creates, maintains, and
manages these “recovery-ready” copies.
• (3) When a data corruption occurs, the administrator uses the FRS
graphical user interface to replace the damaged storage group or
database with the most recent known good recovery-ready copy.
