A quick look: Symantec Backup Exec 12.5 Exchange Agent is a data protection solution that offers continuous backup and recovery.

Backup Exec Agent for Exchange provides continuous data protection for Exchange Server and revolutionizes data protection and recovery by eliminating the daily backup window for Exchange backup jobs while still allowing recovery of individual messages, folders and mailboxes. Patent-pending Granular Recovery Technology allows this to happen in seconds. Additionally, administrators do not need to run a mailbox (or MAPI) backup, which significantly reduces the number of backups, time and cost required to protect Exchange.

With Granular Recovery Technology, the enhanced Exchange Agent can granularly recover from a single full backup, eliminating the need for multiple Exchange backups. Backup Exec 12.5 granular recovery backup jobs can now be easily stored to a remote or removable disk drive, or off to a fiber channel or iSUSI SAN environment. Fast, flexible technology protects vital Exchange Server 2000, 2003, and 2007 data while the application is still online. Note: This product does not include Symantec's support plan.
