Explanation

Transaction redundancy refers to off-site methods of protecting transaction data. Electronic Vaulting transmits batches of data to a remote site, Remote Journaling transmits transaction logs in near real-time to an off-site location, and Database Shadowing maintains a live duplicate database at a remote site. On-site mirroring duplicates data locally (same site), so it is NOT a transaction redundancy implementation - it provides local redundancy but does not protect against a site-wide disaster.
