Oracle Data Guard (Oracle specific
term)
Oracle Data Guard is Oracle’s primary
disaster recovery solution. Oracle Data
Guard is able to maintain up to nine
standby databases, each of which is a
real-time copy of the production
(primary) database, to protect against
corruptions, data failures, human errors,
and disasters. If a failure occurs on the
production (primary) database, then a
failover to one of the standby databases
which becomes the new primary

planned downtime for maintenance can
be reduced because the production
processing can be moved from the
current primary database to a standby
database and back quickly.
