Abstract

An information recovery system (100) includes mountable data volume replications (110) that can be examined for enhanced error detection and correction. An information recovery system provides mounting of partial database replications, such as one or more selected table spaces. With this arrangement, a user can select tablespaces for recovery from a replication of an original database.
