This invention is a system and method for managing replication of data distributed over one or more computer systems. The method includes the computer-executed steps of establishing one or more mirrored copies of data that are copies of one or more volumes of standard data (e.g. a database) on a first computer system. The mirrored copies of data are separated or split from the standard data. A map is created relating logical information to physical devices on the first computer system. Then a duplicate of the one or more mirrored copies of data is mounted on the second computer system by using the map to create another volume group on the second computer. It is substantially identical to the first volume group. The first and second computer may be integrally combined.

System and method for managing replication sets of data distributed over one or more computer systems

A method and system for assisting with backup and restore operations of data stored in a data storage system is provided. The server and client processes of the backup and restore application include software which allow both processes to communicate with one another either over a network or through the data storage system. The server and client processes are capable of recognizing the calls for both types of communication mechanisms needed for either network or data storage system communications. Once the type of call is recognized the processes can direct the call to the appropriate communication mechanism.

Method and system for assisting in backups and restore operation over different channels

An information recovery system includes mountable data volume replications that can be examined for enhanced error detection and correction.

Information replication system having enhanced error detection and recovery

An information recovery system mounts partial database replications, such as selected tablespaces, on a target host.
