Abstract

For performing incremental replication of a data set, a source data module identifies a source data set, the source data set including a set of storage locations on a source volume, a target data module that defines the target data set in response to the source data module identifying the source data set, a mapping module that stores a replication relationship table, the replication relationship table mapping the defined data set to a target data set, the target data set including a set of storage locations on a target volume, and a replication module that performs an incremental copy of data stored at the source data set based on the replication relationship.

Claims20

Dependent claims

An apparatus comprising:

a source data module that identifies a source data set from a partially qualified data set name, the source data set including a set of storage locations on a source volume;
a target data module that defines the target data set in response to the source data module identifying the source data set;
a mapping module that stores a replication relationship table, the replication relationship table mapping the source data set to a target data set, the target data set including a set of storage locations on a target volume;
and
a replication module that periodically performs an incremental copy of data stored at the source data set based on the replication relationship table,
wherein at least a portion of the source data module, the target data module, the mapping module, and the replication module comprise one or more of hardware and executable code, the executable code stored on one or more computer readable storage media.
