A.1 Introduction DB2 for z/OS provides the means to recover data to its current state or to an earlier state (point-in-time). The units of data that can be recovered are table spaces, indexes or index spaces, partitions, and data sets. It also supports the recovery of the entire DB2 subsystem to any point-in-time. To avoid loss of critical data and minimize delays in recovering data, you must develop a comprehensive backup and recovery strategy that includes well-tested procedures to perform the following functions: Create a point-of-consistency for the system when there are no outstanding units-of-work and there are no objects in a restricted state Restore the system to a point-of-consistency Create a point-of-consistency for a set of related data objects Restore the set of data objects to a point-of-consistency Back up the DB2 catalog and directory Recover the DB2 catalog and directory Back up your data Recover your data to current Recover from out-of-space conditions Recover from a hardware or power failure Recover from a z/OS component failure In addition, you must also develop a procedure for off-site recovery in case of a disaster.
