Short for Aggregate group Backup And Recovery
Support, ABARS is a backup system for
MVS S/390mainframes from
IBM. ABARS performs data backup and recovery processes
on a predefined set of data called an aggregate. During backup processing, the
data is packaged as a single entity in preparation for taking it off-site. This
enables the recovery of individual applications in user-priority sequence. The
original design of ABARS was for use in disaster recovery,
but is also used for transfer of workloads and remote distribution of
data. [Adapted from IBM DFSMShsm ABARS and Mainstar Solutions (PDF)]
