Short for
Aggregate group Backup And Recovery
Support, ABARS is a
backup system for
MVS S/390 mainframes 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.
