The JCL backs up the IVP data sets then restores selected data sets. Consider the test backup and batch restore function an automated archival. The operation scans all the data sets on a volume or group of volumes. Then, based on the criteria you supply, the operation archives certain data sets and retains others on the volume. Because test backup and batch restore is a powerful function, a SIMULATE mode is provided. We recommend that you run only simulations until you achieve the results you want.
Specification of the retention criteria is flexible and complex. See the information in the Basic System—DMS PROC and Backup/Archive sections and the PARMLIB section of the Systems Guide when you set up your own DSCL selection criteria.
The evaluation JCL allows backup of an empty file. The ARCEMPTYY parameter is specified under //SYSPARMS DD to allow backup operations to archive empty data sets.
After backup, several data sets are in the archives. To restore the archived data sets, use the RESTORE function.
If you want the data set restored to a volume other than the one it was archived from, include the VOL= parameter to direct CA Disk to a particular volume. Default disposition for a restore operation is to catalog the data set following the restore. Because the original data set still exists on DASD, use the PREALLOCY parameter to allow Restore operations to overwrite pre-existing non-VSAM data sets.
