CA Disk provides comprehensive, efficient, common processing of mixtures of non-VSAM data sets and VSAM clusters. Within a single execution, you can back up, archive, delete and expire partitioned (PO), partitioned extended (POE), physical sequential (PS), physical sequential extended (PSE), direct access (DA), indexed sequential (ISAM), and OS CVOL catalog non-VSAM data sets. You can also back up, archive, delete and expire VSAM clusters, and back up ICF catalogs.
You can do the backups and archives in either an immediate mode, or in a deferred mode in which the back up or archive is actually done at a later time.
You can also direct the output to different media types. For instance, by default backups and archives are written to tape. However, by overriding a couple of sysparms, they can easily be directed to disk. For details, see the step-by-step instructions in Archiving to Disk: Requirements and Recommendations in the Systems Guide.
In addition, the CA Disk restore function allows you restore DA, PO, POE, PS, PSE, and ISAM data sets and OS catalogs without the need for pre-allocation. You can also restore VSAM clusters and ICF catalogs. In most cases, you can even restore to a device type other than that from which the data set was backed up or archived.
It can happen that, due to space problems on dasd, an end-user asks for an explicit Archive of a dataset which has just been restored and the Archive fails with error message :
ADSST011*0387 dsname ON volume BYPASSED , REASON: RECENTLY RESTORED, GRACE PERIOD STILL VALID
