Reviewing output from an EMC SNAP backup

During an EMC SNAP backup, IMS Recovery Expert writes messages to the job's SYSPRINT DD and other DD statements. Access and review these DD statements to determine if the backup was successful.

SYSPRINT DD

The SYSPRINT DD contains the backup profile information, control cards, and IMS Recovery Expert messages. The following figure shows a sample SYSPRINT DD.

The Snap section of this report lists the target units that now contain the backup of the associated IMS standard volumes. The Data Types section of the report contains the following information:

Data: Yes indicates that the volume contains database data.
DCat: Yes indicates that volume contains a user catalog that contains the z/OS® catalog information for database data sets.
ALog: Yes indicates that the volume contains one or more active log data set(s).
ACat: Yes indicates that the volume contains a user catalog that contains z/OS catalog information for an active log data set.
RLog: Yes indicates that the volume contains one or more archive log data set(s).
RCat: Yes indicates that the volume contains a user catalog that contains z/OS catalog information for an archive log data set.

If a volume contains a mix of database data or catalogs, and log data or catalogs, then IMS Recovery Expert issues a message stating that the database and log data are not separated, and a full system restore is required.

BSYSNAPO DD
