Reviewing output from an EMC BCV backup
During an EMC BCV backup, IMS Recovery Expert writes messages to several DD statements. Access and review these DD statements to determine if the backup was successful.

The Split section of this report lists the BCV units that mirrored the standard volumes; these volumes now contain this backup. The Estab (Establish) section of the report lists the next generation BCV units that are now established to the 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 the 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 sets.
- 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 sets.
- 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.
