Several data sets were deleted due to wrongly set expiration date modified.
We would like to restore them and for this we would like to know how can we get the backup information from a copy of the files data set or in our case the CA-Datacom database.

How to Recover a Datacom Files from a Backup
A backup of the Datacom Files restored into a new DBID can be used to research previously deleted DSNINDEX and ARCHVOL records for recovery. If the ARCHVOLs still exist, the missing data sets can be restored using the backup. If restore is not required, the ARCHVOLs can be used with REBUILD to bring back the missing DSNINDEX records into the production Files.
This process is only recommended if a broad range of data sets have been lost. Single data sets or ARCHVOLS should continue to use the Rebuild functionality or the Datacom recovery processing and rebuild the entries using Datacom logs.
Notice that you can have lost data sets which you will never recover. All depends on the situation, it is an eventuality to consider.
In any case, please contact our Support team for assistance and so they are aware of the situation.
