System Programmer Reference › Managing CA VM:Backup Catalogs › Catalog File Structure › Data Files

Data Files

These files use the filetypes DUMPJOB, DETAIL, and FILEnnnn. They store the following information:

• What data was backed up
• When it was backed up
• How it was processed
• Where it is located on tape

An 8-digit filename is given to both DUMPJOB and DETAIL files. These numbers are assigned sequentially by CA VM:Backup whenever a backup job creates a catalog. The filename that is given to FILEnnnn files indicates the volser of a tape that is used in the backup.
