FILEnnnn Files

Each FILEnnnn file contains pointers to the following:

• FILEnnnn files for any tape copies created during the job
• DUMPJOB file created for the backup
• Next tape used in the same job
• Corresponding DETAIL file

Each file also maintains information about the tape expiration date, the data set name on the tape, and the name of the resource pool to which the tape is defined.

CA VM:Backup creates one FILEnnnn file for each tape used in a backup, where nnnn is the data set sequence number assigned to the tape. This number is always 0001 because CA VM:Backup does not support appending new backup datasets to existing volumes.
