In the case of logical data backup with HSMS (see the "HSMS" manual [14 (Related publications)]), BS2000 files, POSIX files, and job variables of the local BS2000 system are read from one or more data media and saved consecutively to a backup file on one or more data media.
Only BS2000 files and job variables can be saved with ARCHIVE (see the "ARCHIVE" manual [1 (Related publications)]).
Backup volumes
The backup volume for logical data backup depends on the application profile in the Data Center. For example, the following values are available for the various backup types and quantities of backed-up data:
Full backup: complete active data set
Incremental backup: only files that changed since the last backup are backed up
The number of backup media required depends on the volume of the full and incremental backups and must be determined separately for each application.
