With the BACKUP SYSTEM online utility, you can dump a
fast replication copy of a system-level backup to tape. You can then
manage the available disk space, retain the system-level backups,
and provide a means of recovery after a media failure.
Procedure
To dump a fast replication copy of a system-level backup
to tape that was taken without the DUMP option, or to re-initiate
dump processing that has failed:
- Identify the token (a 36 digit hexadecimal
byte string) in the DSNJU004 output.
- Create and run your utility control statement with the
DUMPONLY option. Specify the token if the system-level backup is not
the most recent system-level backup taken.
Restriction: Do not dump system-backups to the same tape that
contains image copies or concurrent copies because the RECOVER utility
requires access to both
- Run the DFSMShsm command
LIST COPYPOOL with the ALLVOLS option to verify that the dump to tape
was successful. The BACKUP SYSTEM utility issues
the DFSMShsm command
to initiate a dump, but it does not wait for the dump to be completed.
