-c|-confirmThis BRBACKUP command option backs up in unattended mode. This option suppresses most of the confirmation messages normally displayed during the execution of a backup. This enables you to run the program in unattended mode.
Syntax
-c|-confirm [force]Default value: confirmation messages are issued and user entry is expected.
Possible values:
-c|-confirm
This option suppresses most of the confirmation messages normally displayed during the execution of a backup. This enables you to run the program in unattended mode.
However, -c|-confirm
does not suppress the following confirmation messages:
Interactive password entry. To schedule a backup using CRON, use an appropriate script for entering the password. See Unattended Backup.
Prompt to mount the next volume, when more volumes are required than there are backup devices available. When a new volume must be mounted in the backup device during the backup, the utility responds as follows:
When a console is available, you can mount the next volume, make the entries required by the utility, and continue the backup.
When no console is available (the backup was scheduled using CRON or the CCMS, for example), the backup terminates with errors.
Example
A backup is scheduled using CRON. Three tapes are required for the backup. Two tape devices are available and you have mounted two of the requested tapes. The backup is started, but is terminated once the two tapes have been written.
Prompt for mounting the next tape when a cpio
continuation tape is requested – see cpio Continuation Tape. The backup is started. When the physical end of
tape is reached, the utility responds as follows:
When a console is available, you can mount the continuation tape, make the entries required by the utility, and continue the backup.
When no console is available (the backup was scheduled using CRON or the CCMS, for example), the backup terminates with errors.
force
When you specify the -c force
option, you also suppress the following confirmation messages:
Prompt to mount the next volume. When more volumes are required than there are backup devices available, the backup is not even started.
Prompt to mount a cpio
continuation tape. If a continuation tape is required, the backup is terminated at this point, and an appropriate cpio
error message is displayed.
However, -c force
does not suppress the following confirmation prompt:
Interactive password entry. To schedule a backup using CRON, use an appropriate script for entering the password. See Unattended Backup.
Note
To run the SAP utility with, for example, the UNIX utility CRON, use the option -c force
