Example: Restarting a failed NetBackup for SAP backup job (UNIX or Linux)
This example shows how to restart a failed backup job on UNIX or Linux. In this example, assume the following:
The backup job was deliberately cancelled from the activity manager. In a real user case, a job might fail for different reasons.
You enabled checkpoint (the option in the policy).
You ran the backup according to the following brbackup command:
brbackup -d util_file -t offline -m all -c force
The following is an excerpt from the output log:
BR0280I BRBACKUP time stamp: 2006-02-28 21.07.59 BR0057I Backup of database: SUD BR0058I BRBACKUP action ID: bdsbecnl BR0059I BRBACKUP function ID: aff BR0110I Backup mode: ALL BR0077I Database files for backup:
/oracle/SUD/origlogA/log1_m1.dbf /oracle/SUD/origlogB/log2_m1.dbf /oracle/SUD/origlogA/log3_m1.dbf /oracle/SUD/origlogB/log4_m1.dbf /oracle/SUD/saparch/cntrl/cntrlSUD.dbf
BR0061I 29 files found for backup, total size 853.604 MB
The previous output log shows the 29 files for backup. brbackup calls the NetBackup SAP agent for backup.
In this example, we have configured the checkpoint frequency for 5 minutes. By the time first checkpoint was taken (that is, in the first 5 minutes), 13 files were backed up. The user killed the job from the NetBackup activity monitor after NetBackup took the first checkpoint. backint returned #SUCCESS messages to brbackup for 13 files that were backed up. For the files that were yet to be backed up, backint retuned #ERROR. The following are the output messages from the brbackup log:

You can then restart the preceding job with following command:
brbackup -d util_file -t offline -m all -f last -c force
The brbackup command examined the last backup log and found that the backup failed for some files. It writes following messages in the beginning of output log for this session:
