Oracle - RMAN Backup Policy with KEEP
Our RMAN Obsolete is not working, the utilization ratio of backup file system reaches 90% percent. The former DBA uses his own script to choose backup set to delete, and they also use “find +mtime” and “rm” to delete backup.
It is very dangerous, especially then OPTIMIZATION is ON and there is a read only tablespace or pluggable read only database like ‘PDB$SEED’. RMAN only backup them one time. If the backup piece are removed without crosscheck, they is no backup for them anymore.
I redesign the backup and obsolete policy, depends on our requirement.
- Backup retention window is 7 days.
- Every week do a level 0 backup with 6 level 1 or 2 backup.
- The first level 0 backup each month needs to keep 1 year.
- The level 0 backup for every week needs to keep 5 weeks, but level 1 and 2 doesn’t need.
I am using KEEP UNTIL to achieve the long term keep policy. But, we needs to know what the keep exactly does: 1.The backup database with KEEP will backup the archive log which needed for recovery to consistent situation, controlfile, spfile and even the read only tablespace automatically. We don’t need to backup them especially.
using channel ORA_DISK_1 backup will be obsolete on date 01-APR-19 archived logs required to recover from this backup will be backed up channel ORA_DISK_1: starting compressed archived log backup set channel ORA_DISK_1: specifying archived log(s) in backup set input archived log thread=1 sequence=1202 RECID=1201 STAMP=996374548 channel ORA_DISK_1: starting piece 1 at 01-JAN-19 channel ORA_DISK_1: finished piece 1 at 01-JAN-19 piece handle=/u01/app/oracle/backup/O12201/ora_df996374548_s3121_s1 tag=20180101010000_LEVEL0_MONTHLY comment=NONE channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01 using channel ORA_DISK_1 backup will be obsolete on date 01-APR-19 archived logs required to recover from this backup will be backed up channel ORA_DISK_1: starting compressed full datafile backup set channel ORA_DISK_1: specifying datafile(s) in backup set including current SPFILE in backup set channel ORA_DISK_1: starting piece 1 at 01-JAN-19 channel ORA_DISK_1: finished piece 1 at 01-JAN-19 piece handle=/u01/app/oracle/backup/O12201/ora_df996374550_s3122_s1 tag=20180101010000_LEVEL0_MONTHLY comment=NONE channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01 using channel ORA_DISK_1 backup will be obsolete on date 01-APR-19 archived logs required to recover from this backup will be backed up channel ORA_DISK_1: starting compressed full datafile backup set channel ORA_DISK_1: specifying datafile(s) in backup set including current control file in backup set channel ORA_DISK_1: starting piece 1 at 01-JAN-19 channel ORA_DISK_1: finished piece 1 at 01-JAN-19 piece handle=/u01/app/oracle/backup/O12201/ora_df996374551_s3123_s1 tag=20180101010000_LEVEL0_MONTHLY comment=NONE channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01 Finished backup at 01-JAN-19
2.The incremental level 0 backup with KEEP cannot be used as the baseline of level 1 and level 2, due to it is out of retention policy. You will see an information “no parent backup or copy of datafile 1 found”, and RMAN will take an level 1 backup as level 0. And this backup will be used as the baseline of all level 1 and 2 forever after, if there was no another backup without keep. So a separate level 0 backup is needed.
Incremental Level 1 Backup Taking a Level 0 Backup Although Previous Level 0 exists (Doc ID 2023948.1)
using channel ORA_DISK_1 backup will be obsolete on date 08-JAN-19 archived logs required to recover from this backup will be backed up no parent backup or copy of datafile 1 found no parent backup or copy of datafile 3 found no parent backup or copy of datafile 4 found no parent backup or copy of datafile 7 found no parent backup or copy of datafile 6 found no parent backup or copy of datafile 5 found no parent backup or copy of datafile 8 found no parent backup or copy of datafile 10 found no parent backup or copy of datafile 9 found no parent backup or copy of datafile 11 found channel ORA_DISK_1: starting compressed incremental level 0 datafile backup set
3.If the database has read only tablespace and optimization is not set to ON, the all backup set of read only tablespace cannot be obsolete with recovery window policy. We need to use redundancy policy.
The following is my test script on VM. We have to disable VM to synchronize time automatically in advance.
For testing, I only keep monthly backup for 90 days and weekly for 32 days.

To display, I just show the backup of HR. We can see there is:
- 3 MONTHLY backups for April, May, and June
- 3 WEEKLY backups - the backup of June 1st is MONTHLY.
- 1 level 0 daily plus 6 level 1 daily.
