When Retention policy is set as REDUNDANCY
DB version: 10.2.0.4
Just trying to understand the concept of Redundancy.
If i set my Retention Policy set to REDUNDANCY like
CONFIGURE RETENTION POLICY TO REDUNDANCY 4;and all the backup files are stored in one location like '/u04/rmanbkp/' then multiple copies (4 of them) of the same datafile with different names (unique names generated using U% setting) will be created here. Right?
The next day all these datafile copies will be obsolete. Right?
Recovery Window retention policy is more widely used than Redundancy . Right?
on the 5th day,the first (out of 4 copies) copy of backup becomes obseleteprovided that you do exactly one backup every day. If you do 6 backups a day -- e.g. every 4 hours -- you'd be obsoleting a backup less than 24 hours old !
So, if you are DBA new to a site, ask first "how many backups we do, what is the RETENTION Policy" ?

Purpose of Retention Policy Recovery Window and Redundancy
Hi,
Good Evening,
I have some queries regarding the RMAN Retention Policy Recovery Window and Redundancy.
1. Any condition is there to set the Retention Policy Recovery Window and Redundancy and control_file_record_keep_time?What is the relationship between these 3 parameters?
2. Explain the scenario if i set the control_file_record_keep_time=4 Redundancy=3 and Recovery Window=7?
3. If i set the Redundancy=3 and Recovery Window=7 means my backup place only have 3 copies of backup based on the redundancy then what is the purpose of Recovery Window=7 please give some example.
4. If i change the values for Recovery Window=3 and Redundancy=7 what will happened, how many days backup will be available in my FRA location?Explain with one scenario?
Thanks in advance.
Vijay.Hi,
Take a look of the above doc contents:
Configuring the Backup Retention Policy
As explained in "Backup Retention Policies", the backup retention policy specifies which backups must be retained to meet your data recovery requirements. This policy can be based on a recovery window or redundancy. Use the CONFIGURE RETENTION POLICY command to specify the retention policy.
so you have option to choose either recovery windows or redundancy based you can set the configuration like
read in the Doc What it said for both:
Recovery Window-Based Retention Policy ==>RMAN does not consider any full or level 0 incremental backup as obsolete if it falls within the recovery window. Additionally, RMAN retains all archived logs and level 1 incremental backups that are needed to recover to a random point within the window.
Redundancy-Based Retention Policy==>The REDUNDANCY parameter of the CONFIGURE RETENTION POLICY command specifies how many full or level 0 backups of each datafile and control file that RMAN should keep. If the number of full or level 0 backups for a specific datafile or control file exceeds the REDUNDANCY setting, then RMAN considers the extra backups as obsolete. The default retention policy is REDUNDANCY 1.
RMAN> show RETENTION POLICY;
using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name DDTEST are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 3;
old RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
new RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO REDUNDANCY 3;
new RMAN configuration parameters are successfully stored

RMAN> show RETENTION POLICY;
RMAN configuration parameters for database with db_unique_name DDTEST are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONTROL_FILE_RECORD_KEEP_TIME:This parameter applies only to records in the control file that are circularly reusable (such as archive log records and various backup records) ref Doc:CONTROL_FILE_RECORD_KEEP_TIME
1. Any condition is there to set the Retention Policy Recovery Window and Redundancy and control_file_record_keep_time?What is the relationship between these 3 parameters?
2. Explain the scenario if i set the control_file_record_keep_time=4 Redundancy=3 and Recovery Window=7?
3. If i set the Redundancy=3 and Recovery Window=7 means my backup place only have 3 copies of backup based on the redundancy then what is the purpose of Recovery Window=7 please give some example.
4. If i change the values for Recovery Window=3 and Redundancy=7 what will happened, how many days backup will be available in my FRA location?Explain with one scenario?
so i believe you can get the Answer from Your Question from Above details.

Backup Set pieces 1,2,3,4 basically equate to my oldest backup - hence under redundancy of 2, I can see why that is obsolete
5 and 7 were simply Control File/SPFILE backups from Auto Backup and the 2 newer backups of these have been taken since ( i.e. backupset pieces 9 and 10 )
Q. What happens if I wanted to restore the database to the 27/09 ? What SPFILE and Control would it use ( presuming the OBSOLETE files had been removed out of the FRA ) ?
Would I have to restore the removed backup set into the FRA, Cross Check and then restore the database via RMAN to the 27/09 ?
Q. Why are some of today's ( 10/10/13 ) archive logs marked as OBSOLETE ?
Q. If I wanted to have the ability to restore the database to 2 days ago, is perhaps a Rentention Policy of a 2 day Recovery Window perhaps better than my current Redundancy=2 policy ( combined with taking a daily backup ) ?
any advice appreciated,

- Yes you can get the database to the date which ever you want , using recover database until time.
Q. Why are some of today's ( 10/10/13 ) archive logs marked as OBSOLETE ?
- can you please provide the output of below command
RMAN> show all;
Q. If I wanted to have the ability to restore the database to 2 days ago, is perhaps a Rentention Policy of a 2 day Recovery Window perhaps better than my current Redundancy=2 policy ( combined with taking a daily backup ) ?
- You can restore the database back to two days or 5 days based on your requirement. You nee to recover the database using until time option.

RMAN>Note: i have archivelog which is at FRA ,it also apply there and as well yours own defined backupsets path.
Yours comments are wellcome.
http://oraware.blogspot.com/2008/04/can-i-use-retention-policy-without.htmlKhurramHmmm, I can't see where the confusion originates. The table near the bottom of www.apple.com/timecapsule/specs.html has one row labelled "For backup using Time Machine" and another row labelled "For AirPort Disk with a USB hard drive".
The requirement for backup via Time Machine is OS 10.5.1 or better. Time Machine is not supported in pre-Leopard (OS 10.5) nor in Windows.
The requirement for using Time Capsule as a remote disk is identified as "Mac with Mac OS X v10.4.8 or later" or "PC with Windows XP (SP2) or Windows Vista; Bonjour for Windows (included on Time Capsule CD)".
Doesn't that pretty much spell out that Time Capsule works as a network drive without the need for Time Machine?
Also Joe (the OP) never indicated any desire to use it with Windows so I'm not sure why all the discussion about Windows compatibility. ??
Also the quote posted by Henry seems pretty clear:
"Time Capsule with Time Machine in Leopard is the ideal backup solution. But that doesn’t mean Tiger, Windows XP, and Windows Vista users can’t enjoy the benefits of Time Capsule, too. Because it mounts as a wireless hard drive, Tiger and Windows users simply access Time Capsule directly from the wireless network for exchanging and storing files quickly and easily." -
Control_file_record_keep_time vs retention policy
Its not thread nor question just read from documents and tried to imply the fact of documents and i think its written correct what i tried to do proof it practically ,neither i am trying to be smart just share with you guys is my observation correct or not.i am using FRA area for backup.
<quote>
Relation between RMAN retention period and control_file_record_keep_time
RMAN backup keeps the backup metadata information in the reusable section of the controlfile.Its depends on the parameter CONTROL_FILE_RECORD_KEEP_TIME. CONTROL_FILE_RECORD_KEEP_TIME specifies the minimum number of days before a reusable record in the control file can be reused.
In the event a new record needs to be added to a reusable section and there is not enough space then it will delete the oldest record, which are aged enough.
Backup retention policy is the rule to set regarding which backups must be retained (whether on disk or other backup media) to meet the recovery and other requirements.
If the CONTROL_FILE_RECORD_KEEP_TIME is less than the retention policy then it may overwrite reusable records prior to obsoleting them in the RMAN metadata. Therfor it is recommended that the CONTROL_FILE_RECORD_KEEP_TIME should set to a higher value than the retention policy.
Formula
CONTROL_FILE_RECORD_KEEP_TIME = retention period + level 0 backup interval + 1
For e.g.
e.q. level 0 backup once a week with retention policy of a recovery windows of 14 days then in this
case the CONTROL_FILE_RECORD_KEEP_TIME should be 14+7+1=22

RMAN retention policy will be applied to the command

no obsolete backups foundnothing obsolete it means control_file_record_keep_time will not affect backups unless it will be less then or equal
to retention policy.
Note : Please agree or disagree with me may be i would be wrong
KhurramSorry for alls readers after a long practical observation at my own database server i came across that my observation was wrong and absurd in this first post, the above observation is not due to control_file_record_keep_time ,its due to something obvious which i am going to share you guys here.
RMAN> show retention policy

RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;

RMAN>AS documentation says
"Besides affecting datafile and control file backups, the retention policy affects archived logs and archived log backups.
First, RMAN decides which datafile and control file backups are obsolete. Then, RMAN considers as obsolete all archived
log backups that are older than the oldest datafile or control file backup that must be retained."
Now i connect to SQL and create two big table for filling the redo log file and then get it archived.Please
consider it here that i am getting archived before any taking backup i.e backup database in order to make
archive older then the oldest datafile.

But this archivelog file will get obsolete if its beyond the retention policy,lest see how ,just take one more
backup ,as i have already taken two time backup and the moment i go to take third backup it will cross ours
retetnion policy from the period of 2.

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 0 DAYS;
Hi Guys
Can you please put some light on the 0 days. what is the meaning on 0 days and how does this work.
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 0 DAYS; If I take full backup every night how many backup will it contain and how will it obsolete the backup.
RMan 9i R2
Soalris 5.9
I understand the concept if recover window is 1 or more days but confuse with 0 days.
Thank you in advance.RECOVERY WINDOW OF 0 DAYS is effective like REDUNDANCY 1.

Retention policy for archivelogs in the flash recovery area
I am using the flash recovery area for all my backup files (archive logs, data and control files). I want to use the redundancy retention policy because it is easy to calculate the space requirement. However, I am not clear how the retention policy applies to archive logs.
Say I set the retention policy to be "keeping 3 backups". How does it affect the archive logs? Will archive logs in the flash recovery area be deleted automatically or I need to do it manually. If they are deleted automatically just like dataset files, what is the "retention policy" for them? I do not have a tape device so all archive logs are going to be stay in disk.
Thanks.I am using the flash recovery area for all my backup
files (archive logs, data and control files). I want

"Besides affecting datafile and control file backups, the retention policy affects archived logs and archived log backups.
First, RMAN decides which datafile and control file backups are obsolete. Then, RMAN considers as obsolete all archived
log backups that are older than the oldest datafile or control file backup that must be retained."
Now i connect to SQL and create two big table for filling the redo log file and then get it archived.Please
consider it here that i am getting archived before any taking backup i.e backup database in order to make
archive older then the oldest datafile.

Recovery window retention policy deletes archive logs before a backup?
Hi All,
Oracle 11G on Windows 2008 R2
This afternoon, I changed my RMAN retention policy from 'RETENTION POLICY REDUNDANCY 3' to RETENTION POLICY RECOVERY WINDOW OF 3 DAYS'
However, i checked tonight and after my daily backup ran, all the archive logs prior to the backup had been deleted! Thus meaning i dont think i can restore to any point in time, prior to my daily backup. All the .arc logs were there after the backup. So i tried another test and kicked off the daily backup again. During the backup process, the archive logs got deleted again! Now i don't have any archive logs..
Is this proper behaviour of RETENTION POLICY RECOVERY WINDOW?? I thought it would keep all the files needed for me to restore to any point in time for the previous 3 days. When i used REDUNDANCY, with my daily backups, it kept 3 days worth of backups+ archive logs so i could restore point-in-time to any point. How can i use RECOVERY WINDOW so that i can actually restore to any point-in-time for the 3 days??
I wanted to change to RECOVERY WINDOW since i read that by using REDUNDANCY it only keeps X copies of a backup (so if i ran the backup 3 times in a day, i would only have those 3).
Thanks in advance.Hi All,

Retention Policy and report/delete obsolete
The database is Oracle 9i on Solaris 8 Platform.
The backup of datafiles and archivelog files use tape and run every night.
The backups should be held for two weeks therefore using RMAN retention policy with REPORT / DELETE OBSOLETE will be the apropiate method. Unfortunatelly somehow none of the two methods of retention policy RECOVERY WINDOW or REDUNDANCY don't seem to work. The big question is WHY?
I configured the retention policy using:
CONFIGURE RETENTION POLICY TO REDUNDANCY 7
Then ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt;
I ran CROSSCHECK BACKUP with a correct output and then REPORT OBSOLETE. The report displays all existing backups - (SYSDATE-2)!
If using RECOVERY WINDOW OF 7 DAYS then the obsolete report displays the list of backups - (SYSDATE-1).
Somehow whatever number I use (7/9/5)in any of the retention policy the result is identical with the one above!Really I do not know if there is a limitation regarding that aspect if you take the backups in tapes directly. I have implanted and I have seen it function well when backups are store directly in disk.
Find out here if that is a limitation.

Retention policy vs. Archivelog deletion policy
Environment:
Oracle EE 11.2.0.3 on Solaris 10.5
Which policy takes precedence?
My Retention Policy is set to 'Recovery window of 8 days' and my Archivelog deletion policy is set to 'backed up 2 times to disk'.
My DAILY full backup happens at 03:00am and uses the following commands:
backup incremental level 0 cumulative database tag 'full_daily' plus archivelog tag 'full_daily';
DELETE NOPROMPT OBSOLETE;I also have an archivelog backup that runs every 4 hours at 02:00, 06:00, 10:00, 14:00, 18:00 and 22:00 and looks like this:
backup archivelog all tag '&1';
delete noprompt ARCHIVELOG UNTIL TIME 'SYSDATE-8';With the archivelog backup running every 4 hours the logs are getting backed up to disk the required 2 times very quickly. Much sooner than 8 days! :-)
I have a problem where the archivelog backup that runs immediately AFTER the full database backup fails due to not being able to find some older archivelog files.
In looking at V$ARCHIVED_LOG the files were dated (COMPLETION_DATE) just outside the 8 day retention window but they had a status of 'A' (Archived) instead of the 'D' (Deleted) I was expecting. When I ran a 'Crosscheck archivelog all' it changed the statuses to 'D' and the next archivelog backup ran successfully.
What am I missing?
Should I change the archivelog deletion policy to something else? If so, what and why (just trying to understand!) ?
I am not using an FRA and have controlfile autobackup turned on.
Please let me know if you need more information. I have been scouring the docs and the 11g RMAN Oracle Press book but haven't found the trick yet!
Thanks for any assistance!

Since you have 2 copies of ArchiveLogs in the backups and these are retained for 8 days, a "delete noprompt ARCHIVELOG UNTIL TIME 'SYSDATE-8';" is overkill. Why retain 8 days of archivelogs on disk if there are 2 copies already backed up ?
Does your full backup that begins at 3am complete before 6am ? If it goes beyond 6am, it will be deleting some files after 6am but the "backup archivelog all" at 6am will expect some archivelogs (8 days old) to be present.

Backup with retention policy to recovery window of N days
Hello,
I've issued command to create database incremental backup with configuration:
run
configure retention policy to recovery window of 14 days;
backup incremental level 1 cumulative
tag daily_incr_14_days
database
plus archivelog delete all input;
All parameters are set to their default values and database backups goes to FRA. I've got recovery catalog connected and all RC_ views at my disposal.
1) Is there any way to find out, what recovery window was used for backup from any command in rman or query from RC_ views or local database views (information from control file)?
2) If I use other recovery window setting with configure command what would rman crosscheck or report commands do?

Mahir,
thanks for answer - this means that recovery window should be used mainly for maintenance purposes (crosscheck, delete obsolete, report need backup etc.) and it's not related to actual retention period with backup pieces like 'keep until' clause for backup ... database command (this information are saved with backup as I could check in rc_backup_set view from recovery catalog)?
Yes it is.

backup retention policy
A user-defined policy for determining how long backups and archived logs must be retained for media recovery. You can define a retention policy in terms of backup redundancy or a recovery window.
RMAN retains the data file backups required to satisfy the current retention policy, and any archived redo logs required for complete recovery of those data file backups.
recovery window
A recovery window is one type of RMAN backup retention policy, in which the DBA specifies a period of time and RMAN ensures retention of backups and archived redo logs required for point-in-time recovery to any time during the recovery window.
The interval always ends with the current time and extends back in time for the number of days specified by the user. For example, if the retention policy is set for a recovery window of seven days, and the current time is 11:00 AM on Tuesday,
RMAN retains the backups required to allow point-in-time recovery back to 11:00 AM on the previous Tuesday.

Retention policy and deletion of archived files
hello, I 'am a novice DBA having a backup question.
Our retention policy is set to 14 days; weekly we have full database backup; daily we have an incremental backup.
See scripts below.
The drive "\\is003s012\rhea\rman" where the backup files reside has files older than 2 months.
I expected these files to be deleted already by rman.
I can't find the cause why these files are not removed.
The database backup jobs are running fine ; logs file do not contain any errors and once and a while you see that rman removes obsolete files.
list expired / report obsolete do not return any files.
thanks for the assistance

Thanks for the info; my current setting for this parameter:

I found another thread that elaborated on this: Re: CONTROL_FILE_RECORD_KEEP_TIME vs Retention Policy in RMAN
a) RMAN Retention Policy set to recovery window of 30 days means backups and archivelogs that you need to do a Point in Time Recovery to before 30 days do not get obsolete.
b) CONTROLFILE_RECORD_KEEP_TIME=7 will keep (potentially, if space pressure in the controlfile) the records of these files for only 7 days
Effect: Your old backups and archivelogs (+7 days) are no longer known by the system and will not get deleted (automatically or by delete obsolete) and your recovery area/backup location/archive destination will get filled up with old files.
Therefore set b) > a)
Based on this I changed the parameter:
alter system set CONTROL_FILE_RECORD_KEEP_TIME=35 scope=both;
Even tho the 'stale' backupsets are still invisible (still getting 'no obsolete backups found' when doing REPORT OBSOLETE), I guess that's because it will take a while (23 days?) for the CONTROL_FILE_RECORD_KEEP to catch up to the RMAN Retention Policy of 30 days)....

RMAN backups does not match its retention policy
Hello,
I have couple of PROD instances on Windows environment with 11.2.0.3 DB version. RMAN retention policy is set to 14 days but I have noticed that backup is showing longer than that.
For example: LIST BACKUP OF DATABASE whows backups since 13th October. I also checked backup pieces at netapp share and they are present.
DELETE NOPROMPT OBSOLETE do not remove anything as expired backup.
I have clear retention policy and set to 14 days again but does not seem to work.
I would appreciate suggestion(s) regarding the strange issue.
Thanks a lot.

We would need to know what kind of backups and when they were taken. Consider this scenario:
retention policy of 7 days.
Incremental level 0 backup taken on Sundays
Incremental level 1 backups taken Mon through Sat.
Let's say Oct 1 is a Sunday, so we take an inc-0 backup on Oct 1, and again on Oct 8.
Now let's say we are at Oct 10. Our 7 day retention policy dicatates that we be able to recover to any day back to Oct 3.
The only way we can recover to Oct 3 is to begin with that inc-0 backup from Oct 1.
All recovery begins with the last inc-0 backup prior to the point in time to be recovered. In a normal, regularly cycling schedule of backups, you will actually end up with backups 1 day short of being twice as old as your retention period.
Let's take a more extreme example. Same 7-day retention period, but after a single inc-0 backup, you don't take any more backups for 3 months. That one single backup is still needed to enforce your recovery window, and so is not obsolete, despite the fact it is 3 months old and your recovery window is only 7 days.
Also, you mention 'expired'. In terms of oracle backups, 'expired' is not the same as 'obsolete'.
"Obsolete" means 'no longer needed to enforce recovery policy'.
"Expired" is a bit more complex.
when a backup is taken, or an archivelog is written, a record of that is written to the repository. when you do an rman 'crosscheck', those repository records are compared to reality -- to see if the recorded backup file or archivelog file actually exists. Maybe someone used an OS command to delete them. Any file found to have 'gone walkabout' have their repository records marked as 'expired'. An rman 'delete expired' then removes those records from the repository. -

Retention policy for incremental cumulative backup question
Hi,
I have a production database configured with retention policy for 30 days window. No catalog is used.
The backup plan is:
Sunday - Level 0 backup.
Weekdays - Incremental 1 cumulative backup.
I also noticed that some archive logs since Mar 07 2010 has become obsolete in the recent few days.
Cannot figure out why the backup of Mar 07 2010 is going to be obsolete today.
Thanks for your help!
