Incremental updated RMAN backup help 11gR2

Dear all,
My manager ask me to build RMAN scripts to backup the 11gr2 database in redhat Linux.
Any help how to achieve this using RMAN?
thank you

I am not asking you to write a script. I can write it by myself.
What I need to know:
1- Incremental level 0 is a must in my case or I can just use the command below and it does everything (Level 0 , level 1 and level 0 incrementally updated)
backup incremental level 1 for recover of copy tag 'ALL_BACKUP' database;
2- The TAG must be unique every week, or can be always "ALL_BACKUP" ?
3- Which retention period is adequate in my case? 8 days are ok ?
4- Should I update the CONTROL_FILE_RECORD_KEEP_TIME to more than 7 days?
thank you

IMac OS X Lion update and backup help needed

Hello have a few questions I really need answered, so thank you for looking a this discussion.
1) I have a Mac OS X Version 10.4.11 2.16 GHz Intel Core 2 Duo. I'm hoping to upgrade to the OX S Lion now in July, so that means I need to back up my data right? My real question is will the Time Capsule work with the operating system I have now? Also which one should I get? I have around 100 GB worth of pictures, music, and video.
2) Will OS X Lion even work on the computer I have now or is it too old?

1. Yes, you should backup. Before you do you should do the following:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Backup your computer in some way. Use Time Machine or use Disk Utility's Restore option to clone your HDD:
Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
2. Lion will most certainly run on your computer. Requirements are a Core 2 Duo or better, 2 GBs of installed RAM, and 8-10 GBs of free space on the hard drive.

Incrementally Updated Backups -- do you Backup to TAPE ?

Incrementally Updated Backups on disk provide
a. only a single image of the database
b. as of only a particular point in time (the last incremental update)
c. no protection against disk/storage failure as the backups are on the same server as the database
Your Incrementally Updated Backups should go to Tape or to another Disk Area on another server or Virtual Tape Library frequently.
You may find the need to "restore and recover the database as of 3 days ago OR as of the last critical processing date" which cannot be done if you incrementally update your backup every day.
A backup on disk doesn't protect you from disk failure.

Incrementally updated backup and EMC NMDA

Hello Everyone,
I'm kind of a newbie in setting up networker module for oracle, to backup database to tape. We use the oracle's suggested backup strategy to backup DB to Disk first using the incrementally updated backups with recovery set to 3 days (RECOVER COPY OF DATABASE WITH TAG ... UNTIL TIME 'SYSDATE-3') , which helps us to recover DB to any point in time using the backup files in disks vs. going to tape. After backup to disk, we backup recovery area to tape nightly. However, we do want to maintain backup Retention Policy of 1 month. Couple of questions,
1. If i set RP to recovery window of 31 days in RMAN, then backups don't obsolete at all. this forces me to set RP in networker and they don't recommend setting RP in both RMAN and networker. how is this done generally to obsolete backups from tape as well as rman (catalog in CF) with above strategy. perhaps in this case i should set RP in netwoker and set RP in RMAN to none and rely on crosscheck and delete expired commands to sync with RNAM catalog.
2. Wondering if nightly backup of recovery area to tape is going to take incremental from previous day and NOT full backup. The reason i ask is, i do not want the tape to do full backup of FRA every day cause full backup datafiles change once in 3 days based on the until time set. is there an option do set in networker to do incremental only or that's the default.
Thanks in Advance!

You do a full backup of the FRA on tape ?No, I do a full backup of the database on tape. Using RMAN together with Veritas NetBackup.
I mean if you use incremental updated backup it'll not work on tape... Because the level 0 backup that will be updated with the backup of the day after will be on tape and will not be updated.The incrementally updated backup is in the FRA only, on disk (both the image copy and the following backup sets that are used for recovery of the image copy). Never gets written to tape or updated on tape.
Why don't you use then normal incremental backup ? That will have no problem with the tape backup even if level0, or level1,2 becomes reclaimable... ?I think I do :-)
Maybe:
To keep that you can put the redundancy to 2 out of 1 copy. Like this even with one copy on disk and tape it'll say keep the 2 copies.
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;I'll think about that.

Differential Incremental Backup or Incrementally Updated Backup?

DB Version:11g
DB Size:450Gb
DB type: OLTP (storing retail warehouse transactions)
To implement a proper backup strategy, we are currently weighing the Pros and Cons of Differential Incremental Backup and Incrementally Updated Backup.
I understand that , for Incrementally Updated Backup , the level 0 backup must be stored in FRA. We don't want to configure FRA as of now.
Which backup strategy would you choose for a similair environment?

I don't think that 11g RMAN level 0 backup need to use FRA: can you provide us the link to Oracle doc ?
When designing your backup strategy you need to define:
RTO: recovery time objective
RPO: recovery point objective.
See http://download.oracle.com/docs/cd/B19306_01/server.102/b14210/hadesign.htm
To meet a low RTO objective, you may need to use incrementally updated backup because it should be faster to recover from incrementally updated backup compared to differential incremental backup.

ESTIMATED RMAN BACKUP SIZE:::PLZ HELP ME

Hi all,
I wish you all happy new year :)
I have implemented a new Backup STrategy with RMAN, such I using Oracle 10G version on Linux Server. I would like To know if exists one method to estimate the size of my full and incremental backup before to lunch? I will really apreciate your help :)
Thank you all,

Hi,
Happy new year for you too!!!
From Metalink Note:105208.1:
There is no 'magic' formula to calculate the storage space of an RMAN backup
and there is no query that will give you a space estimate.
So, the best answer is: "Try it and see how much is used."
Check These out:
1-) https://metalink.oracle.com/metalink/plsql/f?p=130:14:4138343222012115291::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,105208.1,1,1,1,helvetica

Concept about Incremental Updated backup

I am going through Backup portion of Oracle. However, I am not able to understand the concept about the incremental Updated backups, its advantages and disadvantages.
Can anyone here help me out to get my concept clear.
Thanks in advance .

Block Media Recovery and RMAN Incremental Level 1 backup

Hi
I have read somewhere that Block Media Recovery will not work if a database is backed up using rman incremental 1. Is this true, and if so is there a work around?
I cannot seem to find this in oralce's documentation.
Regards
Me

Hi,
1) is Full Backup = Incremental level 0 backup?
Yes
2) When oralce say BMR does not work with incremental, will it work in the case I put forward. becuase Im doing an incremental 0...
But does you have the Archive logs available.. ?? If yes then it will Support.
3) Im my case will BMR work...that is use Incr level 0 on Sunday and then use archive logs for mon, tues etc
Yes, I believe.
@Hemanth .. am I right.. ?? Wait for your inputs...

If RMAN incremental level-1 backup fails...

Hi there,
I have a question. If the RMAN incremental level-1 backup fails, will the next level-1 backup attempt take backup of all changes since last successful level-0 OR level-1 backup?
Best regards

Hi,
I have a question. If the RMAN incremental level-1 backup fails, will the next level-1 backup attempt take backup of all changes since last successful level-0 OR level-1 backup?
Check the V$BACKUP_SET dictionary to confirm whether the last backup has been touched by data dictionary. If the failed incremental backup is picked up then the previous incremental backup will be required in case of the next DIFFERENTIAL INCREMENTAL LEVEL 1 backup.
But to be on safe side , it is recommended you take a LEVEL 01 CUMILATIVE INCREMENTAL backup from Level 0 till date. So that the recovery process can go through even if the previous backup is not valid.
Thanks &
Best Regards

I have a feeling this has been up here a lot. I updated ios 6 to my phone with no problems but I also back my phone up. I decided to help the wife out and update hers and something went wrong data lost. All contacts, photos, etc without backup, help.

I have a feeling this has been up here a lot. I updated ios 6 to my phone (4S) with no problems but I also back my phone up. I decided to help the wife out and update hers and something went wrong data lost. All contacts, photos, etc without backup, help.

if you have no back up in icloud or itunes the best you can do is sync with your computer and get back what you can from there

RMAN Incremental Lvl 0 backup vs Full Backup

Hi all professionals,
If my RMAN backup script did not specify the incremental backup strategy, what is the default strategy it would adopt?
say for example: backup as compressed backup set database plus archive log delete input;
Will it use full backup or lvl 0 incremental backup?
There is a RMAN script (similar with the above) running as scheduled job daily and I will also use backup exec to backup the database to tape (manually scheduled to run for each time but not daily) at the same time.
Will the scheduled daily rman script backup affect the scn of the backup using backup exec so that it could not be restore the tape backup using backup exec to a testing db as usual?
(checked that backup exec also use rman script to backup but it uses incremental lvl 0)
Welcome your professional comments and sharing.
Thanks,
Calvin

The only difference between a level 0 incremental backup and a full backup is that a full backup is never included in an incremental strategy.

Please, help with Incremental Update for Linearized document.

Hi, here is my problem.
I'm working in my own annotation app. It incrementally updates pdfs. Works fine with most of the pdfs.
But i've found couple of pdfs, that was being corrupted after updating.
Here goes more details:
Single page-linearized pdf: when i've looked into pdf source, i found that page object has /Parent key which referencing to non-existing object. Normally, as i understand /Parent for page object is /Type /Pages objects with /Kids /Count etc.
12 0 obj
<</ArtBox[26 0 585.999 792]/BleedBox[26 0 586 792]/Contents[14 0 R 15 0 R 16 0 R 17 0 R 18 0 R 19 0 R 20 0 R 21 0 R]/CropBox[0 0 612 792]/MediaBox[0 0 612 792]/Parent 8 0 R/Resources 37 0 R/Rotate 0/TrimBox[26 0 586 792]/Type/Page>>
endobj
Parent 8 0 R - Is missing
But all pdf viewers are ok with that.
So, this pdf has two Xref tables:
36 0 obj
<</DecodeParms<</Columns 4/Predictor 12>>/Filter/FlateDecode/ID[<2C9B406A12A771465F8FE0D6A4DC67ED><9B829DD8BDB09849A00CA5D75E7 5CDF4>]/Index[10 54]/Info 9 0 R/Length 114/Prev 66739/Root 11 0 R/Size 64/Type/XRef/W[1 2 1]>>stream....
and Second one at the end of file.
5 0 obj
<</DecodeParms<</Columns 5/Predictor 12>>/Filter/FlateDecode/ID[<2C9B406A12A771465F8FE0D6A4DC67ED><9B829DD8BDB09849A00CA5D75E7 5CDF4>]/Info 9 0 R/Length 51/Root 11 0 R/Size 10/Type/XRef/W[1 3 1]>>stream
Linearized dict:
10 0 obj
<</Linearized 1/L 67043/O 12/E 48239/N 1/T 66738/H [ 534 185]>>
endobj
/T 66738 points to Xref table in 5 0 obj's stream
Now, when my annotation is stored: i'm adding the following object to the end of file:
8 0 obj <</Type /Pages/Count 1/Kids [ 12 0 R ]>>
endobj
I've create the missing 8 0 obj with Kids and /Count 1
12 0 obj<</Type /Page/Annots [ 65 0 R ]/ArtBox [ 26 0 585.999 792 ]/BleedBox [ 26 0 586 792 ]/Contents [ 14 0 R 15 0 R 16 0 R 17 0 R 18 0 R 19 0 R 20 0 R 21 0 R ]
/CropBox [ 0 0 612 792 ]/MediaBox [ 0 0 612 792 ]/Parent 8 0 R/Resources 37 0 R/Rotate 0/TrimBox [ 26 0 586 792 ]>>
endobj
it's page objects with new Reference to Annotation object which is:
65 0 obj<</Type /Annot/Contents (Test 2)/M (D:20120507172231+03'00')/Open true/P 12 0 R/Rect [ 0 0 100.000 100.000 ]/Subtype /Text/T(Test 1)>>
endobj
then goes my xref table
xref
8 1
0000067045 00000 n
0000067189 00000 n
0000067591 00000 n
trailer
<<
/ID [ <FE1185EC7443D19473E8A4A1569A1CB2> <FE1185EC7443D19473E8A4A1569A1CB2> ]
/Info 64 0 R
/Prev 66739
/Root 11 0 R
/Size 69
>>
startxref
67760
%%EOF
And this totally broks my PDF.
Questing: /Prev in my trailer should point ot 5 0 obj or 36 0 obj?

Ok, thanks, and /Pref in my trailer should point to which xref? 5 0 (and the end of the original file) or 36 0 at the beginning?

Tracking RMAN Backup job details

Version:11.2.0.3/Solaris 11
To track RMAN backup job details , what dictionary view/dyn.performance view do you use ?
In our shop , we use incrementally updated backup (incremental merge). To find the details of previous RMAN Jobs, I tried using
v$rman_status
and
v$rman_backup_job_details
But the details provided by these 2 views don't match. For example, on 26th of June 2013, there was an Incremental backup and an archivelog backup. As per v$rman_status , both of them took 61 minutes (46 + 15)
According to v$rman_backup_job_details, backup jobs took 96 minutes .It doesn't seem to provide all info on archive log bkp though.
The start_time and end_time provided by both of these views don't math either !
col starttime format a25
col endtime format a25
select status, object_type, to_char(start_time,'dd/MON/yyyy:hh:mi:ss') as starttime,
to_char(end_time,'dd/MON/yyyy:hh:mi:ss') as endtime ,
to_number(end_time-start_time)*24*60 duration_minutes
from sys.v$rman_status where start_time > trunc(sysdate) - 20 and operation = 'BACKUP'
order by end_time desc;

When I run an full/incremental backup with archivelog it only shows as one job in v$rman_backup_job_details. Only if I explicitly run just a backup archivelog all in RMAN does it show up separately as an ARCHIVELOG backup in v$rman_backup_job_details.
rman_status shows the individual parts of the jobs. For example for a full backup it shows the db backup and the archivelog backup.
The start and end time in rman_status should match up with $rman_backup_job_details.
Lets take the 25th as an example:
In man_backup_job_details
STATUS                  INPUT_TYPE    STARTTIME           ENDTIME             DURATION_MINUTES

In v$man_status:
STATUS                  OBJECT_TYPE   STARTTIME                 ENDTIME                   DURATION_MINUTES
COMPLETED               ARCHIVELOG    25/JUN/2013:06:50:55      25/JUN/2013:07:58:01                  67.1

You need to view your logfiles to see what rman was doing between 6:00:08 when the job started and 06:25:06 when the incremental backup started.
You can see that the end time is the same in both views.
Not easy to explain but I hope that helps.

When you performing RMAN duplicate why you making your script so complicated?
Your instance name and DB name can be different, But what is the contents in your pfile "D:\TESTDELETE\initclonedb1.ora" ? please do post
Have you started any other services related to ORACLE? check in start --> run --> services.msc any other active oracles services, Make sure you have clonedb1.
Startup in nomount
check the connectivity to target server.
SET NEWNAME FOR TEMPFILE 1 TO 'F:\app\HOME\oradata\clonedb1\TEMP01.DBF';Why you mentioning SET NEWNAME FOR DATAFILE ? You have option of db_file_name_convert/log_file_name_convert in case if your file system different in Target & auxiliary.
BACKUP LOCATION 'F:\app\HOME\flash_recovery_area\orcl\'When you have backup in same location why you are mentioning this clause?
First run duplicate from auxiliary server as
rman target sys/*****@prod auxiliary /
RMAN> duplicate target database to "db_name";
Am not sure what you are trying to do. is it 11gR1 or 11gR2?
You have option of duplicate from active database without having backup also..
here some links please check it.
