Applying level 1 Incremental Backup (Abid)
Dear All
I have taken Prouduction database backup incremental level 0 from machine A
and restored in on Machine B ( another machine). Now i have taken incremental level 1 backup of Production with the following command,
BACKUP INCREMENTAL LEVEL 1 DATABASE;
Now i want to apply it on Machine B. Kindly tell me steps and command.
Thanks
What is the Machine B database doing? Is it a standby?

Level 1 incremental backup taking larger space
Hi All,
Yesterday i had level 1 incremental backup. Backup completed successfully but its size was as equal as Full Backup.
What could me the possible reason for that ?

Hi,
is the level 0 incremental backup a full backup ?
Thank you.Stellios wrote:
A level 0 backup is not the same as a full backup in that you cannot perform an incremental backup over a full but only over an incremental level 0. So for a large database this may affect your backup strategy (backup running overtime because of no level 0 to start with and implicitly creating one).
"A level 0 backup must exist as the base backup for an incremental strategy. An incremental backup at level 0 is identical in content to a full backup, but unlike a full backup the level 0 backup is considered a part of the incremental strategy. If no level 0 backup exists when you run a level 1 backup, then RMAN makes a level 0 backup automatically."
See INCREMENTAL LEVEL:
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta009.htm#i1009966
Correct.
Level 0 backup is not same as full backup because it's not possible to take level 1 backup after nonincremental full backup
Level 0 backup is identical in content to full backup because they both take backup of ONLY used data blocks
To show it, backup database as "full backup" and as "level 0 incremental backup" and check sizes:

Is a Level 0 Incremental the same as Backup Database?
hi experts,
This is a 10g database running in archivelog mode.
This is the backup scheme I'm currently using:
backup database plus archivelog; (runs once per day)
backup incremental level 1 database; this runs every 3 hours
(All the incrementals I make are level 1.)
In another forum, I was advised to make a level 0 incremental backup, because you cannot restore a level 1 if there was no level 0 made earlier. Now, I'm looking for the RMAN expert's advice :-)
** If I do this will I have what I need to be able to restore: **
- backup incremental level 0 database; (this will run once per day)
- backup incremental level 1 database; (this will run every 3 hours
In other words, will I miss anything if I dont do a backup database ?
Thanks, JohnIf you taking level 1 backup and If you dont have any level 0 then RMAN take hole database backup (level 0) with level 1 command.
It is always advisible to take level 0 and follow the level 1.
I advise to see the below doc which covers all your doubts and best way to backup.
Hope this solves your issue.

Hello Everybody.
I want to know the description of all 0-4 levels of incremental backups. Anybody please tell me in details.
Thanks and Regardsora-boy
Questions like this have version specific answers. Almost all questions have.
It is useless and silly to post any question without any version information.
Here's why
In 8i and 9i: incremental levels are between 0 and 3. There is nothing to explain,
1>0, 2>1, 3>2. That's all.
In 10g there is only 0 and 1. The higher levels have been removed.
Please stop asking questions without version information, assuming people keep track of your version (which we don't) or will summarize it for all available versions (which we won't )

Can we take Incremental backups without Level 0 backups
Kindly share the procedure if any by which we can initiate an incremental backup without Level 0 backup
Kindly share the procedure if any by which we can initiate an incremental backup without Level 0 backup
There is NO such procedure.
You can't 'increment' something that doesn't exist can you?
Please increment the previous number by 1. Can you do that? Of course not because there IS no previous number.
BY DEFINITION (see the doc) an incremental backup for any level but 0 REQUIRES a previous backup:
an incremental backup copies only those data blocks that have changed since a previous backup
A level 1 incremental backup can be either of the following types:
A differential incremental backup, which backs up all blocks changed after the most recent incremental backup at level 1 or 0
A cumulative incremental backup, which backs up all blocks changed after the most recent incremental backup at level 0
Incremental backups are differential by default. -
Restore Tablespace incremental backup is not work as after reimage oracle
TheTablespace incremental backup Restore is not work as after reimage the oracle database or restore tablespace in standby machine(another machine) is not working .its working in the same machine without reimage .after reimage not working please clarify me ,
I need the solution as soon as please reply as soon as .
Commnads used:
This is the step is followed but i am getting backup or control file not found error.Its works i the application server is not reimaged ;
please give your valuable suggestion .
Product Used:oracle 11g in linux environmnet
1)Before taking backup get SCN number for restore.
Command applied: Select current_scn from v$database;
2)running Full backup of database
Command applied:
configure controlfile autobackup on;
backup database plus archivelog;
CROSSCHECK BACKUP;
exit;
3)Running level 0 incremental backup
Before taking backup get SCN number for restore.
Command applied:
BACKUP AS COMPRESSED BACKUPSET INCREMENTAL LEVEL 0 TAG ='WEEKLY' TABLESPACE TEST;
exit;
3) Running level 1 incremental backup
Before taking backup get SCN number for restore.
Command applied:
BACKUP AS COMPRESSED BACKUPSET INCREMENTAL LEVEL 1 TAG ='DAILY' TABLESPACE TEST;
4)Before Restore(TSPITR) following procedure are applied under sysdba privilege
Command applied:
SQL 'exec dbms_backup_restore.manageauxinstance ('TSPITR',1)';
5)TSPITR Restore command
Command applied:
run
RECOVER TABLESPACE TEST UNTIL SCN 1791053 AUXILIARY DESTINATION '/opt/oracle/base/flash_recovery_area';
SQL 'ALTER TABLESPACE TEST ONLINE';
please calrfiy my following question:
1. After reimage(reinstall oracle database with application ).The aboove scenario is not working
2. After fullbackup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/) to repository because daily cleanup script will keep the data as sysdate -1 .
For fullbacckup we are currently copying entire (flash_recovery_area/dbname) database folder to repoistory.
3. after incremental backup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/..) to repository because daily cleanup script will keep the data as sysdate -1
For incremenatl backup currently we are copying (flash_recovery_area/dbname/backupset/<currentdate> and flash_recovery_area/dbname/autobackup/<currentdate>) folder to repoistory.
4.During restore we are copy entire things from repository to flash_recovery_area finaly apply the above mentioned restore command.
Tabelspace incremenatl restore is possible after reimage application server(fresh database)/another server with same database(standby machine) ....?
If we missing something in backup side please clarify me how to retore the tablespace incremental / level 0 tablespacae after reinstallion of server/another standby server.
Any information please let me know .I need the solution as soon as please reply as soon as .Try the Recovery Manager (RMAN) instead. This forum is for feedback about the 11g XE Beta.

RMAN - Incremental backup / NOARCHIVELOG / Restore & Recover Until Cancel
I'm testing out a weekly plan as follows:
Sun : Shutdown db, RMAN level 0 Incremental Backup
Mon-Sat: Shutdown db, RMAN level 1 Incremental Backup.
The database is NOARCHIVELOG mode and is 10.2 XE.
I then run a restore (which I understand to be to move the datafiles from the backup set to their online location). My next aim is to do a recover.
I'm really confused at this point. Say I take the backup the night before (either a level 0 or 1, I'm assuming that this makes no difference) then in the morning I drop a table accidentally. Okay - I want to go back to the position after the backup. When I do recover, I understand that Oracle applies redo logs written since the backup.
So I don't want a recover, I want a recover until cancel. When I issue this command it is suggesting that I use an archive log file. Well obviously I don't have any of those so I press cancel thinking that this will bring me back to the point EXACTLY AFTER THE NIGHTLY BACKUP and with my table back. But it doesn't!
I would be really grateful if anyone has a definitive answer to this - what are the steps to recover a database to the point after the backup was taken ignoring any changes since the backup.
Thanks all.
Tom.Hi Werner
Do you mean if the online logs are available with the changes after the last backup until the database restore then there is a possibility to apply changes? Ie at this point I could put in the redo log names instead of the archive log names.
If they have been overwritten since the backup (ie cycled round completely) then is the behaviour to restore the database and then not apply any logs?
Do you know if this is documented anywhere? There seems to be an emphasis on ARCHIVELOG mode only, especially in the books I have seen.
Thanks,
Tom -
Does it necessary to put the "plus archivelog" in incremental backup?
Hi
Because RMAN is using the archivelog to create the incremental backup , does it necessary to put the "plus archivelog" in backup command?VahidS wrote:

Please cite the documentation that says rman is using the archivelog to create the incremental backup.
Lacking documentation, please post a proof example.In your personal sandbox database, do the following:
1 - delete any existing archivelogs
2 - take a level 0 incremental backup
3 - generate a few archivelogs
4 - delete the generated archivelogs manually, using and os command
5 - take a level 1 incremental backup -
Configuring Incremental Backup
Hi there
I am designing RMAN backup
- I want to use Repository Catalog
- I want to take level zero backup every saturday night
- I want to take level 1 incremental backup everyday night, except sunday
- and I want jobs to be scheduled and I prefer not to use EM.
- I want to check for logical and physical corruptions before taking the backup
Q1. what is the place of archive log in incremental backup
Q2. should I include the archive log in level 0, in level 1 or in both
Q3. so can any one provide me with a sort of template scripts to help me start with
I know there are wide resources but I wanted a seed to build up on.
I appreciate any help
ThanksFirstly - you cannot backup archive logs at level 0 or 1. When you think about it archive logs don't change once they are created so why would you ever back them up with incremental level 1 besides there is no option to do this.
You can say however "backup incremental level 0 database include current controlfile spfile plus archivelog;" in one statement.
"You can delete the archive logs once incremental backup is complete. It is done automatically by using delete obsolete command."
Depends if that's what you want to achieve - I personally prefer to backup archive logs at least 3 times before deleting them (BACKED UP 3 TIMES) and also on seperate tapes. The balance is between available disk space for archive logs and requirements of the client. You would hate to compromise recoverability because of a few lost archive logs all backed up on one corrupted or lost tape.
You should also "sql 'alter system archive log current';" before the backup command to capture maximum data changes. -
What are the steps applying incremental backups to standby database 11g
Hi All,
I have built 11g none ASM standby database from ASM RAC Database. Now I want to apply incremental backup to the standby database from primary but not sure how to do it. I tried following and I had an error “ORA-01103: database name 'ins-prim' in control file is not 'ins-sec'”
1- I have configured standby database with RMAN backup.
2- After finishing installation, I took a incremental backup from primary server(ins-prim) and moved incremental backup and control file to the standby (ins-sec) database
3- I stared standby database nomount mode
4- restore controlfile from “incremental backup location in standby database”
5- alter database mount; and got this error
“ORA-01103: database name 'ins-prim' in control file is not 'ins-sec'”
What are the steps applying incremental backups to standby database with 11g?
Thank youI build the database from backup and changed from ASM to none ASM and changed location of data files and logfiles. I think this changes makes the standby database as logical one.
You can a have a physical standby with different locations for everything (redo/controlfiles/datafiles), ASM and no ASM etc. I have a such a configuration in production (10gR2)
I build the database from backup
Are you sure you have a standby ? Ins-sec receives the archivelog files from the primary ? How did you proceed to build this database ? I suspect you don't have a standby at all ! If you have duplicated the database ins-sec and ins-pri are independent databases and you won't be able to apply an incremental backup (your script was not correct but it is another story) -

Hi,
we are using oracle10g(10.2.0.3).
is it possible to apply rman incremental backup on top of manual full backup?
Note:There is no level 0 backup available
Thanks
With Regards
UmairYes, you can.
Register your manual backup in recovery catalog as level 0 backup. Then take a fresh incremental backup. I have demonstrated the same in my article. You may download the same from here .
Go through the section "Rolling forward a backup".

Incremental backup time query?
Database size = 270GB
Time taken for full level 0 backup = 50 minutes (Day 1)
Time taken for cumulative level 1 backup = 70 minutes (Day 2)
Time taken for differental level 1 backup = 55 minutes (Day 3)
My question is how come the incremental backup is taking more time than the full backup time?
Please advice.

Yes incremental backup is taken on the same time when there is heavy load on the system. For sure is this the reason? No, not for sure. We haven't seen enough info to say for sure, but given what we have been shown, it is a reasonable first guess. To know for sure, you need to do some actual performance analysis during both full and incremental backups and compare the two. STATSPACK is always a good place to start.
I will try the incremental backup at night when there is nobody connected.
Even though online backups <i>can</i> be taken anytime, it's always a good idea to schedule them during low-usage times.
But one more question when in case if there is a 24/7 system, then its no use of taking incremental backup right?Why would you think that? If your system is 24/7, that's even <i><b>more</b></i> reason to be taking incrementals. If you do have to perform a recovery, having incrementals will shorten your recovery time, vs. haveing to apply all archived redo back to the last full backup.
Also, you should be taking regular full backups as well. Most people take a full backup weekly, and an incremental on the other 6 days of the week.
As an additional thought .... while it is a curiosity that that your incremental took longer than the full and much could be learned by chasing it down, you always have to ask "is this a problem that needs to be solved?" If you schedule all backups (full and incremental) during low-use times, and the users do not notice any impact, do you really care if the incremental took longer than the full? On the other hand, it may <i>not</i> be a problem that "needs" to be solved, but running it down may reveal other problems that are impacting or have real potential to impact the business, and <i>should</i> be solved. -
Restoring incremental backup in QAS_ECC6_Ora_10G_Unix
Dear All,
We have restored PRD data in QAS about 4 months back upto 2009. Now we wish to restore the production data for the months of Jan to Apri;2010 in QAS. We can not afford restoring PRD whole data in QAS as it is more than 1.5 TB and it will take at least 3 to 4 days. We have the incremental databackup for these months with us (RMAN backup). Even we do have archive logs for this period.
Is it possible to apply archive logs in QAS (database open state), I believe we can not do this once we open the database.
How to restore incremental backup in QAS?
Thanks
S@pm@nHi,
Is it possible to apply archive logs in QAS (database open state), I believe we can not do this once we open the database.
Yes , you are right , you can not apply redo logs once database is open.
For restoring incremental backup also you need 0 level database restore first(You can not restore incremental backup of PRD directly on QAS) , so every case you need to restore almost 1.5TB of data.
Regards,
