Full backup to optimize backup RMAN

Hi gurus,

I wanted to implement the functionality of rman backup optimization. I did a little test to verify its use and not found helpful whenever I do a full backup to backup all data files and nothing is ignored.

According to the ORACLE notes as below, ideally, once I backup the database, the backup else should jump not all files.


If you enable Backup Optimization and then the BACKUP command ignores backup files when the identical file has already been saved on the specified device type.


Please note that it's my test server and no connections are on the DB. Listener is broken. If no point of change Yvert. I'm missing here something?

Hi Tom,

Well well, then that contradicts what oracle mentioned in the docs?

Not at all.  It does that contradict your understanding of what constitutes a data file "changed."

Also, I pulled data backup and not backup tablespace.

Is not serious. The principle is the same.

Also check your statement my understand that if there are 100 files of data and rarely used, Yvert will be updated for each of them?

If they are not unalterable, then Yes.  That's how oracle ensures consistency between the data files.

Kind regards

  • RMAN how to handle simple full backups every day with the archivelogs



    Hello

    My use of Oracle DB is about 200 GB on a file system 1 TB from a NetApp file server. (i.e. 20% currently use)

    I'm not so attracted to use the RMAN catalog for the love of simplicity.

    Also, I have an affinity to run a full backup "Instant NetApp" every day, without running all the incremental backups.

    My snapshots of NetApp have a framework for the retention of 7 days.

    I think to implement a RMAN full backup script that includes the following to run every night:

    Run {}

    delete archivelog all;                    (to clean up the archive logs that are accumulated for each day)

    backup database;                          (for a full backup every night)

    }

    This will be a good idea?

    Will this coverage to back up all that I could restore if there is a problem.


    Part of the great mystery for me is on the restoration of the data that is generated during the execution of the "backup database" command in the RMAN.

    Any advice would be appreciated.

    Thank you!

    -Steve

    If you perform the backup in this order, you will get in big trouble.

    It is preferable to run the backup as follows:

    (1) the following parameters, you have to do only once:

    configure backup optimization

    Configure retention policy to recovery of 7-day window;

    Configure controlfile autobackup on;

    (2) backup every day:

    backup database more entered archivelog delete;

    delete noprompt obsolete;

    unrecoverable report;

    RMAN automatically takes care of cleaning the old backups<7 days="" and="" saved="">

    Hi all

    I dropped one of the user of our existing OEM repository database.
    I want to restore it from the backup rman I know you cannot restore only 1 user in the rman.
    I have not any expdp for users.
    can I use rman restore time and recovery point
    Please guide me with step by step restoration.
    also only the user schemas has been deleted and not the tablespace or anything like that.
    No flashback created restore point.

    Thank you

    Hello again;

    The binaries would be the Oracle software. This will not affect that.

    Make a full stop and then the four commands that I listed before replacing your Date / time.

  • RMAN full backup - size SPFile Total 0.00 K

    Hello, I do some tests and I need help to understand if there is something wrong in what I'm trying to do (a full backup with RMAN, DB is 11 GR 2).

    If I perform a simple full DB Backup, all past file and it completes successfully. No errors.

    Controlfile Autobackup is enabled, so I expect to find the control file and SPFile included in the backup, too.

    But if I go to Console 'EM-> availability-> backup reports

    It is reported the following:

    Looks SPFile size on backup is '0' and not what I was expecting (SPFile is actually being used and it is not empty).

    Should what kind of verification I do to see if everything is OK? Maybe a non-destructive.

    Thank you very much!

    Hello R,

    (1) the SPFile will be restored in a custom location / name of my choice ("spfile_restore.ora")
    which may be different from the ACTIVE SPFile

    I would say that must be different from the current spfile...

    (2) the SPFile ACTIVE will always be in place and will always be that "in use" even after restoring

    Correct the restored spfile will not be part of any oracle process.

    When you use the OEM GC configuration for running a scheduled backup, OEM GC run an RMAN session. You will not be able to change this option by inserting the shell commands.

    What you could do, is have the OEM GC to create the RMAN script for you (or creat it yourself), store the RMAN script in your catalog RMAN and create a BONE type Job. In this job, you can run a shell script, which first start RMAN session and run the RMAN script stored, that you created, and then run your command "tar".

    You can even think to do that with a multi step employment type, so that if your RMAN defective stage, you do not want the step of tar to execute.

    It contained a real data file? Or was it a backup controlfile? A backup controlfile may be outdated if another backup controlfile does not capture the same information it contains.

  • UNDO Tablespace backup-RMAN

    Hi/team champions,
    I'm confused in full DB Backup RMAN why CANCEL tablespce is included even we include also archive logs.
    in a Word?
    Why UNDO tablespace backup is necessary while taking backup RMAN?

    Kind regards
    Shitesh Shukla

    If I do not want to include the UNDO tablespce in my backup

    What happens if I took only backup files except CANCELLATION n TEMP

    NOT an option. You must include UNDO. 11g has optimization in order to safeguard an Undo tablespace.
    10 gr 2 what you pourriez do is

    1. create a new Undo Tablespace
    2. position yourself in the new Undo Tablespace
    3. check that the old Tablespace Undo is no longer in service - confirm that there is no transaction active in the inside undo segments
    4. remove the old Undo tablespace
    5. start your RMAN backup

    You run the risk of
    a. wait long to step 3
    b. ORA - 1555 s for users once you drop the Undo tablespace to step 4.

  • backup rman design database with phsical ensures

    Hello

    12 c database, after physical expectation is created, I need backup rman configuration,

    The goal is: a) backup of database b) remove archivelogs that have been backed up, free up space FRA.

    Design as below:

    1:

    in RMAN (primary and standby):
    RMAN >
    Configure controlfile autobackup on;
    set the type of backup device type disk compressed backupset;
    CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;


    2: primary school:
    RMAN > CONFIGURE RETENTION POLICY to the 5 DAY RECOVERY WINDOW;

    3: in priamry, turn on track changes to block

    4: primary, implemented since rman level 0 (full backup) on Sunday.

    5: in the primary, the installation program rman level 1 backup from Monday to Saturday.

    6: primary, set up since rman "save archive backup delete them all obsolete" every hour;

    questions here:

    1. as in step 5, for the protection of the o and delete archivelog, the script using:

    Run {}
    allocate channel d1 type disk;
    SQL 'alter system archive log current';
    overlap archivelog all;
    backup AS COMPRESSED BACKUPSET archivelog all delete them all input;
    output channel d1;
    }

    I wonder if ' archivelog all delete all entries "will delete archivelog which was not taken on the eve of the database and broken standby database

    (hanging and out-of-sync with primary)... it is a concern, is that possible?

    2. If the primary database crashed, failover to standby mode, then restore/recovery primary, switch back to the primary, this design is just? If you have any good suggestions, please let me know.

    (to put it simply, I don't want to full/incremental backup to install standby, primary server CPU is good enough)

    Thank you very much!

  • Backup RMAN when FRA is configured

  • Help remove backups rman (delete the repository)

    Hi all.

    I will soon be administering a few databases Oracle (11g Rel2). Currently these DBs area in log mode archive with a backup rman in place policy.


    I don't like this policy and you want to use my own, incremental backups from updadateable, so this is the plan I have in mind.


    (1) disable mode archive.


    (2) a clean shutdown and take a backup to cold.


    (3) since after you disable archiving, backups RMAN ALL will be unusable, I want to remove them (including newspapers archive and backup sets).


    (4) after the correct deletion, set up some persistent RMAN settings, such as retention policy, controlfile autobackup and optimization.


    (5) turn on archiving


    (6) to set up the new policy based backups backup incremental updateable with duplex location for archiving logs.


    Help is requested on the best way to clean all the backups (3).


    I can manually delete the backups and do overlap, but according to the Oracle Documentation "Delete backup" will be delete all backups for data recorded in the RMAN Repository.


    So which is the best way easier and faster? Will delete backup include the archive logs?


    Thanks in advance. Luis!

    Can I still use them?

    I would say it is "the wrong answer to evil. When you disable log mode archive, you can only back up the database when it is stopped and only to restore and recover the database until the last stop.

    Looking at your plan, I wonder what you are trying to accomplish first log mode archive disabling and then enabling archive mode log again. Why do you think that this is necessary and what you're trying to accomplish.

    You need not disable and enable log mode archive in order to eliminate the obsolete achivelogs.

    If you are not satisfied with the retention policy, simply change it. All backups that are outside your retention policy will be considered as obsolete and you can remove them using RMAN delete obsolete, which will remove all files as well as the appropriate data backup from the RMAN Repository.

    For example you can archivelog delete all the entries backup and then delete the backupset or remove them at the OS level, do overlap and then use delete noprompt expired archivelog all.

    The retention policy applies to backup and archivelogs. However, you can have a separate archivelog deletion policy that applies to archivelogs.

    Hi guys,.

    2 SET ORACLE_SID = Test75

    3 connection to this instance with RMAN

    4 tried to restore the SPFILE from the BKP file received.


    I make mistakes and cannot continue. I don't know if I will carry out the correct steps. Please help me telling me how I should achieve this goal.

    The first backuppiece resembles a ControlFile and the other looks like a SPFILE'

    > I get error and cannot continue

    What is the error?  (I assume that you have tried to restore the O1_MF_NNSNF_SPFILE_BU_92DVGW9H_ SPFILE. BKP

    Note that you must also SET the DBID before restoring the controlfile

  • I still do the full backup after using Data Guard?

    In our system, there is a physical database standby data protection configuration. Is it still necessary to do a full backup and an incremental backup?

    Preferred to have full backup of every day.
    May be you can perform failover of your sleep, in which case there is no availability on the primary database. So do you think that the stability of the monitoring system is the same as elementary school and can give the same performance?
    location of Eve may be too far and it's only disaster.
    Allows another case, suppose that your wait is behind that primary for 4-5 days due to some problems. At the same time your production crashed while you have the chance of data fo loose 4-5 days. Recommended to have a full backup still database primary.

    If you check the stability of database daily watch and able to check your data by opening properly and you want RMAN backup, it is fine. But it is highly recommended to have RMAN backup.

    BTW, you can have RMAN backup full standby, if you want to avoid the resources to be used on the primary

  • full backup

    Hello
    I have create this shell script for rman for Oracle version 8i for full backup (database + controlfile archivelog):
    rman nocatalog <<EOF >> $LOG 2>&1
connect target sys/password@sid
run {
allocate channel c1 type disk format '/backup_full/backup%d_DB_%u_%s_%p';
backup database;
 sql 'alter system archive log current';
backup format 'backup%d_CL_%u_%s_%p' current controlfile;
backup format 'backup%d_AR_%u_%s_%p' archivelog all delete input;
release channel c1;
    }
    Now I need rman script to Oracle 10.2.0.5 for full backup (database + controlfile archivelog).

    Is this right? Should I change?


    Thanks in advance!

    Is to correct the syntax?

    Hello

    Your script above looks perfect with the exception of '$LOG' which is not defined. But I prefer to add ORACLE_HOME and ORACLE_SID in your script and also change the format specifier "%u" "%U" while RMAN generates the uniqueness in the backup files. Here's the updated script for you.

    ORACLE_HOME=
export ORACLE_HOME
ORACLE_SID=
export ORACLE_SID
MY_PATH="/backup_rman_full/"
export MY_PATH

rman nocatalog <
