Compressing rman backup

Hi all,
My database is growing up adn becomes very big, i have a problem of the backup because when i take full backup it gives error of disk space. I want to reduce the size of my backup and i know the existance of compressing rman backup.
My question is how to set rman compressed backup and is compress option working for incremental backup or not. I want this because i'm taking full backup once a week ansd incremental backup every monday till saturday.
Thanks for the help
Ratsarevo.

Hi,
Thanks all for your replies, No i'm reassured for my backup type.
Here is my backup configuration:
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/data1/rman_backup/%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO COMPRESSED BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT '/data1/rman_backup/%d_%T_%U';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT '/data2/rman_backup/%d_%T_%U';
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/data1/rman_backup/snapcf_abdb.f';
Is it good for compressed backup ?
Thanks

  • How to make an encrypted compressed RMAN backup and recovery

    Hallo!I am trying to make an RMAN backup that is compressed (definitely use compressed backup set in OEM).
    But my emphasis is to make the backup encrypted with a key (hoping to use Public Key Infrastructure )such that the database data can be sent via the network and the recepient can use a decryption key to decrypt the data.
    The recepient must also use a password to access the encrypted file for decryption.
    Is it possible to do this?If so please give the steps.
    Thanks.

    You can encrypt the backupset with RMAN Encrypted Backups, however Oracle Advanced Security Option (additional cost) is required.

  • Rman backup size for Dr db is very much higher than that of primary db

    Hi All,
    My production database on Oracle 10.2.0.4 had a physical size of 897 Gb and logical size of around 800 Gb.
    Old tables were truncated from the database and its logical size got reduced to 230 Gb.
    Backup size is now 55Gb which used to be of 130 Gb before truncation.
    Now this database has a DR configured. Backup of this DR database is daily taken which is used to refresh test environments.
    But the backup size for DR database has not decreased. The restoration time while refreshing test environments is also same as before.
    We had predicted that the backup size for DR database will also decrease and hence reducing the restoration time.
    We take compressed RMAN backup.
    What is the concept behind this?

    When you duplicate a database it will restore all the datafiles from the RMAN backup. You will find the physical space of your source database. Remove the fragmented space using object movement. Then shrink the tablespaces and take fresh RMAN backup and restore.

  • Related to Unused compression in RMAN backup for 10.2.0.4 database

    Hi
    I recently read through one of the document related to Unused compression in RMAN backup for 10.2.0.4 database. According to this
    Unused Block Compression is done, if all of the following conditions apply:
    + The COMPATIBLE initialization parameter is set to 10.2
    + There are currently no guaranteed restore points defined for the database
    + The datafile is locally managed
    + The datafile is being backed up to a backup set as part of a full backup or a level 0 incremental backup
    + The backup set is being created on disk.
    I have two queries
    1) What is meant by "uaranteed restore points defined for the database"
    2) If backup is being directly taken to tape, this feature would not be used
    Rgds
    Harvinder

    1. Normal and Garanteed Restore Points
    2. No

  • RMAN backup compression and tape hardware compression

    Hello,
    Should tape backup compression be ON and RMAN compression OFF? What is the correct Oracle answer?
    Common knowledge says that if both hardware and software compression were allowed to be enabled at the same time the resulting file in some cases may actually be bigger than the original file. Hardware data compression is done by specialized chips and faster than software compression and increases the tape performance.
    I was reading somewhere some time ago that tape hardware will actually not attempt to compress data if the the data being processed cannot be compressed any further. But even if this is a hoax, wouldn't rman compression, at the cost of CPU, save I/O bandwidth?
    Thanks.

    I just located Oracle document ID 1018242.1, which outlines:
    Use either hardware or software compression, but NOT both. Using both will actually increase the size of the resulting file. The rule of thumb is: compression + compression = no_compression.
    Sounds kind a logic.I was actually going to post the same sentence but you did find it on your own :) . Another thing which is worth to mention that from 11.2, the RMAN backup compression is licensed with 4 options, High, Medium and Low . These all three options requires you to have Advanced Compression License to buy. There is another 4th option, Default which is free from license and the compression ratio of that lies in between of Medium and Low.

  • How to find the compression algorithm  used on a RMAN Backup

    I have list of backups taken using different compression alogrithms. I need to query and find out the compression algorithm used on existing RMAN Backup. I tried querying the view V$RMAN_BACKUP_JOB_DETAILS.

    I am not able to restore spfile from rman backup ;;;

    Hi,
    I would like to know few things
    1. How are you setting the db_name ? you can set db_id at RMAN, how are you setting the db_name ?
    2. Do you have any default init file at default location ? if yes, is the db_name parameter set correctly in that file ?
    Since spfile is yet to be restored, you must set the db_name parameter correctly before you start spfile restore.This can be done with init file at default location which can even contain just one paremeter i.e db_name.

    Hi,
    never tried it, but I know that the shared folders in vbox don't work like normal filesystems.
    I would rather setup an NFS server on the host and mount an NFS share in the guest.

  • Rman backup - how to preserve the file names exactly when backing up?

    Hi,
    I have been using RMAN for backup and I want to change things so that it is
    easier to go back to the old tried-and-true method of recovery by recreating
    a control file manually via the trace file, which lists the files out individually.
    The first change - to change from compression to copy.. is fine.
    But even then, rman names the files some weird name.
    I am not trying this- using the disk format command is supposed to work..
    rman nocatalog << EOF
    connect target;
    allocate channel for maintenance type disk parallelism 1 \
    format '/agile/ora_flash_recovery_area/PECHA/backupset/backup/%U';
    backup as copy database;
    release channel;
    but it still is using wierd (auto-generated) names for the data files as it backs up.
    Has anyone else got this working? Thanks Marvin.

    Ok here is why I would like exact filenames..
    1) to speed the time of recovery. I am much more familiar with traditional recovery methods than RMAN, and while I myself installed and suggested RMAN for backups, our other (11i) database does not use RMAN and so I am more familiar with traditional recovery. So to be able to recover quickly I want to have these files as close as possible to the original names so that I can use my standard script (from a trace file) to recreate the control fiile. If I can get RMAN to spit out the filies with original names but keep RMAN for making the backup, I may ditch the rman bacjup script in chron and write a traditional hot backup script which copies the files the old fashioned way.
    2) to reduce cloning time. The RMAN duplicate command is not as good as I thought. I was actually easier for me to restore RMAN backups first to a box that has all the same paths, and THEN shutdown (cold) these files and copy them cold to another server, and restore from there. Agaiin if I can get the original file names, I could choose to do recovery either way (RMAN or traditional) in a real emergency instead of being forced to use rman.
    3) to be able to switch to a backup file in the FRA without having to rename it. Seems logical if it is already named correctly.
    thanks ! Marvi

  • RMAN backup and restore for Disaster Recovery

    Hi Guys,
    I am very new to Oracle and have a question about RMAN backup and restore feature. I am simulating a disaster recovery scenario by having two VMs running oracle 11g, say hosta and hostb, hosta is sort of production db and the other a disaster recovery db (one that will be made primary when disaster occurs). My goal is to backup production db using RMAN and restore it on the other machine. For some reason when I restore the db on hostb, the command restores the previous backup but not the most recent one e.g. I took a backup yesterday (09/20) and applied it to the hostb that worked fine, but when I try to apply a fresh backup from today (09/21) it always picks up the old backup. Here's a dump of the screen:
    Starting restore at 21-SEP-11

    Thanks guys, I really appreciate all your help here. I redid everything all over again to get all the information you guys wanted. Since I noticed that more eyes are looking into this I am going to reiterate my steps one more time followed by specific answers to questions. My first backup on Host B is located under ..../restore_db/backupset whereas the subsequent one is under .../restore_db/backupset/backupset2.
    I take backup on Host A using:
    rman target /
    backup as compressed backupset database plus archivelog;
    backup spfile;
    quit;
    I restore the backup on Host B using:
    set dbid=13732232063;
    startup force nomount;
    restore spfile to '/oracle/app/dev/product/11.2.0/dbhome_1/dbs/spfileforums.ora' from '/export/home/dev/restore_db/backupset/o1_mf_nnsnf_TAG20110928T171830_787gbpxh_.bkp'
    shutdown immediate;
    startup force nomount;
    restore controlfile from '/export/home/dev/restore_db/backupset/o1_mf_ncsnf_TAG20110928T171638_787gbkxn_.bkp'
    quit;
    /* restart rman here */
    alter database mount;
    catalog start with '/export/home/dev/restore_db/backupset' noprompt;
    restore database;
    recover database;
    alter database open resetlogs;
    quit;
    I take another backup on Host A using (notice no spfile backup this time):
    backup as compressed backupset database plus archivelog;
    quit;
    I restore the database on Host B using:
    alter database mount;
    catalog start with '/export/home/dev/restore_db/backupset/backupset2' noprompt;
    recover database;
    alter database open;
    quit;
    Output of List Backup of database (I have done this after I recovered the second time, also note that it is referring to backupset2 which is were my second backup is stored)

  • Rman backup strategy

    hi,
    just wanted to hear some thoughts from some pros..
    platform: oracle 9i on windows
    i switch from user-managed backups to rman recently. My full nightly backups are abt 20GB in size on completion.
    we backup to tape, but i want to keep some disk backups for faster recovery.
    i do not have disk space to keep more than 3 backups at any time. Cleanup will be regular and tedious. If i use a utility like gzip after, i can get it down to abt 4-5 GB and thus keep alot of backups on disk.
    Does it make sense to compress all backups "older than the latest", and reduce the size so i can keep abt a week on disk?

  • Oracle 9i RMAN backup filling up all disk and failing at the very end

    Hello to all and thank you in advance for any input from any of you.
    I am new in oracle and the only one in my company with a little bit of oracle knowledge, which is not a whole lot.
    I inherited a few servers (Linux and Windows based). We mostly run all our production environment on a Linux box hosting oracle 10g release 10.2.0.1 but we had a legacy application server that still runs on 9i release 9.2.0.1.0. This server is a windows 2003 box, the previous DBA or someone else with admin rights to this machine compressed the whole drive where oracle resides, when I started summarying the oracle assets, I saw this server with no backups scheduled and a compressed disk with very limited space after this compression, only 13 GB left, the database if uncompressed would definitively filled up all the disk. The machine is in used and cannot be taken down for more than a couple of hours. We tried adding another disk but the machine only accept it as a hot spare. The database is in archive mode, when I tried to run a RMAN backup, it start filling up the database drive until it's empty and it crashes the whole machine, it seems like the buffer is growing and growing until it fills up the whole drive. The only way to get the server up and running again is to reboot the machine since the server is more than 6 years old we are not please with this action because we are afraid the machine would go south in one of those reboots.
    Has anyone heard of similar issues when running RMAN on a compressed drive? Can the compressed disk have any involvement in this kind of odd behaviour? I tried running the backup in debug mode and creating a log in a different disk (the one where the backup is going to) and still the same issue. Again any help is much appreciate,
    Sincerely,
    Alex

    Sybrand,
    Thank you for your fast response, I am going to use your previous post to answer one by one your question,
    1 The Oracle binaries --- on a compressed drive > Yes
    2 The Oracle database control files redo log files and datafiles on that same compressed drive? > Yes
    3 The archived redo log ditto? > Yes
    I know for a fact (as I have been using that in 9i) you can create a RMAN backup on a compressed drive, and you can have your archived redo go to a compressed drive. No problemo! > Excellent good news!!!
    But I would never touch the data files. Please note backup sets are multiplexed files consisting of multiple datafiles, so RMAN would need to do some calculations to decompress several blocks at the same time and to calculate a new block and compress it.
    Do you have enough space to:
    a) (preferred) to make datafile copies instead of a backup >
    Not in the drive that hosts the oracle instance but yes on an external usb drive (1TB) I attached to use as a backup repository, maybe this is why I am having these issues. I only have 13 GB left on that drive where the oracle instance resides (actually as I explained in a previous reply to Mark, the server only has 3 slots for disks, two of them as configured as RAID 1 and the other is a hot spare because the RAID configuration manager cannot can only added as hot-spare. The raided disk are partitioned in two, one small partition is for the OS and the other is for the oracle instance). When you said make a copy of the datafiles, I assumed you are talking about doing manual backups, and copying the database after using using "alter tablespace tablespace_name begin backup; then copy the file; alter tablespace tablespace_name end backup;
    b) use filesperset=1 on the backup command line, so the multiplexing (and associated calculations) stop. I have not tried the option of fileperset yet but I can tryi it and see if that helps.
    Can you post the last few lines of the RMAN log where RMAN bombs out? Note: the last few lines. Not all of it, or you must send some paracetamol in conjunction! >
    When I ran the debug option, I stopped the backup at less than 20% because I didn't want to reboot the system in the middle of the production time, the backup consumed at least 3 GB during the time was running. The times I ran the RMAN backup I didn't used the debug option so I don't have a log long enough to send unless you want the last few lines of what I have.
    Thanks again for your input,
    Sincerely,
    Alex

  • RMAN backups need info about available options

    Hi All
    In our new 10.2.0.3 RAC environment on windows 2003 os we have our database configured on ASM and oracle home placed on OCFS. As it is a prod environment, we do not have the comfort to shutdown the cold copy of the database and so we're running the daily rman full db backup .. however, in case of an event where the datafiles need a restore.. I am not sure if the rman backup i take will be sufficient.. I issue the below command to take the full database backup and I get a compressed back up set..
    RMAN> backup up device type disk format 'd:\database\%U' database;
    I do have the FRA configured on ASM DG but i see that this DG is almost free. could any please advice what are the options available for me to take the entire database backup (including files) which can help me restore the datafiles if necessary.. my database is about 70GB in size but is very critical for organisations functioning..
    thanks!
    Sarat.

    Thanks for the quick reply steve and werner...
    Because we are doing a daily Full database backup (compressed) I did not include the archive logs to be backed up. In our environment, we keep moving arc logs to another archive location regularly. and once back up is complete and successful we clean up all archives using another job as we no longer would need them in case if we need to restore from the RMAN backup.. and as we retain all archives between one rman bkp and the next one.. we are also not backing up these along with the database.. Is this dangerous? I thought we will always have one database copy (compressed) available on disk and can help us restore from it if required.. But my major concern is what if a datafile is accidentally deleted/ disk fails on ASM. In this case.. the RMAN backup will not be sufficient because if cannot create the physical structure.. in such a case, will configuring the FRA it self be sufficient? Do I need to perform any additional steps to ensure the physical structure can also be restored? Please advice..
    rman is configured to backup control file and sp file and my exact script looks like below .. and we run it every day
    crosscheck backup;
    crosscheck backup of controlfile;
    delete force noprompt obsolete;
    delete backup;
    backup device type disk format 'D:\oracle\DBBackUp\%U' database;
    exit;
