RMAN: remove obsolete & sbt_tape backups?

Hey;

After several months of separation, I'm finally studying oracle backups. I try to get my database backups small test cleaned before trying again everywhere. I'm running into a bit of a snag, however:

RMAN > list backup;


Backup list
===============
S LV TY Device Type delay #Pieces compressed #Copies Tag key
------- -- -- - ----------- --------------- ------- ------- ---------- ---
5. A 10-AUG-09 SBT_TAPE 1 1 no TAG20090910T115704
6. A 10-AUG-09 SBT_TAPE 1 1 no TAG20090910T115730
13. A RECORD JULY 21 10 1 1 no TAG20100721T133933


I want these two to 10-sep-09 backups go away. How they got there is a mystery because it is a small box of linux on intel. Is not a tape drive and never did; but this isn't the issue.

I tried:

RMAN > delete backup tag = "TAG20090910T115730";

allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid = 139 devtype = DISK
allocated channel: ORA_DISK_2
channel ORA_DISK_2: sid = 129 devtype = DISK

but the backup is still there because it uses a disk instead of a band channel channel.

Can someone tell me how these two backups disappear?

Thanks for your tips/advice/suggestions

Allocate a fake tape channel and try again your deletion:

RMAN> allocate channel for maintenance device type sbt
        parms 'SBT_LIBRARY=oracle.disksbt, ENV=(BACKUP_DIR=/tmp)';
RMAN> delete obsolete;

    Hello Experts,

    Please English me to remove my old backups RMAN. We act in RMAN backup on a daily basis on the disc. you want to delete the previous day from the disk backup.

    Ideally if your backup is automatic, you need to add a line "delete noprompt obsolete device type disk;" at the end of backup scripts based on your retention policy clean the old not required for backups.

  • RMAN - location on the backup disk full

    Hi guys, I have problem with RMAN backup of some databases is strongly exploited during a day. We have storage problem (disk backup destination) when you do the backup of it. I would like to change retention for this database from 2 to only 1 day because these disk backupsets heading a tape every night. But before I do that, I need free space on the backup disk that is almost 100% full.

    So my question is possible to delete old backup sets and continue the backup operation? If this is the case, I could just delete backupsets of RMAN, simply delete all backups of full disk location and simply take the new backup?

    I use this script to do the full backup:

    target connection.

    Run {}
    cross-checking of backup;
    obsolete report;
    delete noprompt obsolete;
    delete expired backup noprompt.
    backup database more entered archivelog delete;
    obsolete report;
    delete noprompt obsolete;
    delete expired backup noprompt.
    cross-checking of backup;
    }

    "exit";

    I would like to delete the backup more to buy disc because this database uses disk storage space, and is to develop the database so therefor I decide to do in this way.

    Could you please give me a link or try to explain how to remove the backupsets that I have on the storage of full disk and continue with the operation to bakup? IM new in RMAN and I want to make sure that I'm doing the correct things.

    Thank you!

    According to my understandig of your question... you want to remove the last backup because you save it to tape. If it is problem, then remove the rman backup.

    RMAN > delete noprompt backup; and continue the backup for the next days

    RMAN > run {}
    backup database archivelog;
    delete noprompt obsolete;
    }

    I hope this help you :)

  • RUN 'delete noprompt obsolete' before 'backup database '.

    Hello

    11g on windows 2003, window 3 day recovery

    For almost a year now, I have after having run the script every day to save my database below. Now I begin to run out of disk space and cannot run backup commands unless I run 'delete noprompt obsolete' first.

    backup database tag = database_full_backup;
    backup ARCHIVELOG all delete them tag input = achivelog_backup;
    cross-checking of backup;
    delete the backup expired;
    delete noprompt obsolete;

    Is it a bad idea to rearange the order of commands like below?

    cross-checking of backup;
    delete the backup expired;
    delete noprompt obsolete;
    backup database tag = database_full_backup;
    backup ARCHIVELOG all delete them tag input = achivelog_backup;

    Thanks for any help

    Hello
    No problem. You have configured a window of 3 days recovery, it means you want to be able to restore/recovery sysdate - X (up to 3 X) at any time. RMAN which will always respect, you can "remove obsolete" when you want.
    Best regards

  • How can I remove application Mega backup that I installed when I thought I was the update for adobe flash download. I've got El Capitan.

    How can I remove app Mega backup of my desktop computer. He got installed when I thought I was downloading an update for adobe flash.  I closed the application them tp mpved ot trash, but he would not accept it stating still open app.

    "MegaBackup" is an application of unworthy of trust-storage cloud or perhaps real malware. I have not tried to make this distinction. To remove it, please start back up all the data (not with the MegaBackup himself, of course). Then take the steps below.

    1 Select the elements of the connection tab in the users pane and groups of system preferences. Remove all elements with a name starting in 'MegaBackup '.

    2 log off or restart the computer.

    3. slide the MegaBackup application in the Applications to the trash and empty folder.

    Note that you cannot delete any application trying to drag its icon from the LaunchPad or the Dock. You must open the Applications folder in the Finder.

    You may have installed ad-injection with MegaBackup malware. If you don't see unaccustomed pop-up in a web browser, ask for additional instructions.

  • If I saved photo on an external hard drive, now remove the laptop backup files to free up space?

    If I saved photo on an external hard drive, I can now delete backup files from the laptop for free space - my 'E' drive is full and cannot run backups more.  Also other documents that have now been removed still have backups that I need?  How will I know what backup should I keep not individually through hundreds of files?  Thank you in advance.

    Original title: can anyone help please?

    Hello

    You can take a safe backup.

    After you create your first backup, Windows backup will add new information or changed to your subsequent backups. If you save your backups on a hard drive or network, Windows backup will create a new backup, full for you automatically if necessary. If you save your backups on CDs or DVDs and could not find an existing backup disk, or if you want to create a new backup of all the files on your computer, you can create a full backup. Here's how to create a full backup:

    1. Open backup and restore by clicking the Start button, clicking Control Panel, clicking system and Maintenance, and then clicking the backup and restore.

    2. In the left pane, click on create new, full backup.

  • RMAN backup location must change and remove obsolete

    Dear Experts,

    I'm working on the following environment,

    Operating system: Windows server 2012 R2

    Oracle version: 11.2.0.1.0 release

    Type of RMAN backup: Cumulative (preferred by the direction and I can't change it in differential backup)

    My current situation,

    I set up RMAN and H: drive for purposes of backup and G: for Archivelog.

    Recently, my city was covered by the flood waters and the server works not for a week so that we delete obsolete level 0 does not work.

    Currently there is not enough space to run a level 1 and level 0, while I should change the backup location.

    My Question is,

    (1) I need to change this location of drive H: to G: drive backup backup correctly without error not enough space.

    (2) after having taken a level 1 and level 0, depending on my 1 redundancy, RMAN mechanism should delete obsolete backup disk without failure G: and H:.

    Kindly help me how to get to my need. This will help me, thanks in advance

    You can

    1. replace the DB_RECOVERY_FILE_DEST G:

    2 run backups

    3. wait for the DELETE OBSOLETE delete obsolete backups of H:

    and then

    4. change the DB_RECOVERY_FILE_DEST return h as it was more early

    In this way, you don't have to use the FORMAT or CHANNEL of CONFIGURE commands (I was referring to CONFIGURE CHANNEL, not ALLOCATE CHANNEL) to change the destination of the backup

  • Data Guard - RMAN removing archive log

    Hello

    I ' v DataGuard with physical standby.

    I do a backup only on the primaries. Both sites have ther separate backup systems.

    I ' v FRA and configured archivelog deletion with RMAN configuration:

    on primary: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;

    standby: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;

    It works fine but I think what if scenarios and I'v qestion on best practices for backup after the transition of role management. Let's say that for some reason, as i'v in switch mode sleep for a few days and the backup will be posible to watch (now primary) database. What would be the steps/reconfiguration appropriate to do?

    1 should I reconfigure RMAN?

    change of new primary to: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;

    change back to sleep again: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;

    2. make full backup

    Hello

    1. you can refer to the oracle documentation: http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmconfb.htm#CHDCFHBG

    section: "all archived Redo Log deletion policy."

    Document provides the best algorithm to analysis of work

    You can use the CONFIGURE ARCHIVELOG DELETION POLICY BACKED UP integer TIMES TO DEVICE TYPE command to allow a policy of removal of archived newspaper. This configuration specifies that archived newspapers are eligible for deletion only when the specified number of archived log backups exist on the specified device type.


    If the deletion policy is configured with the BACKED UP integer TIMES clause, then a BACKUP ARCHIVELOG , the command copy newspapers, unless integer already exist on the specified device type backups. If integer are backups of logs, then the BACKUP ARCHIVELOG command ignores the newspapers. In this way, the deletion of archived newspaper policy works as a default NOT BACKED UP integer TIMES clause on the BACKUP ARCHIVELOG command. Note that you can override the deletion policy by specifying the FORCE option on the BACKUP command.

    The deletion of archived newspaper policy has also options specific to an environment Data Guard. , then RMAN can delete logs after they have been applied to all destinations remote mandatory. If you specify SHIPPED TO STANDBY , for example, then RMAN can remove log files when they were transferred to all destinations of mandatory relief.

    2. the paper provides good information, just to check and decide easily based on the functionality of the database role you can configure.

    It will be useful.
