backup database keep forever logs

If you want to keep some backups forever, you maybe tried

RMAN> backup database keep forever logs;

Starting backup at 13.04.2007 13:58:04
...
backup will never be obsolete
archived logs required to recover from this backup 
will expire when this backup expires
...
Finished backup at 13.04.2007 13:58:23

but the problem is that the archivelogs to recover this backup at any time after the backup will NEVER be obsolete.

You could well try the NOLOGS option, but this requires you to take the database in the MOUNT state.

RMAN> backup database keep forever nologs;

Starting backup at 13.04.2007 14:06:36
...
backup will never be obsolete
archived logs required to recover from this backup 
will not be kept
...
Finished backup at 13.04.2007 14:07:25

This is fine if you can stop your database. But you probably wants online backup. What’s next?

Ok, here is the way to go. You do your online backup, then you mark what you want to keep !

First I backup the old archivelogs, because I do not need to keep those yet.

RMAN> backup archivelog all;

Starting backup at 13.04.2007 14:10:00
...
Finished backup at 13.04.2007 14:10:08

Now I do a backup plus archivelog (with a tag for simplicity)

RMAN> backup database tag backuplsc 
plus archivelog tag backuplsc;

Starting backup at 13.04.2007 14:10:42
...
Finished backup at 13.04.2007 14:11:00

Now I can mark my backup as keep

RMAN> change backup tag backuplsc keep forever;

...
keep attributes for the backup are changed
backup will never be obsolete
backup set key=405 RECID=116 STAMP=619798257
keep attributes for the backup are changed
backup will never be obsolete
backup set key=406 RECID=117 STAMP=619798260

Now if I do a delete obsolete, it will never delete my backup.

RMAN> backup database plus archivelog
Starting backup at 13.04.2007 14:16:46
...
Finished backup at 13.04.2007 14:17:10

RMAN> delete noprompt obsolete;

RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1
...
Deleting the following obsolete backups and copies:
...
Deleted 7 objects

RMAN> list backup summary;

  1. This doesn’t appear to work; RMAN won’t mark a copy that includes archive logs KEEP.

  2. I’ve tried this in 10.2.0.3.0. It produces the following error: –

    This is a real pain, as I know that the backup set contains enough redo to make for a consistent restore which will give me my month end position.

  3. this is strange, either I made a copy paste error or there is something magic in the site where I tried, but it seems it works with NOLOGS.

    Ok, here I try again

    so the KEEP FOREVER NOLOGS seems to work with backup of archivelogs

  4. How do you restore that backup once you’ve taken other backups sometime later?

  5. something like

    restore database until sequence 14 thread 1
    recover database until sequence 14 thread 1

    where 13 is your highest saved redo log.

    should work

  6. Another quick question as I can’t find the answer. Anyway to change the actual tag name of the backup? I.E. change TAG20070613T000231 to something like BKUP_06132007_KEEP_30?

  7. No, I meant for a backup that is already completed. Backups run nightly, and sometimes the next day, the proj mgr wants to keep the previous nights backup and rename it.

  8. Starting backup at 13.04.2007 13:58:04
    How do you get RMAN to include the time ? (like you have)
    I only get the date in “Starting backup at 13.04.2007″ !…

    Thank you,

  9. There must be something magical at the site you did this, because it most definitely does not work for me on 10.2.0.3 either:

    My brief trip to the Backup and Recovery Advanced User’s Guide seems to indicate that the only way to accomplish this is from the consistent mount state: Keeping a Long-Term Backup: Example

  10. @Philip,

    I am fairly certain you need to be using a recovery catalog to use KEEP FOREVER. I’ve read it in Oracle documentation, but cannot find it at the moment.

  11. Hi

    I hope somebody will visit this page again.

    Oracle 10.2.0.4, standard edition. It seems it is not possible to keep backupsets that contain archived logs?
