Why does OmniBack append the data to this tape and does not overwrite (reuse) it.

Before a backup starts I check in the Media Manager/ Media Info for any objects that are protected. There are none. The backup is started at night. The next day I check for the objects again. I find protected objects on the tape which are of the backup. But the other old objects are still on tape. OmniBack appended the data. After a few weeks the tape is full. While OmniBack is allowed to overwrite the tape because there are no protected objects on it.
Recycle does help. But in case the wrong tape in loaded this will remove protected objects as well. That is what I do not want. Isn't it.
BTW I do not want to do this on a daily basis. OmniBack should be clever enough to do that in a controlled way.

The only thing i would please you to do is to look for the actual patches:
Sorry for no more detailed help.

" omnimm -list_scratch_media
to get a list of "expired" tapes. I always select form the top of the list (oldest tapes)
and use them for my next backup.
In the media manager, I check the Info regarding the tape, and I do not get any appends to an expired tape. I have done it this way since 2.55. Are you certain you have the protection set correctly?? maybe you should change to 6 days, that way it would be expired on the 7th.

Media policy, Have you tried changing the policy to
Non Appendable ??

I do want to append on this tape because during the night we make first some backups for Oracle with RMAN then we make a backup of the filesystem.
If I ask for a list_for_scratch_media none is listed.
Perhaps I come back to the issue that OmniBack does not eject the tape because we want to do more backups during the night as I said before, so OmniBack does not know about this because we have to do it by hand. Is there a way to lett Omniback eject the tape at the end off all sessions or inform Omniback about the ejected tape so that the OmniBack database is consistend with that.

You may want to recycle the media before you back up.
In the monitor interface, check to see if you have permanent catalog protection.
to solve this, set catalog=data protection in your backup options.

1. If your pool is defined as appendable, even though it is expired omniback will still append the data at the end of previous backup. This will ensure the flexibilty to restore even though the tape is not protected anymore. The objects are still in the database as long as the data is not overwritten.
If your pool is non-appendable, then it will be overwritten at the end of the cycle. You can test this scenario.
2. you can go to advanced options in your logical drive configuration and check the eject option, so that omniback will take care of the eject operation once the backup is done.
Hope this helps.
