NetBackup catalog verify gets "no images found" message.

Created: 15 Jan 2013 • Updated: 18 Jan 2013 | 7 comments
This issue has been solved. See solution.

Due to budget constraints, I am not able to get any new tapes for backup to our Quantum PX720 tape library, so I am looking at expiring and re-using older tapes. I am using the NetBackup admin console in the catalog section to verify the contents of tape media in the current list. Some media is showing the images that have been backed up to tape, but others show the following:

"INF - Status = found no images or media matching the selection criteria."

Initially, it looked like I was only getting this message for tapes that were not currently in the tape library, but now I am seeing output for valid images even on tapes that have been vaulted for offsite storage. Does this message mean that NetBackup has no image for the tape? Or just that the current configuration has no record of that data? If I imported that tape media, could I expect to see the images on the tape?

I am trying to determine which tapes can be reused for backups, but without any idea of what is actually on the tapes, this makes the decision process more difficult.

Maybe all images on these tapes have already expired?

If retention levels are in line with business requirements, there should be no need to worry about 'what is on the tapes'. 

If you go to Media section and sort by Assign Time. All media without date/time in this field are available and can be overwritten.

To see when tapes with valid images will expire, use Media Summary report (in Verbose mode).

Thanks for the fast response. I am working with management on retention levels so the contents of some tapes will not matter. I am looking at tapes with an empty "Time Assigned" filed, but what about the media that has a "Time Assigned" field filled in, but still gives me the "No images found" message?

Try 'Images on Media' in the Reports section of the GUI.

Another thought - if a tape got frozen for some reason, the images will expire normally, but the tape will never be deassigned.

Please show us output of this command for one of these tapes:

nbemmcmd -listmedia -mediaid <media-id>

Here is one of the tapes with the "Time Assigned" field filled in, but the catalog verify produces the error message:

I see from the Media Summary report (verbose mode) that some tapes will be expiring within the next month, which is definitely help. But if we can re-use tapes as old as this one, it will give us upwards of 400+ tapes!

The data should be inteact on this tape as it is set to infinity, and it was never used again after 2006.While doing the catalog what date range you have slected. Make sure you select the catalog time range while searching as 01/03/2006 till 10/03/2006 to get result. Let us know if it reports the same error after changing the date range.

Edit*: Also it is better to have your retention as per the SLA and not infinity as it would be very hard to get the data and delete them and therer is always chance for error. Better to retain the data as needed like 1 month,1 year, 7 year and once the retention is over it will automatically move the tape in scratch pool. I hope you undestand what i mean.

There are 66 valid, unexpired images on this tape.
As per my previous post, you can use Images on Media report to see image info.
Please note that the report as well as Verify will simply give header info such as client name, policy type, backup and expirations dates, image size, etc. No file list info.

Thank you for your comments, they have been very helpful and I now have a better understanding on how to manage my tape media.
