Image cleanup on dedupe volume is not straight forward - if any other image still rely on a previous backup, then the data will not be removed from disk when expired.

You may want to read through these sections in NBU Dedupe Guide and then double-check all the relevant processes in your environment:

Hi Marianne.

I tried already all these steps except the -notimmediate option.

Seems my issue is caused by disabled SLP. Months ago I had to disable the replication to onter storage.

According to info from Mark_Solution, if an image is not duplicated by SLP it is set to infinite retention intil replicated.

I cant allow to replicate any of the images due space issue on the other storage. So I have to somehow let the not replicated images to expire.

    Hi

    Look at the "force_not_complete" option to bpexpdate - this will expire images that are still in SLP processing.

    Cheers

      Hi David.

      Thank you very much for your comment.

      Actually I"m running the bpexpdate with -force_not_complete command and I see in the "nbauditreport", that plenty of old images (based on the image ID number) got expiration date change.

      Do you know when I will see any result of this on the disk pool? Or how to force to free the space on the storage imeediatelly? I need to get the free space as soon as possible, as right now no backups running at all because the free space on the storage is below 3%.

      thanks

      Marian

    I see that you have found an old post : https://vox.veritas.com/t5/NetBackup/Dedupe-disk-is-full/m-p/875046

    Yes, original SLP backup copies get an expiration date of INFINITY until all secondary actions have completed successfully (e.g. duplication and/or replication). This has always been the case and documented in the Storage Lifecycle chapter in Admin Guide I.

    It is extremely important that you work with a knowlegeable Veritas partner that can assist with correct dedupe sizing to ensure that your capacity meets your company's retention requirements. Hopefully there are plans in place to increase capacity on your 'other storage' ? 

    You can expire images as per davidmoline 's post, or cancel the outstanding SLPs that should've expired by now.
