Decommission Datadomain Media Server

Hello All,

 

I wish to decomission a media server which writes into DD4500, In same time I want its iages to stay there.

I alreayd marked the images as infitiy expiring images.

Will nbdecommission clear the images?

    Ok so you can run nbdecommision - I think - all backup images written by this media server (to that storage server) will be logically assigned to the other new_media server... I was thinking you have 1:1 ratio media -> storage server, but this is not the case...

    nbdecommission -oldserver hostname [-list_ref | -newserver hostname [-bulk_media_move] [-file op_dump_file]]

    Hello

    Most likely nbdecommission will expire all images on this media server.... If you want to preserve these backup why you are willing to decom that box? Why don't you deactivate this media?

    If you want to get rid of this box I would disconnect it from network, run nbdecommission - so all backup images from catalog will be gone, but these will be still physically available on this box - as NBU will not be able to delete it from device - not on network any longer.... Later on you can import these back - I think.... long running process

    or you can try the bpexpdate -nodelete - command:
    "Deletes the backup from the image catalog but does not delete it from the disk storage. Use this option when you unimport a disk group from one master server and import the disk group to a different master server."


    Can you share why you need to decom it?

      Thanks Quebek,

       

      The sotrage server is used for multiple media servers for management purpose.

      Once i decomission a media server without using nbdecommission command, the storage server will go down in next backup on any other media server.

      I run bpexpdate, is there an advice to keep the images showing in catalog? can I move their ownerhsip to another server?
