/opt/openv/netbackp/db/images/dag is 30GB big

hello

can i delete folders under /opt/openv/netbackp/db/images/dag? does that affect the dag/GRT policy?
if the answer is we can clear the folders, can I clear the folder using the rm command in solaris or I have to expire images then the folder will be freed up?

thanks,

    NO!!! Please don't! 

    These are catalog entries for your DAG backup. These catalog entries enables you to perform restores. Files in this folder will automatically be deleted when backups expire naturally.

    Catalog size is directly related to the number of files held in backups. 
    The best way to manage catalog size is to reduce the number of copies of  a backup you are keeping.  Review the backup policies and reduce the retention and frequency of full backups.  

    Are you perhaps doing full backups every day with long retention periods?

    Before you start expiring backups, have another look at backup policies and check frequency of full backups and retention levels.

    You may also want to consider disabling the cataloging for duplications - see this topic in NBU for Exchange manual:

    Marianne,

    what about the log files in /usr/openv/netbackup/logs?

    some of the directories there is really big 10GB approximately; the bpemm log directory, can I clear the content of log files or they are used for archiving?

    hi, there is no bpemm, there is nbemm logs. These can be cleared down.

    for unified logs (nbemm = 111 , nbjm = 117,  nbrb 118, nbpem = 116 etc) use this command:

    vxlogmgr --del -p 51216 -o 111 -e <enddate>    # deletes emm logs if you specify a enddate

    The old legacy logs can simply be deleted manually. If you don't want them to log at all remove the directory names for the legacy logs.

    Please move the solution back to the answer that you originally gave the solution to, it is not fair on Marianne if you deselet her answer - she gave the correct answer first.

    Extra questions need to go in a new post - then revaroo can copy his anwer is nad you can mark this as the solution.

    Multiple questions in the same post are not fair, as only one person can have the solution, but multiple people may have given the solutions to the vasrious questions.

    Thanks,

    Martin
