  1. symantec netbackup disk based image via the command line?

  2. When would I, or would I not, use cross mount points?

  3. symantec netbackup configure retention from command line ?

  4.  What is the difference between the expiration date for a volume in NetBackup's media catalog and Media Manager's volume database?

  5. In which location(path) the temp files located in Netbackup for Windows/Unix?

    /var is a separate mount point under /

    If you do not allow cross mount points, it will not backup /var.  If you allow cross mount points, it will.

     How do you find a disk based image via the command line and then delete it?

    Look in the reports, some of them refer to disk images - one way

    bpimagelist - then search for the disk based images in the FRAG lines - another way

    Look directly in the disk STU at the actual backup images, the names of the files contain the backupid.

    Use bpexpdate -backupid <backupid> to expire them.

    Do not use theCrossmountpoints attribute in policies on UNIX systems where
    you use the ALL_LOCAL_DRIVES directive in the backup selection list.
     
    Why this is so?

    Because ALL_LOCAL_DRIVES will backup all the different mountpoints.

    If you select cross all mount points it would backup up things twice.

    Consider this simple example.

    The server has just two filesystem

    / 

    /var  (this is a separate mountpoint)

     

    If I select cross all mountpoints and tell it to backup up /

    NBU will start to backup /, when it gets to /var, it is allowed to cross into it and back it up - as you understand.

    If you the use all local drives and cross mount points

    First, NBU works out what the separate mount points are (this is a difference when using all local drives)

    It works out it has to backup / and /var separately

    NBU will backup / as before, when it gets to /var, which is listed under / -  because cross mount points is allowed, it will backup /var, but, it is backuping up /var as part of /

    Once it finishes, it will backup the next filesystem in the list, which is /var

    So, /var will have been backed up twice

    Then in that case?

    You have these choices: 1) Backup / with 'cross mount points' 2) Backup ALL_LOCAL_DRIVES without 'cross mount points' All of this is explained in Admin Guide I. PLEASE start a new discussion if you still have doubts. You have marked this thread as SOLVED. This means your questions were answered, right?

    In some cases, consider creating separate policies for the backups that cross mount
    points and those that do not. For example, in one policy, disable Cross mount
    points and include root (/) in the backup selection list. As a result, only the root
    file system is backed up, and not the file systems that are mounted on it. In another
    policy, enable Cross mount points and include root (/) in the backup selection
    list. As a result, all the data on the client is backed up.
    Note: NetBackup specifically excludes mapped directories even if FollowNFS and
    Cross mount points are enabled. To back up mapped directories, include the
    directories in the file list.

    It would only back up / and not backup /var, as /var is a separate mountpoint.
