symantec netbackup disk based image via the command line

  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.

    I don't understand 1.

     

    2.  Cross mount points if you specify (for example) / in the backup selection, and wish NBU to backup root and then 'cross' over to other 'filesystems' that are spearate mountpoints. for example /var.

    3.  Configurer retention time using bpretlevel command eg. bpretlevel -r 10 5 d (set ret level 10 to 5 days)

    4.  MediaDB expiratuion date is the date the last image on the tape expires.

    VolDB expire date is not set as default, but is set is the date after which NBU will not use the tape.

    5.  Impossible question, NBU creates what you could classify as tmp files in various places (that is files that are created, and then deleted sometime later).

    There is a temp dir on windows 

    Install_path\VERITAS\NetBackup\temp 

    And on unix

    /usr/openv/tmp

    But there are other files that can be created/ deleted at variuos times, and other areas where you can delete files that will be recreated with NBU restarts, so I would say this is an unreasonable question.

     Above is not clear 

    Question 1 was below:

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

    if i allow cross mount point and in backup selection i have only /.Then it will act as ALL_LOCAL_DRIVES?

    More of less, yes.  The backup works a bit different as with all local drives the master contacts the client to work out what files systems are there, if you use / and cross mount points it doesn't.  So effectivly on unix at least you would back up the same data.

    Just seen that bpimmedia has this option
     
    bpimmedia -disk_stu storage_unit_label
     
    So it looks like that is another way to find disk based images.

    CROSS MOUNT POINT WORKS ON BOTH WINDOWS AND UNIX?

    More of less, yes.  The backup works a bit different as with all local drives the master contacts the client to work out what files systems are there, if you use / and cross mount points it doesn't.  So effectivly on unix at least you would back up the same data.

     

    Above statement is valid for win also?

     

    Can i write one mount point in backup selection and check cross mount point in my environment?

    Nikhil, when you mark a post as SOLVED, you indicate that your query has been ANSWERED.

    If you have more doubts, questions, etc about Cross Mountpoints and you cannot find the answers in NBU Admin Guide I or even by searching this forum and/or Google, then PLEASE start a NEW Discussion?

    Not sure for windows, as you have 

    c:\

    d:\

    e:\

    and so on, these are different drives, not sure if NBU considers these as mountpoints.  Mountpoints are really a Unix thing.

    1.  You could always try it with a test policy

    2.  Start a new post to ask this question

    3. Look in the manual like this

     

    Cross mount points (policy attribute)
    The Crossmountpoints attribute controls whether NetBackup crosses file system
    boundaries to back up or archive all files and directories in the selected path. For
    example, if root (/) is specified as the file path on a UNIX system, NetBackup backs
    up root (/) and all files and directories under root in the tree. This attribute is
    supported on computers running UNIX or Windows 2003 and later.
    When this attribute is disabled, only the files that are in the same file system as
    the selected file path are backed up. By disabling, you also prohibit NetBackup
    Creating policies for backups and snapshots
    Policy Attributes tab
    550
    from crossing mount points to back up root (/) without backing up all the file
    systems that are mounted on root. (For example, /usr and /home.)
    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.
     
    This is from the WIndows admin guide, it looks only talks about unix, so it looks like it is not valid for windows.
