    I am new at a company that has a Unix server and they have no documentation
    or anyhting. I am a average Unix user and I am trying to figure out a few
    things.

    They have a script I assume that runs a backup tape every night of just one
    area of the data files. No documentation or anything and no one knows what
    or how its being done. So no idea if they are using tar or dump. I am
    assuming their either are using a tar or dump command / script.

    I have been reading the MAN pages for the system to try to figure out how
    to format the line to do say a tar backup. I also need to know how to do
    a restore from a tar file assuming they are using tar. Or if they are
    using dump as I understand you can use a restore or rrestore if dump was
    used?

    If anyone is out there using some nice tar or dump commands or scripts I
    would love to study them and modify them for my use. Also restore scripts.
    I want to make a tar and dump script to back up the entire system and not
    just the data files. I assuem its root that is everything to do a full
    disaster restore from.

    I have a few examples and let me know if I am putting together the right
    command lines.

    The system is using
    Compaq Tru64 UNIX V5.1 (Rev. 732) (bisalpha) (pts/4)

    Below is an example from the man pages and then below it are some of my
    thoughts of what I need to type to back up all the files in my examples on
    the system

    EXAMPLES

      1.. To create a tar archive to device /dev/ntape/tape0, enter:
    tar cvfb /dev/ntape/tape0 20 -e ./foo -C /usr/glenn . \

    -e ./bar -e ./logs/logfile -C /usr/gaston .

    The preceding command line specifies a blocking factor of 20. The

    resulting archive contains all files and directories in /usr/glenn

    except for file ./foo and all files and directories in /usr/gaston

    except for files ./foor, ./bar, and ./logs/logfile.

    now my examples and I have not yet tried this because its a live system and
    there is no "test" system to try this on.

    *************************************************************

    tar cvfb /dev/ntape/tape0 20 -C /usr/glenn . -C /usr/gaston .

    should back up all files and subdirectories of /usr/glenn and /usr/gaston to
    tape ??????

    tar cvfb /dev/ntape/tape0 20 -C /u1/Luminx/live .

    should back up all files and subdirectories in /u1/Luminx/live directory ???

    tar cvfb /dev/ntape/tape0 20 -C /u1/Luminx .

    should back up all files and sub directories in /u1/Luminx ????

    tar cvfb /dev/ntape/tape0 20 /u1/Luminx/test/data/hp.txt .

    should back up the hp.txt file ????

    tar cvfb /dev/ntape/tape0 20 -C /root .

    will this back up all of the root and all directories and sub directories
    and files as in a total hard drive / system back up?

    ************************************************************

    tar cvfb /dev/ntape/tape0 20 /u1/Luminx/test/data/hp.txt .

    should back up the hp.txt file ???? in this example what would eb the
    command to restore this file from tape back to its origional location?

    The server has the tape drive in it and its tape0 or device tape0, I have
    confirmed that.

    I am going to try to see if the company that set up and supports the
    application software on this is willing to help me, with out a cost.

    My main assignment is to simply test the tapes and figure out how to restore
    the date from the tapes back to the system and make documentation and or
    restore script to do so.

    to restore to the origional file locations or to redirect them to another
    directory.

    Also on this flavor of Unix, where or where most likely would one make and
    put the automated backup script and since it automatically backs up every
    night, what file, config file, process or task would be starting and
    running the backup if anyone can guess at that?

    I am welcome to ideas and examples of scripts or command line commands to do
    backup / tar / bump and restores.

    The most critical directory is the /u1/Luminx/live/data/ directory

    but the entire application and its data sits in /u1/Luminx/

    I am working on figuring out the method used to back up so then I can write
    a script or command line command to do the restores. I have not yet located
    the current backup script or command that the system is running each night.

    Sorry I do not have more specific info. Any and all ideas, scripts,
    examples would be appreciated.

    Sincerely,

    Chad
