Thread: Added "tape_splitsize 2 Gb" but see a lot of really small 10mb files

  1. #1

    Default Added "tape_splitsize 2 Gb" but see a lot of really small 10mb files

    Strange thing happening.
    I've added "tape_splitsize 20 Gb" parameter into amanda.conf

    define dumptype comp-user-span {
    global
    tape_splitsize 20 Gb
    comment "Tape-spanning non-root partitions on reasonably fast machines"
    compress client fast
    priority medium
    }

    Disklist definition:
    gate.sim.ionidea.com /var/spool/imap {
    comp-user-span
    auth "bsdtcp"
    } 1


    And using that to backup really big stuff about 300Gb
    (I have no hold disk so nackups going directly to virtual tapes)

    But once I've started amdump and estimate passed I am seeing that thousands of files start creating in amandatapes/slots/current directory.
    I am still waiting for complete but that is really strange.
    Why it dosn't creates 20Gb parts???

    Default

    When doing dump direct tape, you must set a split_diskbuffer to a path where amanda can store a file with the size of the tape_splitsize

    Default

    Thanks for the replay.
    Already got things rolling after reading lines below tape_splitsize in config

    Anyway thanks.
