    I agree with Nicolai - quite normal...

    How long does it take to run 'ls -lR' against this filesystem?
    NBU (bpbkar) needs to do the same in addition to reading each file in order to backup it up.

    The alternative is to see if FlashBackup is an option.

    Or else multi-streaming as per Nicolai's suggestion:

    NEW_STREAM
    /big-volume1/folder1
    /big-volume1/folder2
    NEW_STREAM
    /big-volume1/folder3
    /big-volume1/folder4
    NEW_STREAM
    /big-volume1/folder5
    ...etc

hardware is old but strong)).. E2900 sun server with 65GB RAM and 8 CPU..populated 3 CPU MEM board

So why solaris 9? Because of application requirement on it.

My friends which are they tried (3 years ago ) to install netbackup 7 version was unsuccessful. So they told me this system is compatible only with 6 version.
