Dear Experts,
Kindly please advise why the NBU provided tar does not report the exact file size
when it's over 1GB.
For example, we have some files in "/mnt".
root@e420 # ls -al /mnt
total 6428710
drwxr-xr-x 2 root root 512 Sep 10 21:12 .
drwxr-xr-x 37 root root 1024 Aug 30 09:17 ..
-r-xr-xr-x 1 root root 68635077 Sep 10 21:12 NB-Java.tar.Z
-r--r--r-- 1 root root 102 Sep 10 21:06 hosts

As we could see from the above screen capture, tar shows only
1GB of size instead of 3GB for "myfile1.3g".
However, the file size is correct after extracting to disks.
root@e420 # mkdir /mnt/tmp
root@e420 # cd /mnt/tmp
root@e420 # /usr/openv/netbackup/bin/tar -x -v -p -f /tmp/mytape1
Blocksize = 128 records

Removing leading / from absolute path names in the archive.

Is this a bug or some kind of limitation within the NBU tar?
Is there anyway that we could do to avoid or fix such a problem?
Btw, we're using NBU 6.0 MP5.
Kindly please advise.
Many Thanks!
Best Regards,
Richard
