NetBackup freezes one of our brand new dlt tapes because of media errors.
I duplicated the images on this faulty tape with
"/usr/openv/netbackup/bin/admincmd/bpduplicate -dstunit dlt-robot-tld-0
-id BK0016 -s 03/01/02"

Listing the images on the offending tape BK0016 shows the following...
"Backup-ID            Class      Type  RL  Files   C  E  T  PC  Expires

The backup started on BK0011 (frag 1) then moved onto BK0016 (frag 2).
It appears that the duplicate of media id BK0016 has also included
fragment 1 on BK0011 since the KBs of the two fragments add up to the
image duplicated on BK0002.  But then the above says copy 2 on BK0002 is
just fragment 1!  Can anyone make sense of this? :)

Perhaps there is a better way to duplicate a faulty complete tape?

Many thanks, Justin
