Moving data from LTO-2 to LTO-4

Could anyone tell me if there's a simple way to move lots of data from LTO-2 to LTO-4 easily? We are getting rid of LTO-2s and I would like to transfer everything to LTO-4 or even LTO-5. I have about...

    Two choices, bupilcate all the images, or duplicate all the tapes - all tapes is probably easier. A list of tapes containing images can be found from : bpmedialist You can then run a loop and feed the tape list into bpduplicate command Eg. cat media_list |while read TAPE do bpduplicate -id $TAPE -dstunit -dp done where 'media_list' is a file containing a list of the media ids.

mph99:

I have often wondered whether the -id option to bpduplicate would do this - the man page is unclear on what it does with spanned images:

"Search the image catalog for backups to duplicate that are on this media ID. If the original is fragmented between different media IDs, NetBackup duplicates only the backups that exist on the specified media ID. Backups that span media are duplicated, but not any other backups on the spanned media ID."
 

The second sentence to me indicates that backup fragments on spanned media will NOT be duplicated.  But the third sentence seems to indicate that spanned fragments ARE duplicated.  Can you clarify?

To answer the orignal question, I would have said duplicate the images:

for tape in `cat media_list` ; do

  bpimmedia -mediaid $tape | awk '/IMAGE/ {print $4}' >> imagelist

done

bpduplicate -dstunit <stunit> -dp <pool> -Bidfile imagelist
 

If you do this, make a copy of the imagelist file, as bpduplicate will delete it, and it will take a while to generate it.
