If your backup command has saveset=all, then the short answer for the
cloning of same to my knowledge is "no."
If you are looking for a long term solution that involves splitting the
backup, I believe the closest you can come is determine backup size of
your data directories and setup separate backups/clones of the same host
splitting it up by directory level. DPA can help you plan this or if you
do not have DPA you can manually figure this out using mminfo commands.
Backup1/Clone1
Host007\ONE
Backup2/Clone2
Host007\TWO
Your choke point then becomes your network. Is your network setup so
that you can saturate two LTO3, LTO4, LTO5 or EDL device interfaces? If
yes, KUDOS and please share your network design with us. I hope this is
helpful.

Subject: [Networker] Can a manual clone job use more than 1 tape volume?
Concerning big save sets: NW needs to keep track about the 'segment's
location and sequence. It is not possible to spread a single save set's
data over multiple media simultaneously. This is obvious as NetWorker
could theoretically split such save set and start with 'segment_x' on
tape_2. However, it would not know in advance whether all data up to
'segment_x-1' would be successfully written on tape_1.
I am pretty sure that NetWorker can not even spread multiple small save
sets from the GUI to different media. But it might do so if the other
parameters fit as well (small Target Session value for the tape drives
etc).
Best practice i would use is to run multiple nsrclone commands/scripts
for this purpose.
Using the command line you can of course also clone directly to multiple
clone pools which the GUI does not offer you (unfortunately this is
rarely an option).
