I recently complete a similar effort.
I chose to separate prod and non-prod clients into different groups and
media pools to minimize the amount of data cloned.
I then replaced the existing incr schedules with level 9. There was very
little difference. The tradeoff is huge on the recovery side, because
you need only the last L9 and full savesets/tapes to rebuild a system.
I am now cloning daily, and my mminfo looks back to midnight the
previous day and clones that information.
I also implemented a SCRATCH pool so that I would have only one media
pool to manage and hold tapes coming in and going off site.
- Create mminfo and clone script, logs, etc...
- Create scratch mechanism
- Create off site ejection reports
- Create recall/picklist report
- Create mechanism for depositing offsite tapes and relabel to SCRATCH.

There are two options.
In order to clone what you already have, you are going to need a
scripted solution. A script would consist of one or more mminfo queries
to determine what needs to be cloned, followed by one or more nsrclone
commands to copy the save sets to tape.
The other way would be to move away from incrementals and use level
backups instead. The down side of that is that your daily backups will
be larger than they are now, possibly considerably larger depending on
your data.
