[ADSM-L] using different media for permanent offsite copies

Hi all

Need to know if this is feasible as an idea..

We are about to move to a LTO4 media library instead of LTO3s - by
replacing the remaining LTO3 drives we have with LTO4s...  by marking
the existing LTO3 tapes all 'read only' and putting in LTO4 media for
write operatons etc, eventually our library should then only be
comprised of LTO4 media, with LTO3 media expired and can be removed from
the library. 

We are going to have an enormous amount of LTO3 media after this which
we wont use for the normal backup cycle.  We however do have a business
requirement to have regular (quarterly) full copies of the backups for
permanent offsite archival due to legal requirements.  Yes, aware this
means we would need to have hardware available to read such data for the
next 5 years etc....   

Would it be feasible as an idea to define a second logical library -
call it 'archive' perhaps within my existing physical library, define a
new media pool referencing this logical library which will only be
designated with LTO3, put the LTO3 media in there, and generate offsite
copies to this media?   It would either be an export data operation or
generate backup set to this meda pool.. 

Does that sound feasible?
