Re: [ADSM-L] Backupset media goes to Copypool too?

Yes. And you can forget the consultancy and the arguments about backups
not being archives etc, the keeping hardware and software to run the old
system etc.  Have been through all that with the business.

Data needs to be retained offsite for 25 years.  Its the industry my
company is in.   As a result, I need to generate these archival offsite
tapes - whether via TSM Backup sets or TSM Archives.     
TSM backup sets + TOC appears the quickest way of doing it - and perhaps
a yearly TSM Archive will be run as well (which will then be less
dependant on the tsm server db)
