Yes, your offsite physical tapes will not be de-duplicated. They will be native size (or compressed if you use drive compression.) We migrate to physical tape as part of daily housekeeping, we do not try to keep all of our data on VTL, primary or copy pool.

Suppose I dedicate all TSM disk capacity available to TS7650 (so there is just one kind of storage pool in TSM: virtual tapes!) and If there is not proper link to D/R site for VTL-to-VTL copy, there remains only one way to transfer backups off-site: using conventional tapes If what I mentioned above is correct, to build off-site tapes de-duplication should be rolled-back when data is copied from VTL to tapes :( IMPORTANT: E-mail sent through the Internet is not secure.
