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.

Subject: Re: [ADSM-L] Restoring dedupped-backup from VTL

So, what is the best practice to use VTL+TSM? 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 :(
