I'm pretty sure that once you make a VTL to VTL replication TSM wont know about 
the copy you created because it wasn't copied by TSM (i.e. not in the TSM DB).  
The only way to access is if you are replicating the TSM DB and Logs to the 
offsite as well so TSM will be aware of those VTL vols. 

We thought of doing that but elected to put use the offsite VTL as an Active 
Offsite Copy Pool so TSM is always aware, we replicate DB and Logs, so bringing 
up on instance on the other side and updating Primary to Destroyed ... And we 
are ready to go!

Hello

I'm assuming you are using the VTL's replication process to do this?  If so, 
I'd assume it would be expired (though that is TSM terminology rather than VTL 
terminology). 

Probably best to ask your VTL vendor.

Hi,
A VTL in primary site copies backup data to remote site asynchronously. If
some backups expire in TSM, what happens to the copy in remote site? Will 
it
be expired or retained?

Thanks
