Currently we have a 1.5Tb (70 volumes) SAP client backing up (directly) to
tape.
We would like to use TDP for ESS i.e. flashcopy for such (large) clients.
If I understand correctly flashcopy (with COPY option) works as follows:
*       flashcopy initiation (establishing pairs) for 70 volumes .......
this only takes 2 à 3 seconds per volume.
*       then in the background the actual copy takes place.
How long does this background process take ?? What does this mean for
performance during SAP transactions ??  
*       during this background process you could already start backing up
(the copy volumes) to tape !!!?
Is this true ??

*       how to recover from a SAP database corruption without restoring from
tape ??
        because the COPY option was used you can perform a 'flashback'
......?
        it would be nice to have a kind of "TDP for ESS Restore" cause TDP
for ESS 
        nowadays is only focused on Backup !!!
