Pete,

At a previous job we used the BCV method to move a copy of our production system to the reporting system every night. Started at midnight finished half an hour later routinely. Somewhere between 500 and 800 GB. Was scripted and ran lights out every night like clockwork.

Thanks for the thoughts. We are likely going to be refreshing and rebuilding at least three multi-terabyte databases every month for development. Same for systems and integration testing. Speed is definitely an issue.

We would also like to reduce the number of DBA resources required to do this. That is what originally drove the Symclone question. Can we do this with little, or no, DBA time? There seems to be agreement that it is slow. Guess we need a 'Plan B'.
