The best argument is that you have the hardware and software on-site for disaster recovery.

It's not a failover situation but it does mean that production would be down for hours instead of days.

We currently have a production, system and development database here. The system and development databases are purged periodically and reloaded with lookup data. The developers are then responsible for entering transactional
data in both regions. I am looking to follow the same practice for development, however I would like to clone my production database directly to
the system test database. The production database is ~75G. Management does
not want to commit $ to a full sized system database. Costs outweigh the benefits. I would like to sway them. HOW? Please give me your costs/benefits
of doing this. In addition, what is the norm (if there can be one) in other
shops. Does utopia exist?

ps. One of the biggest reasons for this database would be for benchmarking,
timings, stress-testing. I realize I can copy the production stats, but that
won't give me a good execution time. Do others load a subset of data (say 25%)
and then extrapolate to a total time? Is that even necessarily accurate to do?
I have my doubts. Thanks
