hi

its probably about 10 TB per site per night, 200 clients each site,  
oracle is the main data source, most will be SAN based.
There are a small number (<20) apps at RPO/RTO= near zero, which are  
cross site clustered, most other HA/DR is 4hrs, and backup needs to be  
one of the HA apps because of the potential requirements to recover  
other apps, also that apps might move from prod one site to prod at  
the other site and we need to track backups. Pipe is 2 x 10GBE,  
business is telecoms.

Essentially i want these two sites to act as one site.

regards
mark
