(some lakhs of transactions/milli sec will be going on).Data loss has to be minimized to the possible extent/ should be eliminated.
performance is a criteria.
Thats too much of data, more than 100 million records per second!! Trillion of records per day!! Seems only bulk operation is happening here.... I'm just guessing the size of your database... and number disk arrays....
If this is such heavily used database, i dont think plain backup-recovery options would suffice. You must have strong DR solution in place as well.
I think if only bulk data is pushed, bulk-logged recovery model will be suitable.
