If you will be able to get money for it, I would strongly propose SRDF
in your situation. The idea of Snap Clones seems to me quite risky and
according to my experiences, compared with DG, SRDF is much more stable
and an operation friendly solution for DR. For backup purposes I'm
recommending you using of RMAN together with BCVs. With these two
technologies involved you can backup database of virtually any size in
a few minutes (from Oracle point of view).
