Excellent inputs. Thanks to all of you !!
Salem, if you have a descent size database than it's quite dangerous option. I mentioned reference to my blog in previous post - if you read it you will understand why. Even short interruption in connectivity to remote site might cause ASM to start rebalancing and recovery from this is a non-trivial task.
Replication via Oracle Data Guard or third party tools is a much better option. Just storing backups remotely is a much more reliable alternative than distance storage box with ASM.

'failover' disk group. It's very easy to setup.
