With split-mirroring or snapshot solutions (EMC or NETAPP or anyother
vendor) when working with ASM you need to carefully layout the Disk Groups.
For example you should (or shall I say must) NOT mix databases in same Disk
Groups, because when you run the snapshot you will be backing up all
databases in the Disk Group, that is not a problem. The problem is when you
have to restore, when you restore a snapshot you will be restoring several
databases!
