SolutionIf you are talking about Storage Mirroring software of HP which is OEM of Double Take company. This software works over LAN monitors any changes to the critical
data and sends the changes to the target server. By replicating only the file changes rather than copying an entire file.
Mirroring is for server to server replication. Snapshots and restore functionality is also available with this software.
Where as if you talk about CA in terms with EVA then it replicates the data from one storage array to another over fibre channel. And this is done at block level not at file level.
Hope the above info is helpful to you.
