> The idea of a multidatastore is to decorate two datastores. It can be used to 
> implement a Primary/Archive DataStore.
> New binary files are saved into the primary. A archive task would move files 
> from the primary to the backup datastore. Reading from a MultiDataStore is 
> transparent to the jcr api. So it will always return files either from the 
> primary or from the backup datastore.
> The primary datastore can be mapped to a fast storage medium and the archive 
> to a cheap sata or a tape library.
