> The idea of a multidatastore is to decorate two datastores. It can be use=
d to implement a Primary/Archive DataStore.
> New binary files are saved into the primary. A archive task would move fi=
les 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 arch=
ive to a cheap sata or a tape library.
