Review comment:
I am using a DAO (Data access object), did you mean using a JPA queries
(with ACS' home made JPA implementation)?
But if volume is deleted, how can we find its snapshots? I mean, aren't the
snapshots of a volume deleted as well?
Are you sure that we use only the files in the secondary storage to build
the template from a snapshot? I was under the impression that it was being used
the primary storage as well.
