Re: DataDomain archiver with NetWorker?
It is appealing if you don't have dedicated system for archiving (eg. dedicated NW server) and have large number of sessions on daily basis. DDA will eliminate need for nsrstage and like that part. Depening on your env, zfs may be better match - if you are Solaris env and you plan to you disk based solution only then zfs might be better way. Advantage here is that with zfs I can control where so I use dedupe and and where do I don't, while DD box just does it (and we know all data is not fit for dedupe). Using zfs on the other hands will require more CPU power on storage node unit to process that. It certainly depends on your env at the end and overall roadmap of components you run in your park.
