I think the asynchronous transfer will solve this hurdle. If we provide virus checking before replication onto migration level 2, we should catch anything ugly before it gets replicated. > > 3.

At some point, we'll need to acquire/partner/develop a utility that collects the "live" files from the tape volumes (or whatever ML2 is), and re-create new, fresh, high storage efficiency volumes. > > 4.

I think he's concerned about the "letter of the law" on re-write-ability requirements for legal markets. No big deal as of yet. To your point, one of the recipients of legal data on the back end could be CD-R - which can't be updated or appended. > > 6. They mention multiple 200Mb/s streams.

He means using disk as a collection/consolidation point for network backups. We do a nice job of meeting his requirements on this one, and it may be worth further exploration to make sure we hit the bull's eye. > > > > > > > > > > --- Dan Oister <dan.oister, home dot com> wrote: > > Team, > > > > I'm still a road warrior, but continue to get > > validation at every presentation I go to. > > > > I had some interesting feedback from a gentleman who > > runs a large reseller in England that I'd like to > > share.
