Great post as usual, I do agree with the comment about disk replacing tape for primary backup and restore. I do question that EMC BRS is leading the way and is the best option for customers.
I think if a company wants Backup to disk with De-dupe and has the infrastructure for a separate backup LAN on 10GBe then Data Domain ticks the box. However if they want a VTL then I don't think it fits at all and have seen this in a company I worked for were EMC are now trying to change the support of the box due to major issues with it running as a VTL.

Also is the Data Domain Archiver the replacement for the highly thought of Centera platform which is ageing now or is this something to sit alongside that product?

P.S - Just so I am open, I did work for a leading retailer in the UK but in November changed and now work for HP, but my opinions are my own and not company driven.

Hi Dominic -- thanks for the thoughtful comment.

You're right, there is no one-size-fits-all answer in the world of IT. Specifically, I can imagine more that a few use cases where other approaches would be indicated -- from EMC and other vendors.

Regarding DDA and Centera, the use cases are different. DDA basically extends the disk-based backup into a cost-optimized archive tier. Centera, however, is strong when people actually want to *use* the archived data for a variety of purposes -- search, compliance, customer service, etc.

Customers who just want to replace tape for their deep (and mostly unused) archives will want to consider Data Domain Archiver. Customers who want to archive and use their data for a variety of purposes will probably be more attracted to Centera.

Most people are unaware that Centera continues to do well for us in the marketplace.

Thanks again

Hi Chuck,

Thanks for clarifying the Centera/DDA this makes perfect sense to me now.

So DDA for writing something that they need to keep indefinitely but will potentially never ever need or use again and Centera for say mainframe DB2 data that they need to get off for reference only but will never change it and is the only thing left on their mainframe costing them lots of cash to keep it on there.

I agree on not one size fits all and I probably should have mentioned in my first post that if a customer does need pure VTL then of course you still have the EDL kit at EMC to use for that purpose should someone be adamamant they want VTL and don't care about de-dupe. (look at that a HP employee recommending other EMC kit, dam must be in the wrong job)

Thanks

Dominic
