Thanks Andrew, I am already trialling the d2d and dedupe with Commvault (our current product).
Don't misunderstand me, I'm not suggesting I'm dealing with flat-earther's and they aren't suggesting "don't' do it", I just found it a bit of an odd stance how they seemed inherantly distrusting of dedupe "because it's a database" whilst no-one questions the numbers in a financial system that is held in a database, or if they do, the assumption is the input or the formulae are wrong, nobody ever questions if the database has stuffed up and randomized a value etc. I'll happily admit myself that I'd still want to take traditional full's every so often rather than rely on a single full and then "incremental forever", and I'd still be looking to spool the deduped backups to non-deduped tape.

The basic concepts of data deduplication is used in a lot of places, not the least of which are compression algorithms, data encryption, WAN optimization, etc. I think that the technology is mature, and that there's a lot of impetus to do it right, in general. Unless they're going to suggest that they don't trust ANY data in non-native format, they'll have to concede that they accept all sorts of data abstraction for other reasons on a regular basis. This one saves both time and disk space. You should speak to your favorite vendor in this space and get a pilot, so you can see/smell/feel it in action for yourself.

They're a little mistrusting of dedupe on the basis "It's a database it can go wrong", to which my retort was largely a combination of having to have faith in an established vendor, combined with "If a database gives you a value you assume it's correct, you don't think "what if the database has corrupted the value" because you have faith in the checks and balances that ensure the data is atomic". So, what are you views on dedupe when it comes to backups? ________________________________ MIRA Ltd ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin -- MIRA Ltd Watling Street, Nuneaton, Warwickshire, CV10 0TU, England Registered in England and Wales No. 402570 VAT Registration GB 100 1464 84 The contents of this e-mail are confidential and are solely for the use of the intended recipient.
