Thanks for the link Chuck. As a New Yorker also dealing with the lovely winter I agree the tweets from the VI get under my skin.

I'll be posting my thoughts on the backup post next week. Too good for a mere comment.

Long time no chat. Disclosure: I don't sell any of this stuff.

The reason your backup post tweaked so many people is that it suggests that there are vendors promoting the idea that having ONLY a local copy of data is a valid backup. There is not a single vendor on this planet promoting that idea, and any SE or salesperson promoting anything of the sort would/could/should be immediately fired.

What you do see vendors promoting is that the idea that a truly local copy (even if its virtual, such as with a snapshot) is the quickest way to recover from the majority of failures (which are caused by user/admin error). But if you plan to protect against other types of failures, you'd better replicate.

And yes, I would call a local snapshot (even a virtual one) a backup.

Hi Curtis, good to hear from you.

I think everyone would agree that local copies sure make life a lot easier for recovering corrupted data -- that's not the point here.

More directly, we routinely engage with customers who tell us -- in all seriousness -- that their vendor told them that local copies would be all they needed.

It's more than a few outliers here and there -- it's becoming a consistent pattern, and an unfortunate one.

The real point, at least for me -- what do we as vendors owe our customers in terms of full disclosure around the various risks of different approaches?

And that's an area where we all could improve.

I'll have to take you at your word on that. I can honestly say in my 18 years in this business, I've never met anyone other than an end-user who didn't know what they were talking about that would recommend such a thing.
