I'm a programmer and what goes on in the data centre is a mystery to me, so this question might be very very stupid.
If you have multiple backups of the same data, and you "de-dupe" it, doesn't that mean you now only have one backup of that piece of data, so only one point of failure?
How does that help? Surely if you're running full backups you want discrete copies rather than de-duped copies, which are more-or-less equivalent to an incremental backup?
And, conversely, if you want de-duped backup data you just run an incremental backup in the first place, without paying anyone a dime for de-dupe techonology.
What am I missing here? De-dupe sounds like a stupid idea for backup data.
Paris, because I wanted an icon with a question mark on it, and I can see the IT angle.
