Deduplication - anyone else using it?
We've been transferring all our data from a Windows Server 2003 machine over to our new Windows Server 2012 machine and one of the features I'm loving is dedupe, and how simple it is to use.
Anyone else using deduplication on their servers now? Not necessarily with 2012.
What sort of savings are you seeing? We're hitting a 25% deduplication rate here. Which is pretty good, considering we've not moved everything over to that server yet either.

We are looking at transferring over summer and using it. I ran the analysis tool on our existing data and we were seeing similar results, around 28%.
One of my queries on it has been backup, if your original data size is 100gb, and deduplicated means its 75gb, what is your backup size? Presumably 100gb?

The backup size depends on the tools you use for backup. If they support Server 2012, they should be able to use the optimised backup option, which would mean your backup would be 75GB. However, if they don't support it, it would be 100GB.
The technical(ish) details of it are here - Backup and Restore of Data Deduplication-Enabled Volumes (Windows)

Ah great thanks, we are looking at implementing a new backup system too that would be DPM 2012 so in that case our backup sizes should be reduced too. Obviously with incremental backups it gets a bit confusing and things I don't even want to think about!

I took all our file server on a test box and enabled it and we where saving 30% ish. We use DPM 2012 SP1 for backups, but i didnt test the backups to be honest.

Not live with it yet, but on our data drive the tool told us 39% reduction in space without compression, which is phenomenal, and almost worth the aggro of having to work with Server 2012. Our roaming profile data was more than halved without compression, though I wonder if it's a net benefit (less data) or net harm (more file work?) to the SSDs. Probably unlikely to massively impact either way, tbh, and the SSDs have ample endurance to cope anyway.
You can't make me use 2012 anywhere else though, no you can't. (Though I'd probably use it for virtual hosts if I was virtualising now, but I'm not messing with my existing setup)

@sonofsanta How do you mean?
You can't make me use 2012 anywhere else though, no you can't.

Server 2012 is a far superior server OS than 2003, 2008 or 2008 R2. It is faster, has a far improved I/O system, better network performance etc... Don't know why you wouldn't want to use it!

But... but... the interface!

I don't think I've been in the 'metro' bit for more than a few seconds at a time...

Even then, it seems to occasionally decide that no, you can't layer that particular combination of windows in such a way that you can keep an eye on them all at the same time. Maybe it's just because I've only ever dealt with it in fifteen minute bursts and never forced myself to actually work through the nausea, but still, the very notion of a touchscreen interface on a server OS makes me itch all over with horror.

To be honest everything should be done on remote consoles on a client. You should hardly ever need to log onto servers. I hardly ever log onto servers.

you can get to all you need from server manager ad/dns/dhcp without ever going into metro and metro sucks for about a fortnight then it starts to make sense imo

We have sedum on our SAN, it's fantastic

In regards to the backups of de duped drives, is anyone using them with cloud based backup systems which do their own de duping and how it affects backup sizes?
