witch Posted June 17, 2015 Posted June 17, 2015 I am looking at sorting this out on my new Server 2012 but it doesn't seem to be in the list of things when I run the "Add Roles and Features Wizard" as per TechNet instructions What have I missed?
localzuk Posted June 17, 2015 Posted June 17, 2015 It should be under "File and Storage Services" -> "File and iSCSI Services" -> "Data Deduplication". 1
witch Posted June 17, 2015 Author Posted June 17, 2015 (edited) Nothing under iSCSI which is why I was following the add roles wizard Edited June 17, 2015 by witch
halbaradkenafin Posted June 17, 2015 Posted June 17, 2015 You can do it through Powershell with the command: Install-WindowsFeature FS-Data-Deduplication It might error out if you don't see it in the Add Role Wizard but it's worth a try. It might also need to be run as administrator. 1
witch Posted June 17, 2015 Author Posted June 17, 2015 S'OK Don't know what I was doing but it is in the wizard list now
witch Posted June 17, 2015 Author Posted June 17, 2015 Yes It definitely wasn't - I even got someone else to check The power of edugeek!
GuyJD Posted June 18, 2015 Posted June 18, 2015 Sorry to hijack the thread but I'm setting this up too, I've got a 2008R2 server and a 2012R2 server that replicate shares, if I set this up on the 2012 server will I have any issues with the data on the 2008 server? I'm a little worried about firing it up as I've never used dedup before in a live environment.
Steve21 Posted June 18, 2015 Posted June 18, 2015 DFS Replication Data Deduplication works fine with Distributed File System (DFS) Replication. Optimizing or unoptimizing a file will not trigger a replication because the file does not change. DFS Replication uses Remote Differential Compression (RDC), not the chunks in the chunk store, for over-the-wire savings. The files on the replica can also be optimized by using deduplication if the replica is using Data Deduplication. Steve 1
GuyJD Posted June 18, 2015 Posted June 18, 2015 So the data on the 2008 server will remain the same and not deduplicated?
localzuk Posted June 18, 2015 Posted June 18, 2015 So the data on the 2008 server will remain the same and not deduplicated? Yeah, that sounds right. DFS doesn't interact with the dedupe stuff, so it is only copying the "files" when it replicates. 1
ataylor Posted February 10, 2016 Posted February 10, 2016 Currently looking at implementing deduplication too, biggest worry is with DFS, do I need to install deduplication on both data servers? Thanks
localzuk Posted February 10, 2016 Posted February 10, 2016 Currently looking at implementing deduplication too, biggest worry is with DFS, do I need to install deduplication on both data servers? Thanks In simplest terms, yes. In more complicated terms, I believe DFS is file based copying, so it can be mismatched, but the other server would have to have space equal to the non-deduped data size.
truebluesteve Posted February 10, 2016 Posted February 10, 2016 A bit of useful info about what is and isn't included in Deduplication (according to MS) Deduplication is not supported on: System or boot volumes Remote mapped or remote mounted drives Cluster shared volume file system (CSVFS) for non-VDI workloads or any workloads on Windows Server 2012 Files approaching or larger than 1 TB in size. Volumes approaching or larger than 64 TB in size. Deduplication skips over the following files: System-state files Encrypted files Files with extended attributes Files whose size is less than 32 KB Reparse points (that are not data deduplication reparse points)
SHimmer45 Posted February 10, 2016 Posted February 10, 2016 Doesnt you backup solution need to be deduplication aware as well
localzuk Posted February 10, 2016 Posted February 10, 2016 Doesnt you backup solution need to be deduplication aware as well Yes and no. Yes, if you want the data to be transferred in a deduplicated from from the originating server to backups. No if you don't mind it being unsquashed and then sent to the backup solution. Some solutions have their own deduplication built in, which is incompatible with Windows deduplication. 1
ataylor Posted February 10, 2016 Posted February 10, 2016 So essentially DFS does not see the deduplication? it follows the pointer as such. Also interesting regarding the backups.
Areku Posted February 11, 2016 Posted February 11, 2016 Hey I've been looking into dedupe, and have noticed our file server (2012R2) is not deduping. Anyone know if its safe to turn on, on an active file-server?
Steve21 Posted February 11, 2016 Posted February 11, 2016 Yep, only thing is if you set things like thorough processing it'll kick into action and use CPU etc, so either set background or wait till it's being used less Steve
