Windows server 2012 deduplication

-

hi,

i'd grateful if provide definitive answer this, frankly it's driving me loopy. have 2 x server 2012 (not r2) servers. 1 physical full gui. other hyper-v guest, server core, guest running off 1 chunk of san storage and a cifs share scsi attached .vhdx on chunk of san storage.

both have dedupe turned on. gui server has stats related dedupe, , backups our backupexec agent. core (virtual) server... doesn't have stats. did 10gb freed up, down 0. every time tries run

both servers had fs-fileserver, fs-data-deduplication , fs-resource-manager roles installed. physical box had fs-vss-agent installed. core has role installed.

the core box never runs dedupjob without complaining doesn't have enough ram (which rubbish, 'cos it's server core box 4gb ram- identical physical box). a remote explorer session also mis-reports on terabyte of data stored in few gb on disk (i remote explorer, because the remote storage tools know there's 5.1tb of 6tb disk taken hasn't fooled windows entirely).

does know why deduplication stats bad- lack of fs-vss-agent, or because disk vhdx sat on san storage? , ideas why it's mis-reporting actual size vs size on disk?

hi all,

thanks responses- , can report (a bit bizarrely) that, reason, has started working. have no idea why; scrubbing had kicked in (once week) can't that, anyway it's cleared down 1.48tb (29%). background optimization job no longer

strange. anyway, on this.
