Current Issue: File Cluster Disk of 14 TB Size needs an CHKDSK which can't be done because it lasts too long. So I'm going to replace this disk in the storage of the cluster. I run many times the copyjob with robocopy. No problem at all till I saw a big difference.
My Issue: The new disk with the copied data needed 1 TB more diskspace than the original one. Is that caused by Dedup? I've deleted the volume and will restart the copyjob.
Env: Windows 2012 Server (no R2!)
Current Disk: Deduplication Active
New Disk: Copied files with robocopy
robocopy I:\ E:\ /E /COPYALL /PURGE /MIR /B /R:1 /W:1 /LOG:C:\Temp\robocopy\logfile.log /NFL /NDL /NP
Should I exclude with /XP the System Information Volume? When I check the volume with treesize, it shows that 95% (on both drives) of the storage place is used from system volume information.
Deduplication is automatically active on the new drive. So what do I have to conisder for a safely way to copy my data?
