2. Deduplication?
Architecture
Installation - Config
Results / Conclusions
More Tips

5. In-line versus Post Process
Source versus Target
File-, Block- or Chunk-Based

7. Filter Driver
Service Based (ddpsvc)
Garbage Collection
Optimization
Scrubbing

10. Windows Server 2012
1 single CPU – 4GB Ram - SATA

11. GUI Based
Through Server Manager
PowerShell
Import-Module ServerManager
Add-WindowsFeature –name FS-Data-Deduplication

13. Can it be duplicated?
Empty volume?
Resources?
Unsupported Config?

14. Great:
{ File share | Virtualization Files | OS deploy files | Backup Files }
Maybe:
{ LOB | Web Servers | HPC }
Poor:
{ Hyper-V hosts | WSUS | SQL / Exchange Servers}

15. 5 Age default (last modified)
Schedule: every hour
No exclusions
Garbage collection /
data scrubbing on Saterday

22. Capacity optimization
Scale & Performance
Reliability & Data integrity
Bandwidth Efficiency w/ BranchCache
Management w/ Familiar Tools

25. Backups

26. DDPEval <VolumePath:>
Examples:
C:> DDPEVAL.EXE ServerTestshare
C:> DDPEVAL.EXE E:Test
C:> DDPEVAL.EXE F:
Will produce output similar to the following:
