Today’s Tip…

NTFS deduplication allows us to consolidate redundant data by file data to the ‘chunk store’ and keeping a single copy of each data chunk. The exception to this is when a data chuck is referenced by 100 files or more. When this occurs, the chunk in question is called a ‘hotspot’ and redundant copies of that chunk are created/maintained. To find out if your deduplicated volume has hotspots, you can use the Windows PowerShell cmdlet, Get-Dedupmetadata.
