Data Deduplication – Garbage Collection

In this post I will show how you can manually run Garbage Collection on your file server that uses Data Deduplication. Garbage Collection can be run to ‘Reclaim’ the free space after deleting a large amount of data from a disk with data deduplication enabled.

After searching through the Microsoft Docs I came across this page: Microsoft Docs Reference. Scroll down to ‘Garbage Collection jobs’.

I ran the below PowerShell command to start the Garbage Collection task – Replace ‘E:’ with your drive letter.

Start-DedupJob E: –Type GarbageCollection
