- There is a scheduler which runs one deduplication job / operation at any point in time
- Powershell and windows commands add jobs to the scheduler queue - only one job may run at a given point in time
- Types of deduplication operations:
- Optimization - deduplicates files on the filesystem.
- Scrubbing - performs an integrity check of the deduplication store
- GarbageCollection - files deleted from the filesystem do not automatically free up space on the disk. A garbage collection must be run to clean up the dedupe store
- You can configure the minimum age of files to deduplicate. Typically this should be set to a value greater than one day to ensure active files are not deduplicated.
Here are some handy powershell commands for managing deduplication on Windows Server 2012:
# Enqueue Full integrity check of the dedup store
Start-DedupJob -Type Scrubbing -Full -Priority High -Volume D:
# Enqueue Garbage Collection of dedup store - deleted files won't reclaim space until GC is done
Start-DedupJob -Type GarbageCollection -Full -Priority High -Volume D:
# Get running / queued dedup jobs
get-dedupjob
# Get dedup summary status
get-dedupstatus
# Enqueue the optimization job
Start-DedupJob -Type Optimization -Full -Priority High -Volume D:
