Duplicate Files Deletion

Are there any way to optimizing storage by deleting duplicate files automatically? Any recommendations will be appreciated.

Hi @sprmachtmann,

Can you provide more information? Your question is generic and adding more information would assist the community with providing you with some recommendations.

I would start by:

Defining your definition of "optimizing storage" - Some would say "just enable de-duplication" assuming this is not enabled.
Providing more information about your platform - AFF/FAS/CVO/etc
How you are seeing duplicate files and your ideal end state.
Do you have any constraints around installing software or using scripts for this process?

That is a start, but more information will help those trying to help you..... and I hope that this helps!

Hi @chamfer ,

Environment runs on AFF system. Our ideal end state is every duplicated files will be reduced as non-duplicated.

No restriction or avoidance for any software or script.

Hello @sprmachtmann ,

As mentioned by @chamfer , can you validate if deduplication is enabled for the volumes in your AFF cluster. I am herewith attaching a documentation that details about enabling deduplication:

http://docs.netapp.com/us-en/ontap/volumes/enable-deduplication-volume-task.html

You can also validate if the storage efficiency is enabled for a particular volume by running the command:

::> volume efficiency show <vol_name> -instance
