Dedup for media files

Most of my data is media, movies and music. Is there any real benefit to turning dedup on for this kind of data?

No, for this kind of data it makes no sense.

In business areas it makes sense when you store the data from many users... Users do not trust network drives, so the absolute identical sales catalogues and pricelists are stored on several client systems. Our IT department told me with deduplication activated on a filer they shrinked a backup volume of 6TB user data to only 800GB in the end

Thanks for the reply. Yeah, I think if I was using this at work, it would be great for all the office documents on the file servers.

Sorry to repost this link all over the forum but I think it's important. Don't use dedup unless you are 100% sure your hardware supports it. It's very risky and "too easy" to enable:

For media - I copied about 1 terabytes and got 1% dedup space back. It's not worth it.
