(adsbygoogle = window.adsbygoogle || []).push({}); Will I get a copyright infringement if I upload my "backed up" PS3 games and movies I download to a cloud storage because of the space on my hard drive

I really doubt it. I'm not sure however, and you should seek further clarification from other members. To the best of my knowledge you should be okay, but I could be incorrect.

So long as you are not sharing them, and it is just you doing it. You will be fine. You can backup stuff you own.

There’s one part that I find particularly interesting. MP3Tunes uses a method called hashing to compare files its users attempt to upload. Identical files produce identical hashes. This allows them to use a unique hash for every song and “recreate” that song for everyone who uploaded it to their locker. This process is called de-duplication because the company doesn’t need to store an actual copy of the file for each user who uploads one, and it’s a great way to save disk space and bandwidth.

Interesting but predictable. How does this even answer the question given though?

To OP, you should be fine.
