Best Backup for unraid

[kvnwds43]

Hi guys I'm just about to build myself a new nas which I'm going to be storing my home blu ray and dvds on in mkv , I'm going to have approx 8tb of media to start with what's the best Backup solution for unraid.?
I will be useing a parity drive but i know that's no guarantee of not losing everything.

I'm new to nas so bear with me lol.
Should i even use a backup solution to store these items on there?
I'll be useing plex as well as streaming to a vero box, the media are all what i own by the way.

Any local solution simply isn't a proper backup - you need either a cloud solution or a physical copy kept off-site!

The parity drive in unRAID is great in case of a single drive failure (or multiple if you have multiple parity drives) but a backup meeds to be elsewhere!

Personally I backup my vital data to a portable USB drive from time to time and leave it at my parents house!

Which cloud solution do you suggest.?
I've heard of crash plan.?
