2TB NAS Vs 6TB NAS Raid 1

Specs: Windows 8 64 Bit, 16GB DDR3 1600MHz Memory (4x4GB) Kit

I have around 500GB of things on my PC that I need to backup and around 600GB of films on a media server. Currently they are backed up using SyncToy to a 2TB NAS. Very important documents are being backed up to DropBox also.

I am considering replacing my 2TB NAS with a 6TB NAS and setting as RAID 1 so I have a back up of a backup? Is this a better option than just having what I have at the moment?

A second NAS is probably all you need unless you want an off site backup. I never needed RAID

RAID 1 will help you if something happens to a disk drive.
RAID 1 will not help if something happens to the NAS.

Don't think of RAID 1 as a backup. It's purpose is to maintain access to your data in the event of a drive failure. Drive replacement can then be deferred to a more convenient time. On a busy server that is an important feature but on a home network that is much less of a concern.

RAID 1 isn't a bad idea, just be sure you are using it for the right reasons.

But if my primary files are stored on my computer HDD, and media server...
Then their backed up to a NAS drive in Raid 1 surely I would end up having two back ups rather than just the 1 like I have at the moment? I know Raid is about redundancy but im thinking 3 copies is better than 2 :D

You shouldn't think of something on RAID 1 as being two separate copies; it isn't. It's one copy with a chance of recovery depending on the nature of the failure.
