In your home, with your hardware it would be hard to replicate 8TB. You could try what the previous poster suggests and find very cheap online storage.Not happening for under <£100

Free 512GB of online data backup you cant go wrong with that! https://www.backify.com/
Hardly going to touch the OP's 4TB of data and how long would it take to upload 512GB?

Well click on the link, I don't see a free amount anywhere. But $3 for unlimited space should just about cover 8Tb
But yeah the time it'll take...




Its (just) still possible to find 2TB drives for £60, as mentioned above. They were <£55 last week. OcUK are betting they will be £80+ by next week.
