Best method for External HDD backup

[Bry]

I have around 2TB Of data spread across 5 internal discs which I need to backup and this grows by around 2-3GB of week. Files are mainly media files such as Photos and Videos however, there are also other files like word documents, excel files and zips.

What would be the best method of backing this up?

Single external discs - this would take up a fair bit of physical space and would have the inherent problem of drives filling up.

Separate Server PC in a Raid - Not really wanted due to size and power consumption.

External Raid box - Products like Synology and Qnap 4bay raid boxes. However, I am worried about what happens if the actual raid box dies. Yes it will be a backup box so the data is not lost. But, if i remember correctly I would need to buy exactly the same model in order to recover the raided data as I could not simply buy another product, put in the hard drives and click recover.

This to me seems a major fault of external raid solutions.

Anyone have any thoughts on a reliable and easy solution for external data backup like this?

hi,
its not really that I don't want any of them, just the fact I can find fault with each method.

I'm against internal raid being used as backup, I really think it is best for overall data integrity to have my backup external.

I think cost wise external separate hdd are probably the best in their own caddies. However, I am still edging more towards a external raid box like the Synology C407 or Qnap 409.

Yet I am weary as I can not find any example of anyone having to rebuild the array after one of these products dies (maybe that's a good thing? they don't fail often)

ah well the reason i would like a proper enclosure is because i dont really want the hassle of keeping swapping the units in and out of either the enclosure or the connections

Unfortunately there doesnt seem to be a 3-4 disc external caddy
