What are you guys storing that is TBs in size and needs to be replicated?!

Nothing in TBs, I'm probably under 250GB in total, my wife might have a chunk for her business(es). I'll also be a remote rsync destination for my brother (who might be 250GB or so), and possibly my other brother, and my neighbours, etc. 3TB is about the minimum with a 4-drive NAS so that'll do nicely for me.

Even so. Mirroring stuff at home doesn't increase redundancy that much. Burglars steal computers, laptops and NASs. If you have a fire, flood or theft, expect to lose your NAS as well as your other devices.

Indeed. Hence my plan:-

NAS = main backup with redundant disk(s)
external HDD = on-site backup in case NAS dies
rsync to brother's NAS = backup in case house burns down

Why a NAS rather than just a couple of external HDDs?
- More than one computer to back up so connecting an external HDD to each and every machine each time is a pain
- Also useful to have a simple always-on computer as a central store/host for various things
The NAS can also be used as a central store for things I don't need backed up, e.g. holding movies for streaming to laptops, etc.

To be honest, even this is a legacy arrangement as I don't tend to store anything locally now and am moving to a cloud to cload backup arrangement. Surely the ideal endstate is to not have any data stored at home at all rather than mess around with NAS devices?

It's a nice idea, but I'd still want to be in possession of a copy of my data. I'm not ready to trust it all to the cloud (or multiple clouds for the data that needs to be backed up).

I actually have a NAS (well 2, one Synology, one running MediaVault with docker images as well for fun) but I also cloudback up.

For photo's they are backed up directly to Synology AND Crashplan (at the same time), then sync'd from Synology to Amazon Photos.

For my documents sync'd to Crashplan only.

Anything going to crashplan is encrypted locally. Honestly, I've had to restore from CP before and while it's a little pricey now at $10 a month, having UNLIMITED versions is very VERY useful.

Don't fall for cheaper backups, which after a period of time will hard delete anything you've deleted. So not really backups but more of a sync (and yes that's people like Carbonite etc...)
