Need advice about a basic data backup system

I need a laptop with two hard drives, maybe up to 500gb each. The second one has to be an exact clone of the first one automatically backing itself up quite regularly, maybe once a day.

It is going to be running a couple of cryptocurrency wallets which doesn't take a huge amount of Processing power. Basically that is the entire function of the machine so maybe a core i3-i5 max, but I want the data backup process to be quite fast so maybe an ESATA port may help there So how powerful should the laptop be, should i use SSDs, if so which brands for reliability, what software should I use for the cloning process that isn't a pain in the backside to figure out and use?

Any help would be appreciated. Budget max £650. Remember, it won't be doing anything intensive like gaming etc
 
Do you want an actual backup (other machine so there isn't a single point of failure, protection from corruption) or just redundancy (help with failing drives). Does it need to be a laptop?

If it's the second case (redundancy) you could go for a RAID1 config, can't do better/simpler than that. But know that if you are hit by something like a ransomware it won't save you.

About backup, if those wallets don't use much space you could do that and do cloud backup quite regularly (careful about unencrypted data though, I would research the best solution). Or even a personal cloud (nothing can be faster than your own network anyway). In either case, if you can keep the old versions after each update, it could *really* save you from ransomware.

Raid isnt a backup system though, its redundancy. If you delete the file/ it gets a virus etc it will happen on both drives instantly so you would also want an actual backup system aswell. Although I wouldnt consider 2 harddrives in 1 machine a backup system anyway.

Just redundancy backup on the same machine

Thanks for your answer. Would I go with a laptop with ESATA for the secondary drive or usb 3? Or should I consider removing the optical drive and installing a hard drive there in a caddy? Would this model be suitable for what I need or is there a more suitable one?

I had a laptop at work came in with both hard drives not working. Power supply blew up every hardware.

Second hard drive with external power supply is much safer method, ie, desktop usb external hard drive.
