Hey guys. I was wondering if anyone could help me figure out how to set up a backup solution in my home. I recently lost about 4 years of data, and I have some spare cash, so good a time as any I suppose. I want it to be reliable, so I did some research and I feel comfort in RAID10, for it's mirroring and striping. 

I have never worked with any sort of backup solutions like this, so I don't know where to begin. What drives should I get, should it be a physical drive backup, or should I build a home server to facilitate it as a NAS? Any help at all is appreciated, advice as well, as my knowledge here is nearly zero.

P.S. I'd appreciate you keep this semi professional. I'm not a fan of asking for sincere help and receiving backlash like "that's stupid, why would you do that". Thanks.

How/why was your data lost?

You have to think about the perils you need protection for.

The value of raid-1 and it's variants like raid-5 is that you can recover from a drive failure quickly. It is for servers that can not tolerate any interruption.
Modern hard drives have a advertised mean time to failure on the order of 500,000+ hours. That is something like 50 years. SSD's are similar.
With raid-1 you are protecting yourself from specifically a hard drive failure. Not from other failures such as viruses, operator error,
malware, raid controller failure fire, theft, etc.
For that, you need external backup. If you have external backup, and can tolerate some recovery time, you do not need raid-1
