Keep your life simple!!
You can buy a QNAP or Synology 2 bay (or 4 if you choose). Put two 4/5/ or 6TB Western Digital RED or any enterprise hardrive (stay away from your consumer grade baracuda Seagates) run RAID 1 so your simply going to mirror.
This way you can benefit the optional functionality of a NAS. Access files creating your personal cloud. I'm assuming you have secondary drive in your computer as well.....
Now buy a high quality drive like a WD BLACK or highly regarded HGST drive. Load all of your files to this drive and buy an dock station or hard drive enclosure. Drop it off at your best friends house/ Parents place for off site storage.
Since you have a NAS you have full accessibility of your backed up files. The RAID 1 will be a no brainer mirrored redundancy and if something messes up royally with your NAS you should be able to grab that hard drive and put it in a regular PC to read the files or buy the same brand NAS unit and put those hardrives in there.
Your hard drive you dropped at your Parents/ or friends place is your ultimate offsite backup. It'll take you maybe a hour or so to backup 4tb and your done. Even though I am an Amazon prime member I dont use their cloud service. I just dont have the patience for uploading aprox 5tb to the cloud.
Buying a NAS will allow you to have access of your files in your home effortlessly and I also use mine to upload all of my security video's that I have in my house.
If you have the patience to upload alot of data i'd suggest do alot of research and upload to a cloud. Amazon seems to be a great place to store.
