I currently have some data (about 1TB) I need to backup but I need some help with implementation. I was originally thinking of just buying a NAS but then I would still need a backup for that as RAID != backup. A simple option would be just to buy two external drives; however, I feel keeping the two drives' contents synced would be a pain especially considering my computer does not have USB 3.0.
For the drives I was planning on buying two of Seagate 2TB NAS drives and I was hoping to not spend more than $600 USD for the drives and other hardware together. Any suggestions?
