I store my photos and other important stuff using a Synology NAS. It has four drives in RAID configuration so that if a drive fails, I can replace it without losing any data. It's a very well-designed product - easy to set up and use. Periodically, I also copy really important things, like photos, to an external USB drive which I store "off-site" (outside our house) as an extra backup.I also backup everything to data dvds. I got lazy years ago and lost 8 months of photos when my hard drive crashed. Hard lesson learned!
