For backing up my photos I keep a copy on my computer and on an external drive and back them up to the Internet. Depending on the total size of your files it is free to save to the Internet . I have a bunch so I spend $5 a month. I figure they are worth 5 bucks. Having a copy in another location is a good idea to but then you have to take the files over there. Internet backups can be set to update automatically. I've used carbonate, most, and crash plan.
We' ve considered that for photos, but the videos would take an eternty to upload, and my hubby gets weird about other people having possession, and the freak chance that their electronics fail and we lose them anyway, lol.
