If it's really Gb buy a second drive and a deck or dock. $61



2T drive is $69

You now have the backup drive and a copy of the backup drive.

After a year (or any time you want), put the first drive on the book shelf, or in a bank box, or offsite... buy another one, back up and you are solid. Cost will be about $70 a year.

CDs and DVDs are unreliable! Your can buy the most expensive Gold and make backups, come back five years later and there's data loss. They are slow.

Personally, I back up photos once a year, from the backup. So I have the last two years of photos on the computer, the backup of the computer all years, on an external drive, and the archived backup of the external drive on a hard drive, that's not connected to anything except when in use.

Video has it's own backup drive, same way, on the computer, on the external and on the backup of the external. Some externals will automatically keep a backup of selected drives and folders, you don't need to do anything except once a month make that redundant backup like the first example.

What I have is the originals, a copy and a backup of the copy. Pretty basic, and never in forever have I lost one file, using hard drives. DVDs and CDs and QIC tapes and Zip drives, I've lost data on every one of those.
