If you like to burn DVDs, then taking a small compact laptop with built-in DVD or BlueRay burner will be a better choice. At least you can see and select what you want to burn on the DVD. The MFR does not have a screen, and needs to be hooked up to a TV or computer to see the photos, not as cool or versatile as a laptop.
Using flash drive or small compact external hard drive to back up photos will have have worse problem than MFR, you can't see or view the photos unless you hook it up to the computer/laptop.
Using a photo/multimedia device like Epson, Wolverine, Jobo Giga Vu pro, Nikon Coolwalker, etc is a fancier version of a external flash or hard drive with a nice screen. The advantage is its compact size and fast downloading of photos, with the ability to view photos (even the RAW files). But if you like to travel with a laptop, then you won't need this type of device. One problem traveling with the laptop is that you can damage it during traveling, and costs more to replace. The laptop may also contain your own confidential personal identity profiles and can put you at risk of identity theft if someone steals it. So do not bring your regular main laptop, and do not load any personal information on the traveling laptop.
