I would get one with a real harddisk instead of a thumbdrive. More
capacity and probably a longer life.

Using USB drives, there might be a way to completely automate
backups. Using devd(8) it should be possible to detect that one of your
backup disks is being plugged in. This can then start a script to mount
the disk, perform the backups, unmount it and give the user a signal on
the console, or audible, that he can take the USB drive out.

If you're going to use thumbdrives, think about security. Such small
devices are easily lost or stolen. Either encrypt the individual backups
with programs like ccrypt(1) or gnupg(1), or use an encrpyted filesystem
layer like geli(8).
