To do a back-up of a directory tree, I

I do not know what the system does "under the hood" to do the copy.
If you're going to do backups with such a simple technique, you really
want your USB stick to use the same filesystem as your original files
were stored on.
If it's (sufficiently) different, you lose permissions and SELinux
contexts, and won't be able to copy very large files over. By
sufficiently different, I mean things like to trying to copy an EXT3
file system's files over to one of the FAT formats that USB drives
usually come preformatted as.
But for something that's almost the same, like copying an EXT2
filesystem's contents over to a drive using EXT3, or various other
common current Linux filesystems, you're probably going to be fine.
