In a camera, it will be subject to the limitations of the camera's firmware.

In a PC, it won't.

FAT limits file sizes, access permissions and lots of other stuff. So
backups via rsync or something onto FAT would be a big problem.

But if the OP were backing up into compressed files and the backup
tool could cope with segmenting them into 2GB chunks, it'd work.

It's still a faff, though. Better to format the cards as ext2 or
something. (Journalling is just a waste of Flash cell rewrite cycles,
so ext3 and ext4 are contra-indicated.)

OTOH, SD card interfaces are often slow and capacity still limited and
expensive. For backups, personally, I'd be looking at
grandfather/father/son (i.e. 3 drives) and big-capacity conventional
hard disks in USB3 caddies.
