I've been using an external USB drive for backups for years (more specifically, a regular HDD in a USB enclosure), it works reasonably well. I use ext4.
ext2 is more prone to lose stuff and become corrupted if your PC shuts down suddenly as it does not have journaling.
ext3 has journaling but is a bit slower than ext4, in my experience
ext4 works well and is able to recover from crashes and is a bit faster than ext3.
