That would be formatting the stick to ext2... not ext3

Sounds like a lot of bother. Since the OP is using this for backup,
what's wrong with simply packing the files, *nix attributes and all,
into a tarball, cpio, whatever archive and simply storing that on the
vfat filesystem?

Essentially, yes. But to avoid confusion, I worded it the way I did.
Also, there are distinct, but minor differences, between the two. Ext3
is not just ext2 with a journal.

Here's a quick overview of several Linux filesystems, including ext2 & 3:

I have ext2 and ext3 and vfat files on the same vfat flash drive. I can't
say about archiving. Otherwise, works fine. Provide umask access for
reg users when mounting drive and they too can copy from key.

Actually a usb stick might be one of the smarter places to use
a journal since it may be yanked out at any time, possibly without
unmounting. The journal will reduce the chances of corruption and loss.
Not that I'm in any way suggesting that removal with unmounting is ok.
