There shouldn't be any problem with ext4. It's been the Linux

would be unless they were trying to make some kind of sparse backup
using FS internals.
I use USB flash drives and 480 GB SanDisk portable drives for some
backups. I started by using ext4 on one of the flash drives. The next
day I tried to boot the computer, but found that the computer hung.
Only at this point did I find out that those drives are not capable of
journalling.
So I either had to use ext4 with the journalling feature disabled or
revert to ext2 for these drives. I chose the latter, as simpler and
less susceptible to errors. I have had no trouble with them since.

That's a separate issue from what the OP asked. USB sticks aren't great
for use with a journaling file system, which would include ext3 (but not
ext2), because you can only write to them a limited number of times.
However that doesn't preclude their use as a backup device even with
journaling enabled.
