I did a test on my kingston datatraveler recently, I didn't expect it to survive, but it did. I put reiserfs on it, and copied 394M of data in 200,000 files to it. Reiserfs was sloooow at writing, the device was probably doing alot of work. ext2 was about 10X faster, but there was hardly any free space left at all at the end :)

Considering it surived ReiserFS, I suspect it would last ages with ext2, especially for your backup purposes.

I have a couple of years old USB stick, which was used for swap, and for compiling stuff natively on some small mipsel devices, and generally moving files back and forth a lot (ext3 + noatime).

Still, it works just fine.
