It stores them in various places, depending on the size of your filesystem.
If your filesystem is large enough (>~ 1/2 GB) you'll probably find it at block #32768.
For smaller filesystems, it appears to put the first backup at block # 8193
You can get more details by using the -n option to mkfs. If you used nonstandard options in your original mkfs, you might want to provide those details here, as well. (( -n has mkfs.ext[23] not actually write to the partition but simply say what it WOULD do if it did. ))
mkfs -t ext2 -n /dev/mydeice

Where does ext3 store the backup superblock? Does it have one at the very beginning of the partition and one at the very end?
