It'll give output something like this:
(NB this is *my* box. Your's will be different)

root@aplacilla ~]# dumpe2fs /dev/sda1 | grep Backup
dumpe2fs 1.39 (29-May-2006)
  Backup superblock at 8193, Group descriptors at 8194-8194
  Backup superblock at 24577, Group descriptors at 24578-24578
  Backup superblock at 40961, Group descriptors at 40962-40962
  Backup superblock at 57345, Group descriptors at 57346-57346
  Backup superblock at 73729, Group descriptors at 73730-73730

then do

e2fsck -b 8193 /dev/hdc1


obviously you'll need to adjust the argument to -b with a listed backup
superblock
