The -t option isn't mandatory.
The main form of mount always has been

# mount something somewhere

Where flags are sometimes more clear, but still optional. So try leaving the -t option out:
note: You forgot something, that is the partition's number you want to mount. If there is only one partition on the disk, you probably want this:

# mount /dev/hdb1 /backup

(note the '1')

'-t' is not mandatory if you have got the entry specified in /etc/fstab or /etc/mtab.use 'fdisk -l' or 'cat /proc/partitions' to see all the disk partitions.

Could you give us the output of your mount command, plus the output of:

# fdisk -l

It is a totaly new filesystem
someone has modified some existing filesystem(probably ext2) and made a newer one. let us say "newfs"
Now i want to mount this filesystem.

mount: wrong fs type, bad option, bad superblock on /dev/hdb9,
or too many mounted file systems


fidsk -l gives me
