thinkpad backup solutions

[Alden S Klovdahl <Alden.Klovdahl@anu.edu.au>]

wondering if anyone can suggest a good backup solution for a thinkpad.  i
won't specify which because i would like something as generic as possible. 
the following is what i am looking for (and probably so is everyone
else!): 
   
1.  portable:
    a) small and light
    b) power source, with most desired at top
       i. draws power from thinkpad (eg, keyboard/mouse port)
      ii. has small/light universal power adapter
     iii. adapters available for different countries (110/240/etc)
2.  reasonable capacity (1GB+)
3.  works with dos/win(3.11)/NT/linux/unix/mac
4.  not too expensive

suggestions welcomed and appreciated.

regards, al
