Too many unknowns to offer any solid advice.

Is this drive only for backups?  Are you planning on a single backup
product to backup both OS'es?  Do you plan on physically attaching this
drive to both systems?  Is sharing the drive over the network acceptable?

There are likely many valid solutions, but without knowing your specfic
needs or intended usage, it is quite hard to make a suggestion.
