Single External Backup Device for Three Computers

I would like to network three computers to backup to a single external harddrive with eSata connection.  The 500 GB Western Digital External My Home Book Edition HD has USB, Firewire 1394a, and eSata.  I want to use eSata if possible due to faster speed.  Is this possible?  Can I use a Router with eSata connection?  And what software would you suggest? Want to access the HD at different times for each computer overnite to do incremental backup.  Thanks.

You can put the drive on on PC and use a router and sharing.
I would use Windows NT Backup.

I've never seen a router with an eSATA connection... I suppose they could have them... but not likely.  I'd suggest you connect it to one PC and share it.  That one PC can directly backup to it and the others can connect to the share and backup to that.

Though unless you have a gigabit network at home, the speeds you backup with will be SLOWER than USB.

You could always get a relatively cheap NAS (I don't normally recommend them, but in this case...)

Thanks lee...I should have clarified...yes the drive goes on a PC and the PCs go on the router or hub.

Some drives are route-able, but not most.

Thanks for the responses.  Hook up to one PC and network to the other two PC's. What is the limiting factor for transfer speed if all computers are eSata?  Network card, Cat 5 cable, router? What do I need to appreciate eSata transfer rates between computers? Each computer is hooked to the router to access broadband. Is it possible to use second network card in each computer and network via a hub for the backup?
