How to Fix - Central Backup device unavailable to other computers when main computer is asleep?

Central Backup device unavailable to other computers when main computer is asleep

I have a mixed network of 5 computers: 2 running Windows 7, 2 running Windows vista, and 1 running Windows XP.
I have a large external hard drive connected to my main Windows 7 machine, and shared on the network for backup purposes.
The XP Machine and
one vista machine use OneCare to do backups, but often cannot do the backup in the nighttime because the windows 7 machine with the external drive connected to it goes to sleep, and the drive is then not visible to the other computers.
I would like the external
drive to always be visible and available on the network, but I don't want to completely disable sleeping on the windows 7 machine (not to mention that I'm not sure how to completely disable sleeping anyway).
Would someone help me with some ideas here? If the
only option is completely turning off sleeping, then that's what I'll do.
Thanks.

I have other computers backing up to my Windows 7 computer.  There is the POWERCFG command line utility.  Open a command prompt and type "POWERCFG /?" to get instructions, particularly for the -LIST and -SETACTIVE options.  Open "Choose a power plan." 
Watch how POWERCFG -SETACTIVE commainds in Command Prompt make the radio buttons move in Choose a power plan.

I created custom power plan that has: monitor off 5 min, computer off 1 hour.

I have a Task Scheduler task that starts my custom plan at 2:55 AM daily with the "Condidtion" to "Wake the computer to run this task."  My other computers start backing up to this box at 3:00 AM.  The network activity keeps the Windows 7 computer awake.
I have another Task Scheduler task that sets my computer back to the "Balanced" power plan at 4:00 AM.

HTH  (sorry I don't have time to be more detailed)
