I have just installed Windows 7 and now my computer won't wake from hibernate for nightly backups from Windows Home Server. As soon as I turn it on the morning it will backup then. It was running with no problems on Vista and I haven't changed any other settings in the bios and things. I found on the network adapter in bios that there was an option to allow this device to wake the computer, I have checked that but it still won't wake. Is there anything that I can do? I have seen other questions similar to this on here but non had a useful answer.

This will be patched in WHS powerpack 3, out in 14th December, according to the release notes. You may be able to get the Beta still, which solves the problem - see here:

Windows 7 client PCs will not automatically wake up to do a backup: Windows 7 users can work around this by doing manual backups, or also by turning on the wakeup timer in the Windows client Control Panel. Power Pack 3 beta also fixes this issue.

No Sleep "is a command line tool that disables sleep or hibernate, runs a batch file or program and then enables sleep or hibernate again. It will run on any recent version of Windows."

Haven't tried it myself- yet. But I'll use it to enable my morning alarm.

See this article:
Wake up your computer from standby or hibernation, perform an action, and send it back. Automatically.

It describes a freeware named WakeUpFromStandby, available for Vista (which might still work on Windows 7):

Can restore almost every Windows-based operating system from a Stand-by mode (and some from hibernation) that support ACPI (Advanced Configuration and Power Interface) (For support check computer's BIOS as well as Control Panel -> Power Options);
