keep windows from entering standby/hibernation during transfers

[klaernie]

First of all: thanks for packaging rsync ready to use, makes my life much easier.

I am running rsync on the family PCs around, but some long backups abort since the PCs enter sleep before completing the backup. So I was wondering if there is a way to keep windows from entering standby or hibernation while transfers are happening.

Looking around I found the cygwin nosleep package, which uses Windows' API to set the power requirements for the thread (https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-setthreadexecutionstate).

According to Microsoft's documentation:

To run properly on a power-managed computer, applications such as fax servers, answering machines, backup agents, and network management applications must use both ES_SYSTEM_REQUIRED and ES_CONTINUOUS when they process events.

Would you think this could be patched into rsync, so that it prevents the PC from sleeping while a client is connected?
