I have thought about this. I Pine for this
You are **spot** on!
1) either my hands are tied
2) or, I am running VEB on Server 2008 R2 [i.e. based on Win7]
If anyone is curious, I buried my netsh script idea. I need VEB to keep my bacon safe, and I need some installations to be mobile. The best solution for mobile is disable schedule (within VEB) and rely entirely on "Task Scheduler" command line task. Then I keep Task Scheduler open (minimized) and manually disable scheduled task when I go on WiFi.... and hopefully I remember to re-enable when I reconnect to wired.
I do not love this manual process. But I cannot torture either my mobile device or our wireless network trying to backup if I am wireless at the same time the backup is scheduled to run.
It is manageable for this user.... your results will vary depending upon your end user
