I want to run a fully redundant failover environment in Azure. I have my webapps covered with an Azure Traffic Manager. I can run my storage queues in two different accounts. All is covered. The only thing I can't figure out is how timetriggers should be handled? I can't have them fire in both regions. Does anyone here have an idea or solution I could try?

Good question, I'm not aware of anything Azure does to support this. How often does the timer trigger fire?

I got like 6 different triggers that initiate import of data so I would like to have them only trigger once.

Please see the post - stackoverflow.com/questions/56383684/…

@SillyJohn thanks. This could be the answer even though this is not a pure solution because you need a third region with an account. But it is better than all the hacks I have thought about.

Time triggers will run only instance at a time even though you have configured for multiple instances scale out. The timer trigger uses a storage lock to ensure that there is only one timer instance when a function app scales out to multiple instances. If two function apps share the same identifying configuration and each uses a timer trigger, only one timer runs.
