flyctl regions backup does not work with [processes]

I ran fly regions add lax --group rails. It worked.

Thinking that meant the regions command supports groups, I then ran:

❯ fly regions backup lax --group rails
Error: unknown flag: --group


Backup regions probably won’t behave how you expect with multiple processes. If you’re able to run your app in multiple regions, you can avoid using backup regions altogether.

Thanks for the warning. The entire reason I was trying to use fly regions is because one process was fully ignoring the region list, and constantly starting in a new random region hundreds of milliseconds away from my data stores and the other process.

In the end, I had to create an empty volume and attach it to the second process before it would actually run in the region listed for that group.
