Restoring an ansible backup file

[Tony Owens]

I'm trying to copy a file out with backup option which works fine.  I'm pretty sure I am overlooking over something simple here.  Any help is appreciated.

For starter you shouldn't use the developer list for user questions

If you check the return values for the copy module you'll see it return backup_file
https://docs.ansible.com/ansible/2.6/modules/copy_module.html#return-values

So add «register: result» then you'll have the filename in {{ result.backup_file }}, this might be easier.

src doesn't take a list so you need to choose one of the element in the list, to take the first you need
src: "{{(myfile.files|map(attribute='path')|list)[0]}}"

But remember, you might have multiple backups on the same day and find will return them all so you never now which one is in the first element.
