Hello Ivan, More detail is needed to properly start an investigation in this issue, especially in what concerns the ah-builtin-python-module. Do you mean ah-builtin-python-bundle?
How did you determine that the spinning up of new instances is caused by the backup jobs? Why would the algorithm leave some instances running for such an extended span of time, between successive backups? It would help a lot if we may become able to reproduce the issue locally, with a significant version of your app and your exact procedure for backup.
