[BUG] Backup/recovery commands fail when executed directly after upgrade

[przemyslavic]

Describe the bug
Backup/recovery commands fail when executed directly after upgrade as there are no vars/specification generated.
It works fine when testing the following scenarios:

• apply->backup->recovery
  and
• apply->upgrade->re-apply->backup->recovery
  but fails when executing
• apply->upgrade->backup

How to reproduce
Steps to reproduce the behavior:

1. deploy any cluster < v1.3
2. upgrade to v1.3
3. execute epicli backup

Expected behavior
Backup/recovery should be successful or there should be an assertion to check if apply was executed first.

Config files

Environment

• Cloud provider: [all]
• OS: [all]

epicli version: all epicli versions

If you are using a module and expect the file to exist on the remote, see the remote_src option

One more information about backup/recovery. It should be run only after apply. So the correct paths are apply->backup->recovery and apply->upgrade->re-apply->backup->recovery. When executed directly after upgrade it will fail as there is no specification/vars. Do we accept this approach? otherwise we still have some work to do. Failed examples

The task includes an option with an undefined variable. The error was: {{ dirs_to_archive | default([])
                   | map('regex_replace', '//*$', '')
                   | select
                   | map('regex_replace', '$', '/')
                   | list }}: ['{{ component_vars.specification.storage.data_directory }}/snapshots/{{ prometheus_snapshot_name }}/']: 'dict object' has no attribute 'specification'
The error appears to be in '/shared/build/10to13awrhflannel/ansible/roles/backup/tasks/common/create_snapshot_archive.yml': line 28, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:

- name: Reconstruct the paths_to_archive list
