Where does my snapshot go (found it, but how to solve this in docker)

I created this automation. I don’t get any errors and the automation is triggered every minute.
However, In the expected folder /www/media/ no snapshot can be found.

id: '1641738510337'
alias: snaphot from camera
description: ''
trigger:
  - platform: time_pattern
    minutes: '*'
condition:
  - condition: time
    after: '07:00:00'
    before: '18:00:00'
action:
  - service: camera.snapshot
    target:
      entity_id: camera.babycam
    data:
      filename: local/media/achtertuin_{{     now().strftime("%Y%m%d-%H%M%S") }}.jpg
mode: single

In the logging I can see that a correct filename was made.

Well I found the files :slight_smile: But not at the place I want them to be. I am using docker on a synology nas.
I found the files in :/volume1/@docker/btrfs/subvolumes/6212fa207235480bb3784820d54dc7d7a8dc1ae10e0e41dee650a578c9d46014/media/
I want the files in a subfolder under my configuartion file.
Can anyone tell me how to change the filename in the automation ?

I know this is more a docker-thing but I hope some can help me with this.
