Remove local backup after upload to S3

[Kavan72]

I've configured the backup of my PostgreSQL Docker instance, where I've set it to take a backup from the last month and upload it to S3. Now, all these backups are also present in the local file system. Is there any way to remove them after uploading to S3?

Unless you have also configured a local storage backend, the in-container archive files will be deleted after upload. What makes you think they persist locally? Could you share your configuration?

here is my configured file

services:
  backup:
    image: offen/docker-volume-backup:${DOCKER_VOLUME_BACKUP__DOCKER_IMAGE_VERSION}
    restart: always
    environment:
      # Take a backup on every n

By mounting your local path to /archive , you configure a local storage backend: https://offen.github.io/docker-volume-backup/reference/ thus files are persisted by design.

If you don't want to keep local backups, remove the mount.
