For mirroring to happen on a schedule:

docker run -e MC_SOURCE_EP_ACCESS_KEY=<Access Key> -e MC_SOURCE_EP_SECRET_KEY=<Secret Key> -e MC_SOURCE_EP_HOST=https://<YOUR-S3-ENDPOINT> -e MC_DEST_EP_ACCESS_KEY=<Access Key> -e MC_DEST_EP_SECRET_KEY=<Secret Key> -e MC_DEST_EP_HOST=https://<YOUR-S3-ENDPOINT> -e CRON_EXPRESSION="0 * * * *" salvoxia/minio-backup-s3:<IMAGE_VERSION>
