docker exec -it backup rclone-config
# run an initial full backup
docker exec backup dup-full
# verify backup files
docker exec backup dup-verify
# list backup files
docker exec backup dup-list
# restore a file or directory
# .. restored file or directory will be put in the /restore volume
docker exec backup dup-restore-file /path/to/file/or/directory
