# export
```markdown
Usage: docker export [OPTIONS] CONTAINER
Export a container's filesystem as a tar archive
Options:
--help Print usage
-o, --output string Write to a file, instead of STDOUT
```
## Description
The `docker export` command does not export the contents of volumes associated
with the container. If a volume is mounted on top of an existing directory in
the container, `docker export` will export the contents of the *underlying*
directory, not the contents of the volume.
Refer to [Backup, restore, or migrate data volumes](https://docs.docker.com/v17.03/engine/tutorials/dockervolumes/#backup-restore-or-migrate-data-volumes)
in the user guide for examples on exporting data in a volume.
## Examples
Each of these commands has the same result.
```bash
$ docker export red_panda > latest.tar
```
```bash
$ docker export --output="latest.tar" red_panda
```
