## Description
Produces a tarred repository to the standard output stream.
Contains all parent layers, and all tags + versions, or specified `repo:tag`, for
each argument provided.
## Examples
### Create a backup that can then be used with `docker load`.
```console
$ docker save busybox > busybox.tar
$ ls -sh busybox.tar
2.7M busybox.tar
$ docker save --output busybox.tar busybox
$ ls -sh busybox.tar
2.7M busybox.tar
$ docker save -o fedora-all.tar fedora
$ docker save -o fedora-latest.tar fedora:latest
```
### Save an image to a tar.gz file using gzip
You can use gzip to save the image file and make the backup smaller.
```console
$ docker save myimage:latest | gzip > myimage_latest.tar.gz
```
### Cherry-pick particular tags
You can even cherry-pick particular tags of an image repository.
```console
$ docker save -o ubuntu.tar ubuntu:lucid ubuntu:saucy
```
