### Create a backup that can then be used with `docker load`.
|
|
|
|
```bash
|
|
$ 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

|
|
|
```bash
|
|
docker save myimage:latest | gzip > myimage_latest.tar.gz
|
|
```
|
