## Using Partclone with an ext4-formatted partition

### Without compression

To backup *without* compression:

```
$ partclone.ext4 -c -s /dev/sda1 -o ~/image_sda1.pcl

```

To restore it:

```
$ partclone.ext4 -r -s ~/image_sda1.pcl -o /dev/sda1

```

### With compression

To backup *with* compression:

```
$ partclone.ext4 -c -s /dev/sda1 | gzip -c > ~/image_sda1.pcl.gz

```

**Note:** For maximum compression use "gzip -c9"

To restore it:

```
zcat ~/image_sda1.pcl.gz | partclone.ext4 -r -o /dev/sda1

```
