# NAS

By default images are stored on the SD card of the Raspberry Pi, in the folder /etc/opt/kerberosio/capture. However it's also possible to store the images directly on a NAS (e.g. WD MyBook). To achieve this, you will need to do some minimal modifications.

## Let's get started

You will need to mount the NAS to the filesystem of your Rapsberry Pi. In order to make a permanent mount you need to edit the fstab file. The approach for KiOS is slightly different.

### KiOS

Before you can add your NAS to KiOS, you will need to modify the /data/etc/os.conf file. By default the root partition is read-only, therefore you will need to change it to read-write. To do this you will need to activate os_debug option.

os_debug="true"


After you've changed the value to true, you need to reboot the system. You will see see that the root partition is now writeable, and you're able to modify the fstab file.

nano /etc/fstab


//ip_address_to_your_nas/directory_on_your_nas /data/machinery/capture cifs username=user_on_your_nas,password=password_for_your_nas,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0


Mount the NAS

mount -a


Check if the mount was successful, you should see the already existing content on your referred NAS directory.

cd /data/machinery/capture && ls -l


### Other

nano /etc/fstab


//ip_address_to_your_nas/directory_on_your_nas /etc/opt/kerberosio/capture cifs username=user_on_your_nas,password=password_for_your_nas,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0


Mount the NAS

mount -a


Check if the mount was successful, you should see the already existing content on your referred NAS directory.

cd /etc/opt/kerberosio/capture && ls -l


And that's it. From now the machinery will store the images directly on your NAS, and the web interface will visualize them.
