 In addition to storing data using Azure storage services or in your device's container storage, you can also dedicate storage on the host IoT Edge device itself for improved reliability, especially when operating offline.
 
-To set up storage on the host system, create environment variables for the IoT Edge hub and IoT Edge agent that point to a storage folder in the container. Then, use the create options to bind that storage folder to a folder on the host machine.

 1. For both IoT Edge hub and IoT Edge agent, add an environment variable called **storageFolder** that points to a directory in the module.

 For example, on a Linux system, `"Binds":["/etc/iotedge/storage/:/iotedge/storage/"]` means the directory **/etc/iotedge/storage** on your host system is mapped to the directory **/iotedge/storage/** in the container. On a Windows system, as another example, `"Binds":["C:\\temp:C:\\contemp"]` means the directory **C:\\temp** on your host system is mapped to the directory **C:\\contemp** in the container.
 
-Additionally, on Linux devices, make sure that the user profile for your module has the required read, write, and execute permissions to the host system directory. For example, if you wanted to enable the IoT Edge hub to store messages in your device's local storage and retrieve them later, you need to grant these permissions to its user profile, UID 1000. (The IoT Edge agent operates as root, so it doesn't need additional permissions.) There are several ways to manage directory permissions on Linux systems, including using `chown` to change the directory owner and then `chmod` to change the permissions, such as:
