 **NVRAM** - (Non-volatile RAM) is used for storing the hardware's configuration. While loading the firmware from the squash filesystem, parameters in the form of variables are fetched from the NVRAM. NVRAM size is relatively small and is measured in Kilobytes (KB).

 The figures below represent an example of storage allocation (not to scale). The numbers will vary based on your FreshTomato version and your hardware specifications. See the [[:hardware_compatibility|Hardware Compatibility]] page for more information on specific FLASH and NVRAM specifications.

-**CAUTION**: As a safety precaution, FreshTomato will prevent you from performing firmware upgrades if a JFFS partition is mounted/in use. The reason for this is that if you were to disable JFFS and upgrade the FreshTomato firmware, you might lose the contents of the /jffs partition. For this reason, you should do a backup and restore operation to preserve the data there. To learn more about backup and restore of JFFS partition data, see the XXXX page.
