# Rapid Backup Unit

The Rapid Backup Unit (RBU) has the form factor of an SD card. The RBU contains all the current network configurations and settings. During the installation and configuration some of the parameters are saved on the card. In case of a failure, it is a quick task to remove the card and put it into a new tool and all functionality remains the same.

When the RBU is transferred from one tool to another, the new tool will be updated to the software on the card. Since there is a chance of loss of data during the update procedure, it is good practice to make sure the new tool is already running the same software version as the old tool, to minimize the risk of data loss.

This RBU can not be used for anything but storing the tool configuration data and software. Reformatting the card, as well as manipulating the data on the card through other means than ToolsTalk Service 2, will result in an unusable card.

Note that the saved results associated with the tool will be lost when the RBU is transferred to another tool.

The MAC-address is associated with the RBU, not with the tool itself. When transferring a card to a new tool, the tool's MAC-address will therefore be the RBU's MAC-address.
