The Storage widget provides the ability to view system information including internal flash memory, CPU utilization, and log sizes, as well as to perform system and database backup and restore operations. It also provides the ability to change logging settings (data and/or event logging, and storing on an SD Card).

Warning: You cannot install a USB flash drive into a SmartServer with any USB network interfaces, such as the U60 FT network interface. As a result, you cannot use a USB flash drive for data log storage if you have any USB network interfaces attached to your SmartServer. Instead, use the SD Card for data log storage.
