Use a USB Drive for System Backup and Restore
An backup image is an encrypted and saved copy of the flash disk image from the Firebox flash disk. It includes the device OS, configuration file, feature keys, Device Management users, passphrases, DHCP leases, and certificates.
You can attach a USB drive or storage device to the USB port on the Firebox for system backup and restore procedures. When you save a system backup image to a connected USB drive, you can restore your device to a known state more quickly.
The date and time stamp for each saved backup image is in UTC time, rather than the local time zone configured on the Firebox.
About the USB Drive
The USB drive must be formatted with the FAT or FAT32 file system. If the USB drive has more than one partition, Fireware only uses the first partition. Each system backup image can be 70 MB or larger. We recommend you use a USB drive large enough to store several backup images.
