Use a USB Drive for System Backup and Restore

A backup image is a file that you can use to restore your Firebox back to a previous state.

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 backup image to a connected USB drive, you can choose whether to include the Fireware OS in the backup image. This allows you to restore the Fireware OS when you restore a backup image.

To complete the procedures in this topic, a USB drive must be connected to your Firebox.

This help topic describes how to use a USB drive for backup and restore in Fireware 12.3 and higher. If your Firebox runs a lower Fireware OS version, see the Fireware 12.1 Help.

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.

Backup images that include the Fireware OS can be 70 MB or larger. We recommend you use a USB drive that is large enough to store several backup images.

See Backup Images Stored on a Connected USB Drive

When a USB drive is connected to the Firebox, you can see a list of backup images stored on the USB drive in Fireware Web UI and Firebox System Manager.

The date and time stamp shown in the Date column for backup images saved to the USB drive is in UTC time, rather than the local time zone configured on the Firebox. In the Fireware Version column, backup images saved to the USB drive in Fireware 12.2 or lower show Unknown.

Save a Backup Image to a Connected USB Drive

Backup images are saved to the USB drive in the \sn\flash-images directory, where sn is the serial number of the Firebox.

Backup images are saved in .fxi file format and have a default file name of <system name>-<firebox model>-backup-<YYYY-MM-DD-HH-mm-SS>-<Fireware OS version>.<build>.fxi.

When you save a backup images to a USB drive, you can choose whether to include the Fireware OS in the backup image. Only backup images that include the Fireware OS can be used as the auto-restore backup image. For more information, see Automatically Restore a Backup Image from a USB Drive.

Restore a Backup Image from a Connected USB Drive

You can use Fireware Web UI or Firebox System Manager to restore a backup image to your Firebox from a connected USB drive.

If you restore a backup image that includes the Fireware OS, the Firebox is downgraded or upgraded to that Fireware OS version automatically as part of the restore process. The Firebox restarts automatically when the downgrade or upgrade is complete.

If you restore a backup image that does not include the Fireware OS, the backup image must have been saved from the same version of Fireware OS as the OS version currently installed on the Firebox. If the backup image was saved from a different Fireware OS version, you must first downgrade or upgrade the Firebox to the same OS version before you can restore the backup image.

Admin credentials are stored in the backup image file. Make sure that you know the admin passphrase at the time the backup image was created before you restore the backup. If you do not know the admin passphrase, you will not be able to log in to the Firebox after the backup image is restored.

Delete a Backup Image from a Connected USB Drive

You can delete backup images that you no longer need from the connected USB drive.
