Internal backups can be completed automatically or manually. Use the Auto NVM Backup screen in CDFT-E to configure automatic backups. NOTE: Enable Automatic Backup must be checked in CDFT-E for automatic backups to occur. A weekly interval is the default setting for automatic backups. External backup The external NVM backup can be used to manually transfer the existing system image to a specific external backup destination. You can use CDFT to perform an external NVM backup. NOTE: A backup using CDFT-E is usually performed to back up the image to a USB mass storage device such as a thumb drive. To perform NVM backups using CDFT, see Manage non-volatile memory (NVM) on page 56. NVM restore Use CDFT to restore NVM for the entire system or for a specific subsystem from an external or internal source. NOTE: You can only restore NVM data to the MFP that was the source of the backup. 108 Chapter 4 Managing and maintenance ENWW
