I realize this is a very late reply to this question. I just picked up a Doogee X5 myself and wanted to take a moment to address this question so as to inform any members who may have similar inquiries. Making a TWRP backup of System-Image creates a full and complete backup of the entire /system partition, whereas backing up System makes a full backup of all data written to the /system partition. For all intents and purposes, whether you choose System or System-Image, the entire Android OS is being backed up, so you are covered on either option. A full and comprehensive backup should also include your /boot and /recovery partitions as well. The /uboot option backs up your bootloader partition. The nvdata option safely backs up your unique device identifiers such as MAC address, IMEI, ESN, etc. This is closely akin to making an EFS backup on a Samsung device. Making a backup of /cache is typically never necessary unless you are wanting to restore your device to its exact state at the time of backup.
