can back more partitions ignore the partitions that say zero i think i need to fix those. i also fixed where system was listed 2 times u can backup and restore other partitions if u want to or feel the need too https://drive.google.com/open?id=0Bx88t3CJrNjoQjhFQXBqSm0zRUk@yuweng guess he accidental added extra system to backup

The extra System your referring too is a System.img it's flashable with fastboot unlike the regular system backup in TWRP.
If you look at the file size you would notice the System.img is the same size as if you dd dump system
it also backs up cust.img and tz.img and modem1.img, it's by design not a mistake

On most devices shipping with Android 6.0 or higher, the device maker has enabled dm-verity as a security measure. The device will signature check blocks of data on the system partition during boot at the block level. The usage of dm-verity prevents TWRP from being able to successfully restore a normal system backup. On most of these devices, you will see an option on the backup page for System Image. A system image backup takes up more space than a regular system backup, but the system image backup is a bit-perfect backup that, when restored, will not break dm-verity (assuming that you don't break dm-verity before making the backup). On a handful of devices, you may also find a Vendor and Vendor Image backup option. The same rules apply with regards to dm-verity. If you need a perfect "go back to completely stock" backup then you should be using System Image (and Vendor Image, when available) instead of just system.
