Nitrality backup location

What is the Nitrality backup location?
I know where it is now but i do not see efs backup there
does it mean so it does not do efs backup?
OK now i know ti all but also kno that it does not do a backup of EFS partition just a files. The question is if there is a program that makes full backup of EFS partition and can recreate it when it is corupted?

[Q] Pretty sure my EFS partition is pooched, restore w/o backup?

So pretty sure I've lost my EFS partition or some of it's data, don't have a backup (yay me!), have tried odin flash to stock and doesn't fix...or I'm missing something...Thanks.

is backing up of EFS partition the same as backing up QFS

i saw that we should backup EFS when flashing , but i also read that some people backup QFS so as not to lose IMEI, should i do both? or should i simply backup the EFS partition , any advice please
hold efs partition backup should be enough, if you keep both also fine. personally i keep efs backup only and never use it due to when i lost my imei, i only need to flash some modem files
flashing modem files fixes your IMEI issues?

Redmi Note 2 QCOM(dior) data partition corrupted, how can I fix this?

Hello everyone!
I tried installing the latest fastboot ROM on a RN2 QCOM, and MiFlash fails with an error that it is unable to format a partition.
After booting into TWRP, I see that /data partition says size is 0MB, usage and free space also 0MB and it is unable to mount it. The other partitions are fine(though I can't find the EFS partition for the IMEI files). Previously running Hexagon ROM and TWRP 3020.
Is this is a flash storage issue or can I somehow reformat/fix it? Any help regarding partitioning and backing up my IMEI somehow would be highly appreciated!
Thank you
There is no Qualcomm variant of the Redmi Note 2 and "dior" is the Redmi Note 1.
