For some reason we can't back up all the partitions in nandroid. It should be enough to backup system and data. Optional: boot, logo (if you modified M boot logo), cache (usually not necessary), sd data (if you use ext partition on SD card).
With nandroid of system and data (and the others, but only if you use them) you should expect to be able to go back to exactly how your phone was at the time you made the backup. But you will lose changes you made after you made the backups.
When I'm about to start testing ROMs, I backup system and data. To go back to my pre-testing ROM I restore system and data and then wipe cache partition.

You want to say system and boot ?
Because changing a room modify system.img and boot.img
The boot.img is the same on all the ROMs thanks to the locked bootloader.
Yeah, I never even bother changing boot.img from the sbf version. If I did I'd probably use the Russian one because I think it was the most recently compiled.
Ok, I wasn't knowing that I always flash boot.img that come with ROM.
I've made a backup using stock recovery. But I am unable to restore it due to checksum error. Now that I've installed CWM, it doesn't shows that backup file. Is there any way I can have a restore of the my original .backup file?
Hello guys. Is it necessary to change data file system back to f2fs before restoring?
Restoring what, a backup of stock rom by what i assume? If you went of custom, and now you're coming back to stock yes, you gotta restore data partition to f2fs before restore a backup. If not, it won't work.
Can someone list the partitions necessary for a full save? Is system/boot/data sufficient?
So it seems that the current version of TWRP fails when backing up /system due to the vendor folders. The solution is to backup boot, system image and vendor image, which also preserve dm-verity (whatever tf that is).
I am a newbie!
So I wanted to start flashing custom ROMS on my device...
So I flashed the Custom Recovery(TWRP) and downloaded compatible Custom ROM...
Ok so by following some blogs and videos I took the system backup of boot, system.
And yes I am able to restore it...
I also read about Android Partitions(https://forum.xda-developers.com/general/general/android-partitions-explained-t3657183)
But when taking the Backup I saw a System Image partition there.
So I am wondering what is its use and should I backup that for pure Stock ROM Backup?
And also does it include the boot partition files or I also need to backup the boot partition with it?
And if I create this file using which option can I install this type of Backup?
Thanks in Advance

It isnt complicated, just boot into TWRP, then choose the "Backup" option, the default partitions that TWRP automatically selects to backup are all you "need" to backup. TWRP backs up the boot partition, recovery partition and system partition by default, that is all you need.
To restore the backup, just boot into TWRP then select the "Restore" option, then restore the backup file.
The "system.img" backup creates a backup of the complete system.img, it is effectively the same thing as using adb shell to dump the system.img to obtain a copy, it contains everything involved with the system partition, including boot.img and kernel(zimage). This system.img backup can restored by using fastboot flash system command, adb shell with dd command, terminal emulator with dd command or by using the option in TWRP that allows flashing .img files.
Another option for devices that are rooted is to use apps like Flashify to flash the system.img, but these apps are risky and don't always flash correctly.

Thank You Bro So Much for explaining this:laugh:
Ok So I can keep the backup of the system image if I want a complete stock rom backup, right?
But what about the other partitions like Recovery, IMEI, FRP, Pinfo, Logo?
I mean to say if I clear all these partitions for eg IMEI, will my device's IMEI number be deleted?
Or after flashing the system img these partitons will be regenerated?
And yes I am using the default TWRP backup and I am able to restore my android backup...

The default TWRP backup is all you really need. It will completely backup everything you need to backup/restore your ROM, the system.img backup isn't necessary. It is no different than the system.img that can be extracted from your stock firmware file.
As for IMEI, the method of backing up and restoring IMEI doesn't involve TWRP, there are other tools for that. Do a Google search for:
"How to backup and restore IMEI"
I suggest that you don't mess with any of the other partitions
