I want to do a nandroid backup of my Lenovo a7000 phone running android 5.0. I only want backup of internal phone system, not the SD card backups. That is to say, whenever I restore the backup, I should have all the installed apps as it is and my phone settings intact. What is the most appropriate way to do it? I have cwm installed and read about taking backup from cwm. Is there any way to know about the estimate size of the nandroid backup so that I will free up space on my sd card accordingly?

If you're just asking about how to estimate the size of the Nandroid backup, then you can issue a "df" command from and adb shell or Android Terminal Emulator app.
That "df" (disk free) command will show you a "Size" column for each filesystem. The ones that you would typically backup in a custom recovery would be /system, /boot (won't be shown), /cache (optionally backed-up), and /data.
The boot partition won't be shown by "df" however--but relatively speaking, it's not a large partition compared to the others.
The /data partition would be backed-up minus the /data/media portion if your device is using an "internal SD card". If you've got a external card and your /sdcard is truly separate, then this will indeed be the size of the /data partition that would get backed-up.
For example, here's my Nexus 5:
Microsoft Windows [Version 6.1.7601]

My N5 doesn't have an external SD card, so to figure-out the space used by my "internal SD card" I did this:
So you can see that almost 9Gb of the 12.6Gb reported for my /data partition is actually being used for the internal SD card.
Hope that helps!
