[usmann090]

I have read that u should make EFS backup.
As it contains sensitive information of your phone.
So,I have make efs backup using this application.EFS Manager.
The file is saved in.tar.gz format.
Now , I wanna know if anytime I need to restore my efs backup.
I just wanna know is that fine ? Or I need to do that in some other way ?
Thank you

I think it's prudent to backup your EFS partition if you can, but it's probably (and hopefully) very unlikely that you'll ever need to restore it (i.e., something very bad would have to happen to your device before you would need to restore it).

So, make a backup of it and put it somewhere off of your device for safekeeping .

If you've rooted your device then you should have a custom recovery e.g. TWRP or ClockWorkMod installed. These will optionally include the /efs partition in their nandroid backups, and allow restoration if required.

On my Nexus 5, I get the option to also backup the EFS partition from TWRP's backup:

I don't know for sure that TWRP is able to identify the EFS partition(s) for all devices--they're not always named "EFS".

You can backup and restore these partitions manually via the dd utility, but you'll need both a shell prompt from custom recovery and to know for sure what the EFS partitions are named (device-dependent).

I'm guessing some of the EFS backup apps might have an option to create a flashable .zip file to use to restore with, but I don't know for sure about that (you'll have to do that research).

You use the same program to restore that you use to make the backup. I use both QPST and NV Reader/Writer. Both are pc programs and backup is saved to pc. Just put them in a folder that you can find if you need it. Some Samsung devices, S3 in particular, can dump the EFS data if you do a lot of flashing. No fun trying to restore your IMEI number without a backup .

I have dont it with ES File explorer on my phone.
The files are backed up in .tar.gz format.
Is thta okay ?

Should be ok. I like making several using different methods incase one way fails when you try to restore,you have another to try. You can never have to many backups

+1 to all that great advice! My recommendation (short of TWRP EFS backup/restore) would be to dd write them back to the device after you get it back into a functioning state with root. You'll have the necessary file(s) to do so within your tar.gz.
