Our mobile phones contain important data such as phone numbers ,messages ,settings and applications. If our phone is destructed (may be software or hardware)any way we cant get these files. To avoid this data loss we should use the back up option provided in our phone.Many people does not use this facility .
Some times settings( Settings means GPRS settings or other phone settings) of our phone will loss and cause problems.
Ex: When you try to play a song the music player show out of memory. This problems can be simply solved by applying back up(.NBF )file.
Some times we want to restore our phone . Restoring will loss all data and settings. Some service providers will take more to send GPRS settings to our phone. If we store our previous GPRS settings then we can easily apply it.
STEPS for BACK UP
(Nokia phones)
Go to MENU-->Settings-->Sync and backup-->Create back up
This will create a .NBF file in your memory card. Store it in your computer for future use.
Note: I found that some Nokia phones shows music player problems( out of memory problems). If we apply .NBF file of another same type phone this problem will be solved.
