Thanks for the suggestion waveweaver, pardon this question from an inexperienced (<2 week android, <1 week root experience) user but when you mention CWM recovery, i assume it has already been installed into my phone when i rooted it even though i can only see CWM and SuperSU icon in my apps. I assume i can enter the recovery either via the CWM manager or the triple button combination on phone. Does the choice of backup appear in the recovery mode or is it an apk app that i activate similar to all programs e.g. ROM manager and it will self boot and self backup after that?
Strangely when i try to use the CWM, it says "This version of CWM Manager should be used with CF-CWM v1.1 or newer. It appears you are running a different recovery. Various features have been disabled". Umm, i am in need of a dictionary to explain this. Does this mean i have to re-flash again? I used the Odin method of rooting my phone last week.

Thanks again.

Ignore the error.....The backup and restore can be access via the 3 button mode...

Do you using custom kernel.? And did you root your phone by flashing CF-root.?
Anyway if you use custom kernel the then CWM Manager app will be disable much of its feature. That's okay as you can still go into CWM recovery by using three buttons combo and still can do Nandroid backup.

One more thing..CWM Manager app is NOT compatible with ROM Manager app.

Which CWM version? maybe you can get cf root 6.4 and try root again.

Backup restore shoudl be there...

~~@ wynx
Are you sure your CWM recovery dont have 'backup and retore' in it..? Is it CWM recovery or stock 3e recovery.?
Hmm..i suggest you try root again your phone using PC Odin using CF-root from the link below

Thanks waveweaver, will re-root again, I havent found my previous files yet. Haha.
You are right, it is stock 3e recovery. What does that mean?

Hmm will S3 get all the feature that is available in Galaxy Note 2 in JB FW?

why Asphalt 7 and The Dark Knight Rises cannot ply on my S3. every time i enter is write "unfortunately, asphalt 7 has stopped. Anyone can tell me how to solve this?

It means most probably your phone got root but not CWM recovery. Since you got root edi then you can just flash the CWM zip files via PC Odin to get the CWM.
Below is the link for CWM zip files. You can use either way
