[Q] Do a backup without root or recovery ?

Hi the community,



I had the HTC Desire Bravo during few years but have recently changed for a Z3C,



I saw the Andoid 5 update, but before updating I am wondering if it's possible to do like a nandroid backup / recovery backup without rooting the phone or something like that,

I do need my phone because I am oversea and don't want to take any risk at the moment,



I never had any problem with the HTC Desire Bravo while installing ROMS etc but for the Z3C I don't feel confident and really don't want to brick it,



Is Titanium Backup app or something like that could be good ? (I saw that for this app the phone has to be rooted...)



Thank you in advance for your answer,
