I want to make a full backup of the memory card (MicroSDHC) of my phone (a Nokia N82), on which applications are installed, just in case I have a problem and have to format the memory card (as it actually happened some times ago

So, will it be possible with USB Image Tool to make such a backup, which I can restore, even on a different (even if of the same size) memory card?
If I just copy and paste all the files from a memory card to another one, if I'm not wrong, the phone should recognize a different memory card and applications for some reason won't work
So, a "device mode" backup will work, if restored on a different memory card?
Many thanks for your help!
