Nandbackup on pendrive - is it possible?

Hello,

I'm thinking on exchanging my S5 for S6. Very often (not immediately) I mod my smartphones.
My question is there is a recovery that will allow me to do backup on pendrive?

I'm thinking about Dual Pendrive like this:

¿Can I install apps in a pendrive?

Hello
Can I install apps in a pendrive with a pendrive connected to a cable Usb otg?

P.D:I don´t have root and I don´t want to do it.:laugh:
