"Normal" vs Schottky: which diode to use in a basic ...

Hello,
I still am kind of a noob in electronics, and I found out about schottky not that much time ago.
I'm creating a circuit with an MCP RTCC, connected to an UNO (test phase, later it will be connected to a tiny); to retain data I enabled its backup battery (standard 3.2V CR battery), putting a "normal" silicon diode between the battery and the component.
Everything works fine, but why not squeeze more?
I heard that Schottky diodes can have a very low voltage drop (thus ensuring that the battery backup can last longer). Are there any drawbacks of using a schottky?
Thanks
