Aura is like energy. It's energy that protects you.. it can be recovered after given time.. and it can be expended towards semblances. Once you're out of energy, you're weak and vulnerable to damage.

In RWBY: Grimm Eclipse, Aura can be regenerated after about 4 seconds. In an rp... I would probably extend that time to something a little more realistic. To however long you think it takes to recover after sprinting for a mile.
