How to make a disk mirror with different HDDs Ubuntu Server?

SSD 128Gb - there is an ubuntu server with data.
HDD 1Tb - new, empty.
Is it possible to make a software raid so that the second screw has a mirror of the first screw, and the remaining partition can be used as storage?
So that if the ssd fails, you can urgently start from the second screw.
Nuance, the system is working and the data is needed. As far as I remember, when creating a raid, infa is destroyed on both. Then maybe there is a simple synchronization?
Thanks in advance for your help.
