CX4-240 Configuration Backup

Hi,

I am a newbie on storage systems so please be patient with my questions if they sound too easy

We have a CX4-240 system and we lost one hard drive (one from those that keep the configuration stored on them).

Question 1: Is the configuration in any kind of "danger" if i just replace the HDD (anything i need to know before i replace it etc)

Question 2: What is the way/ways to backup the configuration of the specific storage?

Thanks in advance for your time,

Charis
