Auto Save in case of crash

Hi,

Let's say that we are using an interface and this interface crashed : our client faced an issue with emails and phone numbers being all messed up following this crash.

Does Hcm provide regular data auto-save / back up, can we ask to have a data back up that we had before the crash happened ? Can we configure/set up regular back up of the systems ? And what would be the procedure to have access to this back up ? How long would it take ?

Thanks for your help :)
