I am very new to dedicated servers and just found out that it is good to have a mirror even if you have a backup drive as mirror is completely different from backup... is it 100% recommended to have a RAID on the server or can one do without it?

RAID (Redundant Array of Independent Disks) is used to either speed up access to the data or prevent loss of data if one of your hard drives fails. RAID 1 is mirroring where one or more disks are mirrored to another set of identical disks. If you set up two disks in a RAID 1 configuration and one of the dries fails the other drive takes over as the primary and you replace the defective drive and the system automatically re-mirrors the new drive. Look at this web sie for a better description:


You need to have the Mirror RAID. It's really useful when server gets hacked and all the files are lost. You can recover real quick with it.
