Hi i wana know about VPS mirroring. During my research i found that "it involves 2 VPS's of the same configuration which are setup on such a way that if one of the VPS's fails due to some reason, the other VPS takes it's place ensuring 100% uptime guarantee to the websites hosted on the VPS's. The data on the first VPS is transferred on the second VPS at regular intervals so that if the first VPS fails due to some reason, the second one has all the data."

Can anybody please explain more about VPS mirroring? Thanks
