We create an LVM mirror which does the same as an LVM Raid1 which is it creates 2 (or more disks) with the same disk image. The advantage of having a mirror copy is that if one disk fails, processing can continue without needing to restore from a backup and losing everything that happened between the last backup and the disk failing.
