    Are you referring dd related to OS disk ? dd is mostly used to copy data (disk dump) from one disk to another as cp is not copying entire data completely.

    In case of physical servers mostly H/W raids are configured as RAID 1 for OS. For data volumes if required you can create mirrored volume in LVM or if you are using Veritas you can create desired RAID.

    Rsync will be good option as it is also used as data replication across site as well as locally .

    Cheers

    The big problem with dd is that if an error is found, when it is cloning, it stops. But this can be avoided adding: conv=sync,noerror
