In reply to Geoffroy. There's a reason why "dd" has been dubbed "disk destroyer."

Two interesting option :

status=progress - this gives progress status during the copy.
bs= 16K - fix the block size to 16 Kilobytes, this increases the speed (you can select other values but the default one is too small and reduces the bandwidth).

Well, after working for an hour or so – without error message – it bricked my system completely. Also the so much favored “Boot Repair Disk” made the catastrophe even worse. The problem seems the discrepancy of the sector size in both partitions.

Only my Windows System boots ok – but with mysterious error messages.

So this is not the solution to my problem. I can start from scratch now and install a new system.

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
