Andrew has a point. dd is not a good choice. FS don't like it if some parts of |
| 31 |
them are in a different state than others. |

|
| 33 |
Also, with dd, everytime you restore, you also restore fragmentation - oh and |
| 34 |
a bigger partition? Can be tricky. |

There is nothing wrong with tar. In fact tar is great for this job. dd not. |
