It may be worth your while looking at partimage (which can also image |
| 10 |
whole drives). It only copies used sectors so avoids the problem of |
| 11 |
storing obsolete data. I believe Clonezilla uses partimage, and you'd |
| 12 |
have to use a live CD to image a system drive like this anyway. |
