    Hi,

    I am currently cloning a 790 GB partition. Drives are Samsung HD103UJ and HD103SJ, so pretty new and fast.

    The cloning speed is at 400MB/min. That means, it is not even at 7MB/s.
    Therefore the cloning of the entire partition takes 30 hours.

    File System: raw
    Block size: 512 byte

    Is there anything I did wrong? Could I have forgotten something?
    Would you have any links to a documention or FAQ, that could help me here?

    Thanks.

    I'd like to add: Under Windows, I get faster speeds too. Motherboard was bought last year:
    MSI P965 Neo2 FI

    It depends on the media where you save your image, too, and the compression program you choose (if you have chose that), and maybe more dependences. You did not mention how you save your image.

    Some people reported that they can save the image at the speed about 2 GB/min.

    BTW, unless your data is full of the disk (790GB), clonezilla will save only the used blocks.

    BTW, maybe give Clonezilla live 20090912-karmic a try. It comes with newer kernel, and supports multi-core compression.

    I started a partition clone from local disk to local disk. Entire partition.
    The partition is an encrypted truecrypt volume. So its full.
    I started in beginner mode.

    Is there any compression used in partition cloning? My thoughts are it would only be used in image creation.

    If it's an encrypted truecrypt volume, then Clonezilla should use dd to do a sector-by-sector copy. It's very inefficient, that's true.

    Steven.
