I have clone NTFS Partition for how many years, but Ext Partition of Linux not ever since. To those who have experience with this, any comment either bad or good.
It should, I never tried Norton Ghost, but acronis true image succeeded to clone an HFS partition This is because both programs read the disk bit-to-bit
Linux has some tools builtin to do that, no need for NortonGhost.
Now you can work with the files again. Actually that works regardless of the file system, be it NTFS, HFS, UFS, ext, xfs, zfs...
The drawback however is that you will need just as much space as the original partition needed, neither compression is done nor does dd have any knowledge about which blocks are allocated by the filesystem, so dd just grabs the whole partition.
Another approach may be rsync which allows you to migrate on the fly, afaik it will take care of ACLs given the file system is supported and you use the proper options.
Linux is not Windows - just because you are used to working with Windows tool doesn't mean it is a good way to do it on Linux, as compression goes you could pipe dd thru gzip, bzip2 or some compression tool you like to save some space, you will however looese the ability to loopback mount the image.
The answer to your question is yes, Ghost can deal with ext3 partitions, although it may not be as fast or (if you are taking the image to another computer) as space-efficient as it is with NTFS.
