AFAIK there is nothing exactly like Ghost for Linux, at least not yet.
Last I checked there were some alpha projects. They could me more
mature by now...
The dd command can copy an entire hard drive or a single partition
byte for byte. It's not as flexable as ghost however. It knows nothing
about the size or partitioning of the hard drive and will also copy
all of the empty blocks, so you can only restore a dd image to a
drive/partition of the same or larger size, and if it's larger you
will not be able to access the extra space.
dd if=/dev/hda of=hdaimage bs=10M
This will create an image of the entire hda drive including all
partitions in the file hdaimage in the current directory (don't create
this file on hda obviously). The bs makes dd copy 10 meg chunks at a
time, greatly speeding up the copy.
dd if=/dev/hda1 of=hda1image bs=10M
This will create an image of just the first partition on hda. man dd
for more info.
Tar works perfectly for copying a single partition. It captures all of
the file system metadata. If you are using SE Linux you need to make
sure you are using a version of Tar that captures SE Linux info and
you may need to pass a command line switch to turn it on. Of course if
you are trying to restore a system from tarballs you will have to
partition and format by hand first and then restore each tarball for
each partition.
I'm confused about tarring /dev. It used to be that /dev was a normal
folder with normal files. Then came devfs and now udev. I think some
of the files in /dev are created at boot by the kernel and maybe some
are real or something, I'm not sure.
