Simple compressed disk image backup?

[Mark Stier]

Hello,

I want to create a disk image of my notebook's 40 gig drive. First
problem: I cannot use partimage cause there is a large and compressed
NTFS partition on it. Second problem: the destination disk has about
35 gb free. Therefore I need compression.

I cannot use bzip2 since it is far too slow. But I also cannot use
gzip in the trivial "cat /dev/hda | gzip -9c > dest"-manner since gzip
does not accept more than 2 gigs of input. Therefore I need something
like "split" which chops the backup data into chunks and compresses
each chunk separately. Is there any possibility to do that? Of course,
it should support the reverse operation :-).

Second question: is there an utility to create and apply recovery
volumes or something similar in order to protect against bad sectors
(like rar does)? I have tried to use rar to backup /dev/hda, but the
checksums are broken.

Thanks in advance,
Mark

I think dd would do what you want,
