Re: How to backup an HFS+ filesystem ?

Hi,

I would like to known if the dump command is aware of the metadata of HFS+
or if it's dealing only with the flat files ?

dump on most Unices bypasses the filesystem code in the kernel and reads the
raw device directly, and Darwin does not appear to differ. Without looking at
the source, I believe Darwin dump only understands UFS...

# dump -0f /dev/null /dev/rdisk0s9
DUMP: Date of this level 0 dump: Sun Sep 22 12:36:01 2002
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rdisk0s9 to /dev/null
DUMP: bad sblock magic number
DUMP: The ENTIRE dump is aborted.

Otherwise do you know guys a good tool to backup HFS+ (beside Retrospec of
course).

I'm quite partial to TSM from my work perspective, but I have a feeling that
that may be a little out of your reach (and the Mac OS X implementation has
some limitations).

Try hfspax, written by Howard Oakley <http://homepage.mac.com/howardoakley/>.
It backs up both forks, and the finfo structures. BTW, it does use Carbon
routines, so won't work on native Darwin, you need Mac OS X.
