The problem I have specifically with rsync (or tar, or cp) is that
it does not save ACLs, file attributes too well, and so on that I
gave up using it. Perhaps the problem in this case is not to use
the -a option but to use the manual options to save everything
about the files that you can.
Specifically:
rsync manual:
-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
-H, --hard-links preserve hard links
-A, --acls preserve ACLs (implies -p)
-X, --xattrs preserve extended attributes
Do you mean that you've tried these (particularly -A and -X) and they
don't work? If so, have you filed a bug report?
I am not certain that it's a bug per-se, it's just that there are
cases, or so it seems, where it is not clear how to deal with
the issue on my part. For example, hard links (-H). How are
hard links handled on one drive to be copied over to another
and is it guaranteed to work? I could not get my mind around
this one so I did not want to take a chance. As for ACLs (-A),
what exactly is being handled here and does this work for ALL
Oses concerned - do they follow the same "standard"? I am thinking
about Vista in particular, so I did not want to experiment on this
one either. As for extended attributes (-X), I have no clue exactly
what this is. I guess I have to someday take the time to do more
research before messing around with these rsync options. This is a
particular reason why I am using dd/rescue & resizing - it works sans
Vista, which I have yet to try.
Also, have you looked at [1] wrt copying while maintaining SElinux
contexts?

Yes, I am familiar with SeLinux to a point of creating them and
"permentizing" them. Symbolic links are one of the nasty ones that
take some getting used to though.
