One specifies inherited ACLs because one wants child folders or files to
have said attributes (e.g. read/write by members of group family). Some
backup/restore operations lose the ACLs and hence, the affected folders
can no longer satisfy their intended purpose.

I don't know; maybe Catalog entries or extended Finder info. All I know
is that Retrospect and the various psync, rsync and other file copy
operations either didn't preserve the ACLs or I didn't know how to
specify that they should and, as a result, I had to reconstruct the
appropriate ACL after restoration.

Inherited ACLs are those which were defined for a (grand)parent
directory and specified to be passed on to its children and
grandchildren.

Some attributes and properties are specified by structures not known to
some "cloners" and, while they may do a perfectly respectable job or
copying the file structure, they may fail to properly copy all the
metadata associated with the directory or file.

That *is* nifty.

Now all I need is for it to somehow automagically clone that
pesky BootCamp Windows discoid along with the Mac one without
me having to remember to do anything...

It was, yesterday.

"Tomorrow, and tomorrow, and tomorrow, Creeps in this petty pace from
day to day To the last syllable of recorded time, And all our yesterdays
have lighted fools The way to dusty death."

ACLs are a special form of file/folder permissions that, when set, takes
precedence over the standard UNIX permissions. They were first
introduced to OS X in Tiger, and Leopard is the first OS X to use them
extensively in the OS (The ACL on your home directory prevents you from
accidentally renaming it, for example.)

I share iMovie projects, iPhoto and iTunes libraries between my wife's
and my user accounts. All the shared stuff is in
/Users/Shared/OurFiles. Because of OS X default file/folder permissions
(all new files and folders are read-only to everyone other than the
creator) I had to set up a system to automatically change all new
files/folders to read+write for both me and my wife. Setting an ACL on
the /Users/Shared/OurFiles folder that is set to propogate down a chain
to all child folders/files is how I did it.

An example of how to set this up is here:
http://www.macosxhints.com/article.php?story=20050904072808460&lsrc=osxh

Until today, any backup and/or cloning program would, at most, copy only
the ACL at the very top level of the hierarchy, and ignore any ACL that
was inherited from the parent folder. So, for me to fully restore my
data from backup would mean and having to restore all of my ACLs by
hand. Which is quite time consuming for 50GB of files.

Until today. SuperDuper saves the day.

The previous version did that too.

I didn't know that. I examined the "About" dialog because SU crashed
while updating. Even though the info seemed correct and the updated
version launched OK, I opted to download the .dmg file and replace the
suspect executable.

Mine did that too.
