This is a FYI for SD! users.

I've been using SD! to backup my /Users Volume. This was done by first Cloning my /Users volume and then periodically using the Smart update.

Recently I purchased Drive Genius 2 and decided I would defrag the /Users cloned volume. It failed quickly saying the file system was corrupted with severe overlapping extents. I then used the Drive Genius 2's facility for repairing the /Users clone volume and it failed. I then used Disk Utility to repair and it failed.

I've used the /Users cloned volume at times and the system had not reported problems to me.

I'm now thinking that either SD! has been doing bad things during its Smart Update or somehow my running system has somehow corrupted the /Users cloned Volume when being used of when simply mounted in read/write mode.

I'm now in the process of deciding if to continue using SD! for cloning and Smart Updating my /Users clone volume or to use the Drive Genius 2 to replicate my /Users to a backup volume, or to use some completely different process or Application.

This is just a heads up and will also say this may in fact be a problem unique to me and my system.

It seems to me that for any SD! operations the disks/volumes must either be unmounted on a running system of be done in single user mode.

I've been cloning my boot volume regularly while running on my boot volume - this now doesn't sound like a 'good practice'.

I can say the same thing for initial Cloning and Smart Updating the clone of my /Users Volume.

I notice that Drive Genius 2 refuses to do any of the above type SD! operations unless the system is booted from its special Leopard boot disc. This ensures all disks/volumes are unmounted and not in use.
