CARBON COPY CLONER UPDATE
CARBON COPY CLONER SOFTWARE

The fine-print at the bottom of the window should be eliminated it is long and confusing at best, and ambiguous as to what will actually happen. The user should know exactly what will happen, since the behavior could change unpredictably, depending on current system status (eg apps running with open files, or not). This non-deterministic behavior is confusing, and needs to be addressed in the user interface. So CCC thus chose to perform a file-level incremental clone, which is what I wanted all along. The difference? Today I had files open on the source volume (as I almost always do), so that CCC could not unmount it. Retesting today showed totally different behavior.

At that point, I had no backup left, since it had just been wiped out.

This caused software I had running (Dropbox) to immediately complain, which startled me, which is why I then clicked Stop. In my case, a particular detail contributed: CCC was able to unmount the source volume, and thus was able to wipe out the target volume in preparation for a block-level clone. I took it to mean “will be efficiently updated”, since that’s what had always happened for me before. The fine print at the bottom of the main window that states “What will happen” is contradictory it’s an either/or, so the user can’t know what will really happen. For me at least, that totally defeats the purpose of using CCC for backup.ĬCC does issue a 'may delete files and folders' warning, which I understood/understand to mean files and folders that no longer exist on the source volume, not all files and folders. That means wiping out the target volume and recopying the entire source volume, or at least all 1.8TB of data on it. This saves considerable time, since only changed items are copied.īut with the 6TB volume, CCC chose to do a block-level clone this particular time (explanation below). In that case, CCC always does an incremental clone, exactly what I want. I was contacted by a very concerned Mike Bombich, author of Carbon Copy Cloner, and I believe I now understand what happened.Īll my past cloning for backup purposes has been from a 3TB volume(with 1.8TB of data) to a 2TB volume. The facts I stated have not changed, but there is an explanation.
