CCC Caution... or "why I'm an SD fan."

Doing some testing for a developer under 10.5.1, I mucked up my drive. Fortunately, I had a CCC clone from the day before, and just swapped out one drive for the other.

The good news: it booted, and I only lost about 18 hours worth of stuff.
The bad news: CCC isn't as accurate as SD (nor anywhere near as fast!) Several hidden system files ended up visible; some significant number of permissions were wrong; and some ACLs just "materialized" out of nowhere, requiring a few trips to the terminal.

CCC served it's main purpose: to get me thru until SD for Leopard arrives. But for those who are wondering why spend the bucks on SD... well, those are the reasons.

Hhmm, a pity. That also means that the backup-bouncer-0.1.2 test is not good as that showed that CCC did pass all tests successfully.

Cheers, Fons.

your problem does not reflect most peoples results. The Version Tracker and MacUpdate comments do not indicate you have a common problem. You should report this to CCC and to MacFixit. Lets find out if there is a real issue.

Naturally, results will vary. If everyone had the problem, you are correct, it would be common knowledge. Having spent over 25 years as a programmer on Apple brand machines, I have some familiarity with the issues involved.

I should point out that the drive I was cloning has over 2 million files occupying 289 gigs of drive space.

When I report this, I'll get back a request to verify it and run various tests. Since each backup takes 58 minutes, and I'm still trying to earn a living, I'm afraid I don't have the time to devote to it.

That said, the results were, for me, as stated. I'm not shilling for Dave. :-) and...I'll copy the CCC author, as well.

(In fact, I just now -before completing this reply- checked the CCC clone I made an hour ago: Mach_kernel.cfgsys; iNode16068125; my Authorization for MOTU and several other finder-invisible files on my source drive, are plainly visible on the cloned drive.)

It would be interesting to know if anyone else here has checked for, and seen a similar result. So far, thru several updates, and thru at least two full, from-scratch backups using CCC, this has been 100% repeatable.

Cordially,

Tracy

Not necessarily true: it may have passed the test wherein CCC did a fine job of cloning.

Note that I'm not saying my anecdotal experience is universal truth... only that it happened to me... several times.

I would assume, in fact, that my situation is the exception, not the rule. CCC has a good reputation.

Quick followup: I've now tested CCC on two more machines, with the same type of result (invisible files being made visible.) Hardly a crushing issue, but I mention it only to indicate that it was not (at least for me) and isolated incident.

Bottom line: use it!...... until SD comes out

OK... last word, published with permission. I reported the CCC issues to Mike, developer of CCC, and here is his reply:

"Hi Tracy:

Thanks for the info, and tact :-) I'm working to get an update to CCC out the door by New Years Day that should address most of the Leopard-specific issues.

Mike
"

CCC and SD

For some reason I feel products like these all need to be supported, so I've paid for both SD and CarbonCopyCloner. A programmer or company who cares enough to try to do a good job needs support.

And we probably benefit from a bit of competition.

I've also been testing Intego's Personal Backup X4, while we're waiting for SD to hatch. I corresponded with Intego tech support, who assured me that their cloning engine preserves all metadata, hard links, permissions, etc.

So far, my Leopard initial/incremental clones seem to be very solid, and the Intego UI is actually pretty slick. The downside is cost for this app. I agree that giving props to developers who are working hard to support the Mac community is a good thing. I'll be looking forward to the new SD like everyone else.
