"Time Machine, CCC, SuperDuper, etc. After my backup disk failed and I wiped all my previous time machine backups, I have been looking for a new backup/cloning utility to use for my production machine"
Yours seems to be but one more report of Time Machine failing in a "moment of need". Numerous reports have been posted here on MR on just that subject.
I would NOT trust Time Machine as a backup. Further, you can't boot from a TM backup in a dire emergency.
I'll reckon that for the majority of Mac "home-users", that "moment of need" comes when they try to boot their computer and find..... that they can't.
Next comes fiddling and fooling (perhaps using an Apple system software or "restore" DVD).
At some point, they come to the conclusion (rightly or wrongly) that their OS has failed or become corrupted, and that they need to reach for "a backup".
And they try the TM backup -- and run into problems. Of course, they can't boot from it (a given). But they can't even "get at" their data when booted from a DVD.
ALL THIS COULD HAVE BEEN AVOIDED (shouting intentional) --- IF they had used either CarbonCopyCloner or SuperDuper to generate a "bootable clone" of their internal hard drive.
With a bootable backup, you just connect, power on, hold down the option key, and pick your backup from the Startup Manager. And then, off you go.
Booted externally, you can now either "attack" the problem internal drive with diagnostic/repair software, and even if the drive itself has failed, you can "keep right on going" from the point of failure, until the internal drive is restored or replaced.
This simply cannot be done with TM.
Having a bootable backup is the key to insulating one's self against software and drive problems on the Mac. Without one, EVERYthing becomes more difficult.
At this point we're going to get the replies that "TM and CCC/SuperDuper are designed for different purposes", blah, blah, blah.
Please clarify for me:
If one keeps a bootable CCC/SuperDuper backup, and maintains it regularly (say, daily or even every few days), exactly HOW different are the backed-up files going to be from TM?
Oh, yes, you're going to reply that one doesn't have "archival copies" of "changed files", but who wants or needs 20 copies of the SAME file? I realize that a very few might need to thumb back through their "version changes", but most people don't need or maintain a backup for this reason.
Again, most folks reach for their backup drive when there's a problem with the main drive that prevents it from booting. And for this, TM is all but useless.
