Yes, exactly. Not only do you get incremental backups (only what's changed since the last backup), but your backup is bootable. If your internal hard drive crashed, you could put your external drive in your Mac and boot up without missing anything. .
Apart from the stuff that happened since you last backup, which if you are the average user, will be, errm, never,and even if you arent, might be days to weeks ago.
I don't understand why people make it an either / or, I do infrequent incremental CCC's to create a bootable, AND also use TM for regular backups, since most often its user error (mine) I need to recover from, and that wont get me back a file I deleted that that isn't on the incremental.
The super users who complain about TM and its inability to get you back in minutes instead of hours, arent thinking about the most common scenario, for the most common user, which is that
no one is taking backups, ever and even if you explained about the advantage of incremental regular bootable backups until you were blue in the face they would still never get round to doing it
TM does what its designed to do superbly with no fuss or muss, which is make backups automatic and simple
and ensure they occur. The lack of a bootable clone is irrelevant compared to the fact that it ensures backups are actually made. Whats the use of having a cloned bootable you can recover from instantly that's years old, which would be the case with most people?
