![]() ![]() I installed it just after having installed Big Sur at the time. How clone a Time Machine backup APFS volume? I have a three months old external LaCie D2 Professional drive with two volumes, one being a TM. I'm waiting for the tool to do this, or, if it already exists, for a clear user's guide. APFS systems disks simply NEED to be RELIABLY and VERIFIABLY cloned. Time Machine is NOT a backup utility but an unnecessarily complicated copy utility, prone to errors that should NEVER happen with a backup tool. Given that Time Machine is, at best, a form of Russian roulette (on the two occasions where I tried to use it in actual need, it once provided me with a non bootable system disk and, on the second occasion, where I asked the migration assistant to get the configuration from a freshly created Time Machine data set, it missed several HUNDREDS files in both cases, I was only saved because I'm a firm believer in belt-and-suspenders policy and had other types of backups available this, while the Time Machine save operations had never given a single error message when doing their work), Apple owes it to its installed base to provide a reliable way to save their systems. What I am saying is that, for Apple to force users to have APFS system disks without providing a way to create verified clones of these disks, is simply a way to send them to their doom sooner or later. DU does it for HFS+ system disks, even if it is tedious, but one should have a realistic approach to the problem: short of implementing RELIABLE disk shadowing, an offline backup is the only way to create a verified clone. CCC does a good job but does not (yet?) provide any option to verify the integrity of the saved data. This is simply a question of survival for someone who depends on her/his computer for important or even vital matters. However, please, take note that I am talking of the need to have a VERIFIED backup clone of the system disk. ![]() At best, when told to, it verifies checksums on previously saved files, which, while good, is still not enough. I'm aware that some third party backup softwares say they can create such a clone (I do have CCC V5, but haven't yet tested this feature with APFS system disks, it's still on my "to do" list), but even CCC does not perform a complete "Verify" pass on its target volume. So the question is: "How can one clone an APFS system disk with DU and obtain a bootable clone"? There's no way I'm ready to do production work on a system where I can't clone the system disk and obtain a verified bootable copy of my system as a fallback system disk in case of a problem with the internal disk. For information, the target disk is a newly created APFS partition on an external Thunderbolt/USB3 rotational disk (most of the other partitions on this disk are still HFS+), if this is relevant to the issue. Then I'm left with a useless target volume, only good to be reformatted. DU informs me that "APFS inverter failed to invert the volume - Invalid argument" and then "OSStatus error 22". Then, the target volume inversion fails (by the way, what on Earth is this "target volume inversion" and what is it needed for?). But when trying to clone an APFS system disk, the works progresses smoothly until the last step. Using Disk Utility to clone an APFS data disk works fine, without any issue. And I still can't envision moving to it with an SSD system disk, as I haven't yet been able to figure a way to clone an APFS system disk with Disk Utility.
