Ccc Bootable Clone

Though it may be possible to clone an APFS macOS 10.14 Mojave boot drive to HFS+, it is trickier and does not work in all cases. Also though CCC v4 may work, it is not certified to work with Mojave, so you would need CCC v5.

Creating a backup of your important files can be a lifesaver. Whenever you encounter an error, file corruption, or any problem that prevents you from accessing your files, you can always rely on your backup to avoid data loss. Among the many backup tools available for Mac, Carbon Copy Cloner or CCC is one of the most reliable.

What Is Carbon Copy Cloner?

Aside from being used to create file backups, Carbon Copy Cloner can also make complete images of your computer or clone your hard drives. This tool is quite flexible because you can either back up the whole disk or just a part of it to your external hard drive. It is capable of creating bootable backups and booting from your backup if a disaster strikes your hard disk.

You have the option to choose what time you want the backup to be processed — hourly, daily, weekly, monthly, and others.

CCC is equipped with a smart update function, which prevents you from copying all the files every time the backup is initiated. This means that the app will only update the newly added or modified files. You can also use Carbon Copy Cloner to create bootable backups. In case your hard disk fails or becomes inaccessible, you can boot from your bootable backup in no time.

CCC 5 is the latest version of this software and it works with macOS version Yosemite (10.10) up to the latest Big Sur (11.0). CCC 4 only works up to High Sierra (10.13).

With the upcoming public release of macOS Big Sur, Bombich Software, the developers behind Carbon Copy Cloner warns of compatibility issues with macOS Big Sur. CCC has reported these issues to Apple and they are still waiting for an official response. Let’s look at some of the known issues and what you can do about them.

Compatibility Issues with Carbon Copy Cloner on Big Sur

There are three main issues that users have to be aware of when using CCC 5 on macOS Big Sur. Let’s discuss them one by one and the workarounds offered by CCC.

Issue #1: Big Sur startup disk can’t be cloned

With CCC, users are able to create advanced backups of your hard drive while keeping it functional and bootable. This ensures that you never lose your data if an accident ever occurs. But with Big Sur, the Apple Software Restore does not have the capability to close the Big Sur startup disk because of a broken seal. Apple’s Signed System Volume, which is very proprietary in nature, is preventing ordinary system calls and copy software from cloning the macOS System volume.

The Signed System Volume has been implemented starting macOS 10.15.5, but CCC was able to work around this restriction by using Apple’s APFS replication software. But with Big Sur, ASR no longer creates a bootable copy of the macOS System volume.

Fix: Apple has recently released the macOS 11.0.1 which resolves some of the issues with Apple Software Restore or ASR utility. However, CCC is still testing whether this patch has resolved all errors and if CCC is now able to create bootable backups.

If installing this update does not fix the problem for you, you can try the workaround suggested by CCC. Make your backup drive bootable by directly installing Big Sur onto the backup disk. You can also employ the help of Migration Assistant to restore all of your data and files to a clean installation, without having the need to install macOS on your backup drive.

Clone bootable drive

Issue #2: Creating a bootable backup requires erasing the destination drive

With the release of macOS Big Sur, the system is now located on a cryptographically sealed “Signed System Volume”. And this seal is applied by Apple itself. This means that when you clone the System volume, they are not bootable copies because they do not have Apple’s seal. To create a bootable macOS 11 System volume, CCC uses the ASR tool mentioned above. Unfortunately, the ASR only copies entire volume groups, which includes System and Data, not just the System volume. Because of this, CCC has to erase the whole destination volume, including the existing snapshots on that volume, whenever a macOS update is released, in order to update the system on the destination.

Fix: CCC has reached out to Apple to request that the ASR be allowed to clone the System volume only. CCC is only waiting for the implementation from Apple. While the fix is not rolled out yet, CCC recommends erasing the destination only when you establish the initial backup, then use the built-in file copier to maintain your backup of user data, applications, and system settings. If you wish to update the macOS on the backup drive, boot your Mac from the backup drive and install any updates using Software Update in the System Preferences app.

Issue #3: Inconsistent display of ASR clones in the Startup Disk Preference pane

In the previous CCC versions, the Startup Disk Preference Pane shows all the available startup volumes, including those that were cloned by CCC, regardless of how they were copied ( via ASR or file copier). But in Big Sur, there are instances when the cloned volumes do not show in the Startup Disk Preference Pane, even though they are bootable.

Fix: If you want to boot from the cloned volume, reboot your Mac while pressing the Option key, then choose the cloned volume found in the Startup Manager. Then, you can set the startup disk to the current startup volume.

Summary

Although Carbon Copy Cloner has released a version that works with macOS Big Sur, the developers are aware of the compatibility issues and limitations of the backup tool. It is working together with Apple to address these issues and hopefully iron everything out when Big Sur is finally released to the public. For now, we hope that the suggested workarounds above should help.

If you’re running into errors and your system is suspiciously slow, your computer needs some maintenance work.

Steam for mac os x. Apple introduced a new filesystem in macOS High Sierra, so naturally you may be wondering how Carbon Copy Cloner deals with this and how this new change might affect your backups. You might even be wondering, 'What's a filesystem?', so we'll start with that, and gradually move into more technical details.

What's a filesystem?

Make Clone Bootable

The file system is perhaps the most important piece of software on your Mac. It’s also one of the most transparent, at least when it’s working correctly. Every user and every application uses the file system. The file system keeps track of and organizes all of the files on the hard drive, and also determines which users and applications have access to those files. The file system also keeps track of how many files you have and how much space they consume. Every time you look for a file, open a file, move a file, save a file or delete a file, it's the filesystem that is fulfilling that action.

Why is Apple introducing a new filesystem?

Apple’s legacy file system, HFS+, has worked well for almost 20 years, and Apple has made consistent improvements to it over that time. For example, Apple added support for extended attributes, file system compression, file system journaling, and full-disk encryption. All of these new features were added to keep pace with new operating system features and to make the file system more reliable. But that file system was created initially for Mac OS 8, and was designed for platter-based hard drives. Storage technology has changed a lot over the last 20 years, and modifying HFS+ to keep pace with those changes has proven increasingly difficult. To meet the challenges of new OSes and new storage technology, Apple introduced the Apple File System, or 'APFS' in High Sierra.

When I upgrade my Mac to High Sierra (or later), will my startup disk be converted to APFS?

When you upgrade to macOS High Sierra, systems with all flash storage configurations are converted automatically. Systems with hard disk drives (HDD) and Fusion drives won't be converted to APFS on macOS High Sierra. When you upgrade to Mojave, HDD and Fusion volumes are also converted to APFS. You can't opt-out of the transition to APFS.

If I first upgrade to High Sierra on an HDD, and then clone to an SSD, will the SSD be converted to APFS?

If you're running macOS High Sierra or Mojave, then neither the HDD nor the SSD will be automatically converted to APFS. You can choose, however, to erase the SSD as APFS prior to cloning to it. Both APFS and HFS are valid destination formats when using Carbon Copy Cloner 5 on High Sierra and Mojave. When making a backup of a macOS Catalina system volume, CCC will automatically convert the destination volume from HFS+ to APFS, but only after your explicit approval of the action.

If the OS upgrade converted my startup disk to APFS, what do I need to do to my backup disk? Do I have to erase it as APFS?

You don't need to do anything at all to your backup disk after upgrading to macOS High Sierra or Mojave (and again, on macOS Catalina, CCC will automatically convert the destination to APFS, so you still don't have to do anything to the destination volume). Having an HFS+ backup of an APFS-formatted High Sierra or Mojave startup volume is acceptable; that will function just fine for any future restores, even to an APFS-formatted volume. If your backup disk is an SSD, or if you were planning to erase the destination anyway, we do recommend that you erase it as APFS.

I'm running Mojave — can I erase my HDD destination as APFS? Are there any advantages to using APFS on the destination?

If you were planning to erase your destination volume anyway, we recommend that you format the volume as APFS. While enumeration performance of APFS on a rotational disk is still significantly worse than HFS+ on the same hardware, there are some other advantages to choosing APFS rather than HFS+. For example, an APFS destination can store snapshots from which you can do point-in-time restores. APFS volumes also support sparse files, and you're less likely to run into name comparison problems (e.g. when files on the source APFS volume have Unicode characters like 'é') when backing up to an APFS-formatted volume. You also cannot boot a T2 Mac from an HFS+ encrypted volume, so if you have a T2 Mac and encryption of the backup is required, you must choose APFS.

Can I use CCC to clone an APFS startup disk to another Mac?

The macOS installer applies a firmware upgrade to your Mac when you install the macOS upgrade. This firmware upgrade cannot be made part of the cloning process. Only the macOS Installer can upgrade a Macintosh to support APFS. If you attempt to clone an APFS volume to a Macintosh that has not yet received the firmware upgrade from the macOS Installer, that Macintosh will not be able to boot from the APFS volume. Once your Mac has received the firmware upgrade via the macOS Installer, your Mac can boot from a CCC bootable backup on an APFS volume. Note, however, that every major MacOS upgrade may require a new firmware upgrade to allow use of the newer operating system.

Note that this is also applicable to a Macintosh running in Target Disk Mode. If you upgrade one Mac to High Sierra (or later) via the Installer, you cannot boot a second Mac into Target Disk Mode, attach it to the first, then clone High Sierra (or later) to the Mac in Target Disk Mode. The required firmware upgrade cannot be applied to the Mac that is booted in Target Disk Mode, you must run the macOS Installer on that second Mac. Once the second Mac has received the firmware upgrade via the macOS Installer, you can clone the first Mac to the second Mac booted in Target Disk Mode.

Does CCC support encrypted APFS volumes?

Yes, CCC 5 can clone to and from encrypted APFS volumes (aka FileVault encryption). Note that CCC doesn't play any role in the encryption process – encryption is a function of the volume, not of the tool that's writing a file. Codec ac3 for mac os. If you enable FileVault on your startup disk, then the files on your startup disk will be encrypted. Those files are decrypted on-the-fly by the filesystem when they're opened by an application. Likewise, if you enable FileVault on the destination volume (e.g. via the Security Preference Pane while booted from the backup), then the files on the destination will be encrypted. CCC doesn't have to encrypt those files, they're encrypted on-the-fly by the filesystem as the bits are written to disk.

Bootable Disk Clone Software

I heard that APFS has a 'cloning' feature. Is that the same as what CCC is doing?

No, the cloning functionality within APFS is completely unrelated to the cloning that CCC performs.

APFS cloning allows the user to instantly create copies of files on the same volume without consuming extra storage space. When cloning a file, the file system doesn’t create copies of the data, rather it creates a second reference to the file that can be modified independently of the first file. The two files will share storage on the disk for portions of the files that remain identical, but changes to either file will be written to different parts of the disk. APFS file cloning only works when you make copies of a file on the same volume (e.g. duplicate a file or folder in the Finder). CCC is typically copying files between volumes, so APFS cloning isn't applicable for that kind of task.

Clone Bootable Drive

The important take-away is that APFS file cloning can save you space on your startup disk, but CCC cloning can save your data if your source disk fails. They serve completely different purposes; APFS file cloning is not at all related to making backups.

Why doesn't the disk usage on my backup disk match the disk usage on the source disk?

CCC's global exclusions as well as the SafetyNet feature have traditionally led to legitimate differences in disk usage in the past. The aforementioned APFS file cloning feature, however, adds a new dimension to this concern. While APFS file cloning saves space on your source volume, those space savings can't be consistently applied when copying your files to another volume (because Apple doesn't offer a way for us to determine that one file is a clone of another). Making matters worse, Finder does not accurately represent the true disk usage of your files. Finder doesn't take into consideration whether one file is a clone of another (again, because Apple doesn't provide a way to make that assessment), so it sums up the total size of each file and folder, presenting a total value that is possibly astronomically higher than the capacity of the disk.

Ccc Bootable Clone

If you convert your Mac's disk to APFS, understand that the disk usage on your source and destination may never add up, and therefore may not be a reliable measure for comparing the source and destination.
