With Carbon Copy Cloner, your data and the operating system's data are all preserved on a bootable volume, ready for production at a moment's notice. When disaster strikes, simply boot from your backup and get back to using your Mac. How to backup / clone your Mac OS X hard drive with the free software called carbon copy cloner.http://www.tech2buzz.com. In this video, I'm going to show you guys how to clone a file, a folder, or an entire drive using a application called Carbon Copy Cloner. It is a very strai.
Carbon Copy Cloner is a popular software that lets Mac users easily back up entire disks and partitions on macOS. As macOS Big Sur is about to be released to the public, the developers behind Carbon Copy Cloner have now alerted their users about potential compatibility issues with the latest version of Apple’s operating system.
With Carbon Copy Cloner, users can create advanced backups of a Mac hard drive while still keeping it functional and bootable, which is great to ensure you’ll never lose your data. However, macOS Big Sur brings fundamental changes to the way the Mac manages its volumes, and this impacts software like the Carbon Copy Cloner.
One of the main under the hood features introduced with macOS Big Sur is a new protection layer called “Signed System Volume” that seals and encrypts the volume in which macOS is installed. Third-party tools can still make backups of the Mac’s internal storage, but they’re not bootable and some things become inaccessible.
The system now resides on a “Signed System Volume”. This volume is cryptographically sealed, and that seal can only be applied by Apple; ordinary copies of the System volume are non-bootable without Apple’s seal. To create a functional copy of the macOS 11 System volume, we have to use an Apple tool to copy the system, or install macOS onto the backup.
The latest version available of Carbon Copy Cloner (5.1.22) works with macOS Big Sur, but it’s only capable of creating copies of the system volume that are not bootable. The developers responsible for the software have claimed that Apple is aware of this limitation and is currently working to resolve it.
Until then, if you really depend on macOS bootable backups generated by Carbon Copy Cloner, you might want to avoid installing macOS Big Sur once Apple releases it for all users.
Apple hasn’t announced when macOS Big Sur will be officially available to the public, but the company will hold a special event focused on Macs next Tuesday — so the launch date is probably close.

Starting in macOS Big Sur (11.0), the system resides on a cryptographically sealed 'Signed System Volume'. That seal can only be applied by Apple; ordinary copies of the System volume are non-bootable without Apple's seal. To create a functional copy of the macOS 11 System volume, we have to use an Apple tool to copy the system, or install macOS onto the backup. CCC cannot use its own file copier to establish an initial bootable backup of your Mac's startup disk. When you configure a CCC backup task to make a clone of a Big Sur startup volume, CCC will use Apple's APFS replicator (named 'ASR') to create the initial clone. For subsequent backups, CCC will use its own file copier and will copy just the differences from your Mac's Data volume.
What to expect as you configure your first backup task
Carbon Copy Cloner Mac
When you select an APFS volume group (e.g. your macOS Big Sur startup disk) as the source to a task, and a destination that is not an already-established Big Sur volume, CCC will offer some choices for how to proceed with the task depending on how the selected destination is configured. We recommend that you dedicate a volume to the backup task, because the volume will have to be erased to establish a bootable backup.
Erase the destination
When you select this option, CCC will configure the task to use Apple's APFS replicator to clone the selected source to the selected destination. When you start the task, the destination will be immediately erased. SafetyNet is not applicable in this configuration, so be sure that you have selected an empty volume, or a volume that has data that may be deleted (e.g. an old backup).
Add a volume
If the selected destination is an APFS-formatted volume, and if the volume's container has enough capacity to accommodate a complete backup of the source volume, CCC will offer an option to add a volume to the destination APFS container. When you choose this option, your selected destination is not erased, nor affected at all by the backup task. Instead, CCC will add a new volume on the destination and use the new volume as the dedicated backup for the source.
Data Only backup
If you cannot or do not want to make a bootable backup of the selected source, and you also do not want to erase the selected destination, you can select the Data Only option. When you select this option, CCC will select the Data volume of your selected source as the source to your task, and will not erase the selected destination. This option is convenient if you have an existing encrypted backup volume that you would like to continue to use without erasing or decrypting it. volume?
Highly perceptive people may notice that the name of the destination volume changes as Apple's volume replicator goes to work. An additional volume may appear in CCC's sidebar as well. This is normal. These volumes will be aggregated into a 'volume group' and presented as a single volume, and CCC will rename the destination to its original name when the replication is complete.
If Apple's APFS replication utility fails and you see an ASRDataVolume or ASRNewVolume persisting, then you may delete those vestigial volumes in Disk Utility. Simply select the volume, then click the '-' button in the toolbar.
Do I have to erase the destination to make a bootable backup?
If your Mac is running Big Sur, yes. As of macOS Big Sur, we're required to use Apple's APFS replicator to establish a bootable clone of an APFS volume group. We're unable to leverage the SafetyNet feature, and it's no longer appropriate to store other data on the backup volume. You must dedicate a volume to your bootable backup. Once your bootable backup is established, CCC will use its own file copier to update the destination Data volume in subsequent backup tasks.
Can I use my backup disk for other purposes as well?
Carbon Copy Cloner Mac
Yes. We recommend that you add an APFS volume to the destination APFS container and use that new volume for either your dedicated CCC backup, or for your other content. As long as the CCC backup and the other content are stored on separate volumes, these can coexist peacefully on the same physical device. Likewise, you may add a partition to your backup disk if the destination is not APFS formatted. For example, if you have an external hard drive that already has content on an HFS+ formatted volume, you can add a partition to the disk and use the new partition for your CCC backup.

Can I exclude some content from the initial backup?
If your Mac is running Big Sur, then it is not possible to exclude content and produce a bootable backup. If you must exclude content from the initial backup, then we recommend that you proceed with a option. Other volumes on the same physical device will be unaffected. Regardless, we never recommend that you back up to a disk that has data on it that is not backed up elsewhere. If those other volumes are not yet backed up, then back up that data before proceeding.
I added a volume, but I don't want the extra volume after all. Can I delete it?
Yes. Choose Disk Utility from CCC's Utilities menu, select the volume you would like to delete, then press the '–' button in the toolbar to delete that volume.

Can I clone to an encrypted volume?
Carbon Copy Cloner Mac Os Mojave
You may select an encrypted volume as the destination, but the volume will be erased, and will not be encrypted when the task completes. Apple's APFS replication utility will not preemptively enable FileVault on the cloned volume. To enable FileVault on the destination, you can boot from the backup volume and enable FileVault in the Security & Privacy Preference Pane.
