Backup Apfs Drive To Mac Os Extended



Hi, My laptop is MacBook Pro 16-inch,2019. The system is Catalina 10.15.4. And I am using Samsung T7 use store my music stuff. However it was incredibly slow for me to load anything, I looked up and people are saying its because I have to format my T7 to MacOS Extended (Samsung T7 was originally ExFAT). Because Apple has had stunning success with APFS in iOS so far, you’ll probably want to upgrade your Mac to APFS, especially if your boot drive is Flash-based. Here’s a screenshot of the. (note: Some might notice and be confused that I'm using a drive called '2 TB backup encrypted HD APFS' as my backup source. I'm writing this after converting my other drive to Mac OS Extended, so for screen shots, I used my backup drive. See on the top where it says “Mac OS Extended (Journaled)”? Yeah, that’s the old format. My boot drive shows this: Before you upgrade, let’s just run a quick disk repair to ensure it’s all formatted correctly and is ready to go. That’s done by choosing the drive, then clicking on the “First Aid” button on the top toolbar.

Summary:This article shows you two risk-free ways to revert/convert APFS to HFS/HFS+.And if unfortunately you lose data after changing APFS to HFS/HFS+, don't feel panicked, just downloadiBoysoft Data Recovery for Mac to recover files with ease.

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.

I'm deciding to install MacOS High Sierra on my Mac this autumn. So, if I find APFS not useful, is it possible to convert APFS back to HFS+ via terminal or using Disk utility?

If you upgrade to macOS Catalina Big Sur 11, 10.15, Mojave 10.14 or High Sierra 10.13, the solid-state drive (SSD) will be automatically converted from HFS/HFS+ to APFS and there is no opt-out. However, even though the APFS file system is optimized for HFS+ with many advanced properties, many Mac users cannot get used to APFS and want to convert APFS back to HFS+. It is undeniable that APFS does come with some limitations and brings users troubles like drive corruption after converting from HFS+ to APFS.

Then you may ask, is it possible to convert/revert APFS back to HFS/HFS+? The answer is 'Yes' but with some precautions. This page will list what you should know when you revert or convert APFS to HFS/HFS+ and provide the details about the best APFS to HFS converter with no risk of losing data.

Notes on converting APFS to HFS/HFS+

Backup Apfs Drive To Mac Os Extended

First, as you may have noticed, there is a new concept called container in APFS. A container is the basic storage unit for APFS and each APFS container contains one or more APFS volumes. One of these APFS volumes will have macOS and each volume could have different APFS type: APFS, APFS (Encrypted), APFS (Case-sensitive) or APFS (Case-sensitive, Encrypted). As a result, there are some rules when you convert APFS to HFS/HFS+:

Allowed: convert APFS container to HFS+ (also named Mac OS Extended)
Not allowed: convert a single APFS volume to HFS+
Not allowed: convert APFS to HFS

What's more, you need to know that converting APFS back to HFS+/HFS will format your SSD and erase all data on it. Thus, please make sure you have a backup copy of the APFS container or the whole drive. If you already backed up your data on this SSD drive, read Part 1 to learn details about how to convert/revert APFS back to HFS. Nevertheless, if you have lost something important when you convert APFS to HFS+, you can skip to Part 2 to recover lost data after the conversion from APFS to HFS+.

How to revert/convert APFS to HFS+?

Method 1: Convert APFS to HFS+ in Disk Utility

Disk Utility is a built-in tool that can manage internal and external storage devices, including partitioning and formatting your disks, creating disk image, checking and repair disk errors, etc. So, you can convert APFS to Mac OS Extended (HFS+) with this natural APFS to HFS+ converter - Disk Utility.

Attention: This process is destructive to your data on the APFS container/drive. So please check again if you have a backup copy.

Step 1: Go to Applications > Utilities > Disk Utility.

Step 2: Select the drive that you want to convert/revert from APFS to HFS+.

Step 3: Click Erase on the top of the Disk Utility window.

Step 4: Complete the required name, select Mac OS Extended (HFS+) as the new format and then click the Erase button.

When the process finishes, you'll get a clean HFS+ formatted drive and you can then copy back your data.

Method 2: Convert APFS to HFS+ with Terminal

The Command line, or known as Terminal in macOS, is a powerful, text-only method for interacting with your Mac computer. If you are an experienced Mac user, using macOS's built-in command line would be an appealing way to convert/revert APFS to HFS+.

Step 1: Go to Applications > Utilities > Terminal.

Step 2: Type diskutil list and find the identifier of the APFS container.

Step 3: Typediskutil eraseDisk JHFS+ 'the disk name' /dev/'the identifier'. This process will wipe all the files in this APFS container and convert it back to APFS.

How to recover lost data after reverting/converting APFS to HFS+?

Conclusion

The newest default APFS for macOS Catalina/Mojave/High Sierra and later is not necessarily the best for Mac users. If you need to downgrade APFS to HFS+/HFS without data loss, backing up your data and reformatting your drive is always the safest choice, while if you are interested in new features in APFS, you can also convert HFS to APFS on Mac.

Apfs Or Mac Extended

Note: This will erase all data on the specified disk

Launch Apple's Disk Utility

Open a Finder window and navigate to Applications > Utilities and double click on Disk Utility.

The remaining steps vary considerably depending on the operating system you are running. Choose About This Mac from the Apple menu to determine your current OS, then make a selection below.

Show All Devices

Disk Utility offers a very simplified view of your devices by default. Unfortunately, this hides the devices that you need to select to modify the partitioning of your backup disk. Before doing anything else in Disk Utility, choose Show All Devices from the View menu, or from the View popup button in Disk Utility's toolbar.

Select the destination disk

Click to select the disk that you would like to use as the destination for your CCC task. This disk should not be the same as your startup disk.

The name of a new disk will often include the manufacturer’s name (e.g. WD My Book 111D Media...). A startup disk will often include the manufacturer's serial number in the title (e.g. TOSHIBA MK50...). Please pay particular attention to selecting the disk, not one of the volumes on the disk. You must select the whole disk to correctly initialize the device. If your disk is a Fusion device, you may erase the 'container' within it instead.

Unmount any volumes on the specified disk

Disk Utility occasionally has problems with unmounting a volume while attempting to erase it (e.g. because Spotlight prevents the unmount request). Click the Eject button next to any volumes on the disk to preemptively unmount them before erasing the disk.

Erase the specified disk

Click on the Erase button in Disk Utility's toolbar, then configure the name, format, and partitioning scheme of your disk. You can set the name to whatever you like, but set the Scheme to GUID Partition Map. If you do not see the Scheme option, go back two steps and select the whole disk device, not one of the volumes on the disk.

Choosing a Format for your destination volume

If your destination device is an HDD with a rotational speed of 5400RPM (or slower): (e.g. 'Slim' backup devices, 2.5' disks) APFS is not designed for these devices, macOS boot performance may be poor. You can format these devices as APFS and try to make a bootable backup, but if the performance of the device is too slow to be practical, then we recommend you choose Mac OS Extended (Journaled) for the format. If you are making a backup of a Big Sur or Catalina startup disk, you should create a from Disk Utility's Edit menu. If you chose another format, select the backup volume, then click the 'Partition' button in Disk Utility's toolbar.

Instructions for El Capitan and Sierra

Select the destination disk

Click to select the disk that you would like to use as the destination for your CCC task. This disk should not be the same as your startup disk.

The name of a new disk will often include the manufacturer’s name (e.g. WD My Book 111D Media...). A startup disk will often include the manufacturer's serial number in the title (e.g. TOSHIBA MK50...).

Erase the specified disk

Click on the Erase button in Disk Utility's toolbar, then configure the name, format, and partitioning scheme of your disk. You can set the name to whatever you like, but set the Format to Mac OS Extended (Journaled) and set the Scheme to GUID Partition Map, then click the Erase button.

Don't Use Time Machine

Click Don’t Use. You may use the same backup disk for both Time Machine and CCC backups, but if you do so, you must use a dedicated partition for the Time Machine backup. Otherwise Time Machine will consume all available space on the backup volume and make it impossible for CCC to use the backup volume.
