Disk image from bootable disk in 10.15

Disk image from bootable disk in 10.15, h2

I like to make a bootable disk image (Sparse) as backup from my OS disk in 10.15. Does anybody know how to do this? Used to be simple before the OS was split in to two parts. Not sure how to do this now.

Alternatively, how to create a APFS disk image that allows a backup application to make a bootable sparse image.

PS and yes I am aware one cannot backup from a disk-image but it would be used to restore in case of emergency.

MacBook Pro 15″, macOS 10.13

Time Machine > how to back up to a sparse bundle Hello A few days ago I connected an external 8TB drive to a Mac mini running Ventura. I followed this article, Backup disks you can use with Time Machine - Apple Support, section Mac shared as a Time Machine backup destination. There are no issues with backing up two Macs from the LAN, a High Sierra and a Big Sur Mac. When it came time to backup the Mac mini, which hosts the Time Machine destination, I discovered that erase the entire drive is a required prerequisite. I thought about partitioning the drive but I don't like the risks. I am open to using a disk image however. From what I understand from the Disk Utility Help, a disk image can be created but I unclear on which of the two I should choose when creating the blank disk image for storage; Sparse bundle disk image: Same as a sparse disk image (below), but the directory data for the image is stored differently. Uses the .sparsebundle file extension. Sparse disk image: Creates an expandable file that shrinks and grows as needed. No additional space is used. Uses the .sparseimage file extension. I can't determine which is appropriate because help mentions this "the directory data for the image is stored differently" without any detail. Disk Utility Help also mentions: If the disk image will be used with a Mac that has a solid state drive (SSD) and uses macOS 10.13 or later, choose APFS or APFS (Case-sensitive). If the disk image will be used with a Mac with macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled). If the disk image will be used with a Mac or Windows computer and is 32 GB or less, choose MS-DOS (FAT); if it’s over 32 GB, choose ExFAT. It would appear that I should follow the recommendation in the first bullet point because the Mac mini does have an internal solid state drive and uses macOS Ventura. I would need some guidance on what to choose from the options above. I am guessing that after the requirements above are understood, that the image should be mounted on the desktop so that I can choose it when setting up Time Machine correct? The same would apply, mounting to desktop, when I need to restore. I would appreciate any assistance. Thank you! reference: Create a disk image using Disk Utility on Mac – Apple Support (AU)

Backing up OS 10.15 to external USB disk what format should the disk be? I use ChronoSync (besides from TM) to back up my OS to an external USB disk and to a network drive. Presently I am using 10.13 but will soon move to 10.15. In order to back up properly I like to know what format the USB disks should have to make sure that if I need the backup it works perfectly. Or if I want to use one of the USB backup disks to start the computer up from, like in an emergency making sure that it works flawlessly. Thanks.

Back Up Drive format My boot drive is an external SSD formated APFS. If I want to make a bootable disk image using SuperDuper! on another external drive does it have to be APFS also ? If no, is it better that it is or does it not matter ?
