Selecting an external drive as your backup drive follows the same steps. The restore button lets you copy your backup files to your primary drive these are the identical data that macOS recovery mode uses to restore your Mac OS to your hard disk if it fails. The disk utility comes with a variety of functions and settings. You can view the storage disks with their volumes, including internal and external hard drives after it opens up. Open disk utility from the spotlight (command + space) or from the utility folder in your program to generate a storage backup. Creating a Storage Backup with Disk Utility For example, our Time Machine backs up automatically every other day or so. The problem is that you have no control over incremental backups and can't specify which backups should be maintained. The objective is to get you back on your feet as soon as possible. Time Machine stores the most current copies of a backup on your Mac, which is intended to provide you with the most recent 'image' should you buy a new computer or need to do a factory reset. The distinction between cloning and Time MachineĪ clone is a 'image' of your hard drive, which means it's a compressed version of your whole hard drive that you may go back to at any moment.Īpple's default technique for generating incremental backups is Time Machine. DoYourClone for Mac is able to securely and easily clone macOS Catalina to an external hard drive and make the external hard drive be bootable.Time Machine archives your whole starting volume (as with any additional volumes you choose), allowing you to restore a Catalina drive to an earlier version of macOS.Apple adopted this strategy to improve security by separating read-only system files from your changing data, home directory, preference files, and everything else on one drive.īut what if you wish to clone your starting disk and build a backup that can be used to restore a broken drive or Mac, or even boot from? Fortunately, all of the software you require is current. This allows macOS to appear as a single disk by joining two distinct volumes. Until macOS 10.15 Catalina, Mac users understood that their starting volume was exactly that: a single volume! (Okay, Fusion drive users have two physical drives that are controlled by software to seem as a single "disk drive," but it's not the same as the data organization that is a volume on a drive.)Īpple uses a feature called "volume group" in APFS (Apple File System), as I mentioned a few months back.
