![]() Suddenly your computer has a catastrophic failure. You've been backing up for 5 years using an app. Add in a dose of reality and this is what will happen:ġ. Why? Because if you use an application to back up your files you also need to use it to restore them. I am generally averse to using any proprietary backup software. It will grow but not by any dramatic rate increase over the next few years. Do you feel a 2TB size is sufficient to back up a music library with a current size of 850GB. I've thought about getting two more 2TB SSD like my SSD now used for my Music Library to use as the backups. ![]() I have a reason to use external portable versus desktop units for backup and storage. Can you advise which software solution would be best and how to properly set it up? Additionally the HDD I use now are external portable 4TB units. I want both my MacBook and my Music Library which is on an external SSD to be backed up at the same time. ![]() I have used Carbon Copy Cloner in the past but I would consider myself very novice in understanding the set up and advantage of using one or the other. I'm unsure if it is the HDD or Time Machine causing this unusual (it seems to me) long back up time (several hours vs a few minutes). I am experiencing some slowdown in the time it takes to backup. You can use Migration Assistant to migrate data from your CCC backup to a clean installation of macOS.I have primarily used Time Machine on two external HDD as primary and secondary (weekly/monthly) backups. Migrating data from a CCC backup using Migration Assistant Choose the option to Reinstall macOS Big Sur.When Recovery has loaded, click on the WiFi option and join a WiFi network if your Mac is not connected to a wired network.Click on the Options button, then click the Continue button.Shut down your Mac, then power it on while holding down the Power button until the startup options are loaded.Proceed to install macOS onto your backup disk.When prompted to select a disk, click the Show All Disks.Download and open the macOS Installer:.If your data-only backup resides on a non-encrypted APFS volume, you can install macOS onto the backup disk to make it bootable. Click on the Destination selector and choose your destination.Drag the Macintosh HD - Data volume from CCC's sidebar onto the Source selector.Click the Show Sidebar button in CCC's toolbar.If you would ultimately like to make the backup bootable, erase your destination volume as APFS in Disk Utility.You can perform the following steps to manually configure a data-only backup. In some cases CCC will configure your task for a data-only backup automatically. A data-only backup is not bootable, however the backup can be made bootable by installing macOS onto it, or you can use the data-only backup as a source to Migration Assistant. The System volume, which contains only about 15GB of read-only system files that are installed by the macOS Installer, will not be copied. If you're unfamiliar with the APFS Volume Group concept that Apple introduced in macOS Catalina, you can learn more about it here:įor a data-only backup, CCC copies the entire Data volume within that APFS volume group. In some cases CCC will create a data-only backup of a macOS startup disk. ![]() A data-only backup is a complete backup of all of your data, settings, and applications ![]()
