![]() ![]() However, if you always want the destination to match the source volume exactly, and you have no need for retaining older versions of modified files deleted from the destination since a previous backup, you can flip it off here. I have it enabled on my backups, and recommend you do as well. In short, this option helps protect you from overriding an old backup in a way that would remove a file you may need later. Files and folders that are unique to the root level of the destination.Files that have been deleted from the source since a previous backup task. ![]() Older versions of files that have been modified since a previous backup task.By default, CCC uses a feature called the SafetyNet to protect files and folders that fall into three categories: When CCC copies files to the destination, it has to do something with files that already exist on the destination - files that are within the scope of the backup task, and items that aren’t on the source at all. Here’s how the developer explains it in the app’s help file: The SafetyNet drop-down is worth addressing. This panel will let you select the hard drive you are backing your data up to. If for some reason you don’t, select the latter option and Carbon Copy Cloner will walk you through selecting what files and folders you wish to exclude from the backup. The first is the way to go if you want a complete clone of your Mac. The drop-down menu offers two options: Copy All Files and Copy Some Files. After clicking the + button in the sidebar, the interface shows three steps:Īssuming you are backing up your Mac’s internal SSD or hard drive, select Macintosh HD. Creating a BackupĬreating a new backup task is pretty straightforward, but Carbon Copy Cloner offers a lot of customization. Unlike some nerdy utilities, Carbon Copy Cloner’s user interface is easy to use and understand. We recommend one that is similar - if not the same - as your Time Machine drive for convenience, but just about anything will do as long as it’s equal to or larger in capacity than your boot drive.) (Obviously, you’re going to need a hard drive dedicated for this. Moreover, there are some advantages to having a bootable backup of your Mac. It’s an excellent way to diversify your backups beyond Time Machine. ![]() The best way to make bootable backups of your Mac is Carbon Copy Cloner. Simply plug in the drive, boot your Mac with the option key held down, and boom - you’re off to the races. Bootable backups can be great for quick turn-arounds in the case of a failed or replaced disk. Primarily, a Time Machine drive cannot be plugged in and booted from. The utility’s archiving ability is extremely useful, but on the recovery end of things, Time Machine isn’t as flexible as power users may require their backup solution be. You can just get back to a working setup faster with the other solutions.and TM has messed up for some people before so it's nice just having another backup just in case.MacOS’ built-in Time Machine is a fantastic way to easily back up a Mac, but it has its limitations. With Time Machine you have to boot from the OS X disc (imaged onto a flash drive in my case for easy access) and restore to a blank drive. You can do that with Time Machine or disk images. Drawback with this setup is that you can't do multiple system backups onto one drive of course. When I replace the other drive I can restore back then continue my old setup. In my case if my main drive dies, I can remove it and boot off the backup and continue whatever I was doing. With a cloned disk you can do the same type of fast block copy to restore, but the big thing is to be able to have a bootable backup. ![]() The basic things are that with an image you can restore faster since I think it can just write straight blocks of data out rather than at the files level (this can be done with Disk Utility too, but it's not meant for incremental backups).
