If we talk about backup applications, apart from the native macOS application, Time Machine, we must talk about Carbon Copy Cloner and SuperDuper. Between the two they compete, as Time Machine makes copies but is less configurable than the other two third-party applications.
One of the novelties of the new macOS High Sierra system, only on APFS format disks it is possible to take snapshots of the system, to return to that point if we need it. SuperDuper was the first with the ability to make copies based on these snapshots, but Carbon Copy Cloner was quick to react.
And is that In the Carbon Copy Cloner beta we have the possibility of making copies based on these restore points, known as Snapshots. This function is born with SSDs formatted to APFS in macOS High Sierra, if you have any other configuration, you probably cannot use this function. For those who do not know the concept, it is a photo that is taken from our system, at a certain time. Typically you have snapshots from a few hours ago, at most a couple of days, and therefore it is advisable to make copies with some frequency. Also, until you make copies to an external device, the information will not be saved in case of a problem with the solid memory.
The feature is in the Carbon Copy Cloner 5.1 beta. Each snapshot or snapshots are available for reading only and not for writing. Therefore, the backup at this point is more reliable as it cannot accommodate changes to the collected information. The app lists each snapshot completely and show it in the Finder to see its content. If you want to restore an individual file, just move it to the desired location. On the other hand, you can also restore the entire operating system to a previous point.
You can try Carbon Copy Cloner for 30 days and decide, after this period, buy the application for € 42.
