Cautions on backing up data with Time Machine

For most MAC users, the most common data backup solution is to use built-in Time Machine tool. It is indeed a very good backup solution. Its work theory is that after users boot Time Machine for first time, the software copies data of the whole disk. And after each hour, Time Machine will exchange check the File system Events (FSEvents) in MAC OS X system to see whether change happens in system. If there are some changes, Time Machine will back up the changed files. Some friends may think that if Time Machine keeps operating backup operations, much of our storage space will be occupied. Considering this problem, Time Machine has also specially designed. Every week, it will automatically wipe the data backed up in last week. Thus, it not only saves space, but also keeps a set of complete system backup.      

Certainly, there is other data backup method in MAC computer, for example, the tool bar of Finder has backup function. However, this backup function has great limit. For example, we use Finder’s backup function to back up the data in a hard disk which can be used to boot to another hard disk, but we still can’t gain a system that can be booted. Besides this, maybe some friends also back up by using disk tool to make image. Although this image function allows users to make the whole hard disk as image and store it to other disks or shared volumes, the image we make is just a file or a special file package. Although when encountering system paralysis, we can use this image to copy system to the state that we are making image, we can’t immediately boot the system. It is because the system recovery will cost a long time.      

The common MAC Backup methods are introduced above, so I don’t introduce other backup operations (such as Apple backup, Unix system commend and MAC system commend) one by one. In fact, the users who have used data backup should know the superiority of Time Machine, for instance, after Time Machine copy the whole disk for first time, it will automatically performs to save time for us. Secondly, Time Machine just visits FSEvents, but not need to scan hard disk, and use less system resource when backing up. There are Time Machine’s superiorities.     

But when we use Time Machine, we should pay attention t to some things, for instance, we’d better boot Time Machine to back up as soon as we install the system. Since there is little content after install the system, we can save much time. Besides, because Time Machine regularly back up the system changes, if we create files during the backup pause, data loss may occurs, but Time Machine can’t recover your lost data. At this time, to recover lost data, we need to use the indicated MAC data recovery software MiniTool MAC Data Recovery to recover lost data. After that, Time Machine can back up the file.  

I believe, as long as you use Time Machine to back up data, you should own MAC data recovery software like MiniTool Mac Data Recovery. By this, data loss disaster will not cause any losses to you. It is really important for you to do the protection work.
