System backup refers to back up all the system files and boot files. Only if backing up both the system and boot files can ensure the operating system work normally when restoring the OS next time. If only one of them has been backed up, the operating system may not work normally after system restoring. Therefore, it is necessary for us to know what system partition boot partition are.
Before the operating system of Windows 7, such as, Windows XP, Vista, as well as Server 2003, the system and boot partitions have been combined together. That is to say, boot partition is system partition; system partition is boot partition. In this case, it only requires to backup one partition during system backup. But in Windows 7 and Windows 8, the system partition and boot partition are separated. System partition is the C Drive that can be accessed normally; while boot partition is a 200MB partition, named "System Reserved Partition". The boot partition does not have drive letter, and usually we can not access this partition or any file on this partition. Therefore, when backing up Windows 7/8/8.1 OS, only backing up these two partitions can be called a complete system backup.
Luckily, free system Backup Software -AOMEI Backupper Standard has provided specially designed function of "System Backup", which can automatically back up both of these two partitions. Meanwhile, during system restore, it will automatically restore the backed up files to these two partitions as well. It is a one-key operation without backing up and restoring these two partitions respectively.
Generally speaking, when the operating system has been used for a period of time, home users would face the problem of system crash, as well as many other disk problems that prevent system from using normally. In this case, it is necessary to reinstall operating system. As known to many people, OS reinstallation is time-consuming. It requires at least half an hour at a time. And then it requires about two hours, even longer installing various drivers and applications. Therefore, we would do a complete backup of the system (usually C Drive) after the installations of the operating system and some commonly-used applications.
Many times, in order to avoid OS reinstallation or system problems, we would do a complete system backup at intervals, be it a new computer or an old one that has been used for two years. Thus, if there is any system problem, the system can be restored to the previous normal state quickly and conveniently by the backed up image file so as to avoid reinstallation of OS and applications.
The software of AOMEI Backupper Standard can back up all the data in the system to an image file. If there is any system problem, we can employ AOMEI Backupper again to restore the operating system via the backed up image file. It can help to save a lot of time.
AOMEI backup software provides a one-key function of system backup, which can back up system and boot partitions to an image file conveniently. Meanwhile, it possesses the function of compression to the image file so as to reduce the storage space required by the image file to the largest extent. It also provides advanced level users with the function of incremental backup so as to improve the backup efficiency and further reduce the storage space required by the image file. Here come the detailed operating steps.
First, download this freeware, install and launch it. Then, click "System Backup" under the "Backup" tab.
Second, the "Task Name" can be set based on personal needs, and the name is helpful for you to distinguish it from others. The system drives have been set as source partitions by default in step 1. Then, select a destination path to save the image file, and then click "Start Backup" to begin the operation.
At last, click "Finish" option to exit.
In addition, the operations of system backup will not interrupt your work. That is to say, you can do system backup while working. The time for system backup is determined by the amount of the valid data. For example, if your system takes up 16GB, it may cost ten minutes to do system backup. If your system only occupies 3GB, it may just need two minutes to complete the system backup.
