What is System Backup?
A System Backup involves all of the system files, boot files, and program files. Backing up both the system and boot files can ensure that the operating system works normally when we restore the operating system. 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 the system partition and the boot partition are.
System partition: the partition that installs the operating system, applications, and saves your personal files. That is the so-called C Drive. System files require relatively more space. For example, the system files of Windows 7 require at least 8 GB.
Boot partition: the partition that stores boot files, including boot.ini, ntldr, bcd, winload.exe, etc. Boot files require relatively less space, generally less than 200MB.
Before the introduction of Windows 7, the earlier operating systems such as Windows XP, Vista, as well as Windows Server 2003, had the system and boot partitions combined together. That is to say, the boot partition was a system partition and the system partition was a boot partition. Thus, with those earlier operating systems, we just need to backup one partition during system backup.
In Windows 7 and later operating systems, the system partition and boot partition are usually separated. The System partition is the C Drive that can be accessed normally, while the boot partition is a 200MB or bigger partition, named "System Reserved Partition". The boot partition usually does not have a drive letter, and we cannot access it in Windows Explorer. When backing up Windows 7/8/8.1/10 OS, we should backup these two partitions to complete a system backup.
Fortunately, the PC system backup software - AOMEI Backupper Professional has provided the specially designed function of "System Backup", which can automatically back up both of these two partitions. In addition, during system restore, it will automatically restore the backed up files to two respective partitions. It offers us one-key operations of system backup & restore.
Why is a Regular System Backup Needed?
In general, when the operating system has been used for a period of time, most users would face the problem of system crash, as well as many other disk problems that prevent the system from working normally. In such cases, reinstalling the operating system is one available solution. As known to many people, OS reinstallation is time-consuming. It requires at least half an hour at a time. And then it can take many hours to install various drivers and applications.
To save a lot of time and effort, we can do a complete backup of the system (usually C Drive) immediately after the installation of a new operating system and some commonly-used applications. It is wise to do a full system backup at intervals no matter how old the computer is. Thus, if there is any system problem, the system can be restored to the previous normal state quickly with the backup image file.
Tips: Before backup, you had better do a system cleaning and delete some useless temporary files. Because the more applications installed on system drive are, the bigger the image file will be and the more space the image file will take. What’s more, there’s no need to restore useless files in the future.
System Backup by using AOMEI Backupper
AOMEI Backupper provides a one-key function of system backup for Windows 7/8/8.1/10 and other common Windows PC operating systems. It can backup system and boot partitions to an image file conveniently. Meanwhile, it possesses the function of compression which can reduce the storage space required by the image file to the largest extent.
It also provides advanced level users with the function of incremental and differential backup so as to improve the backup efficiency and further reduce the storage space required by the image file. The steps of AOMEI system backup and restore process are as follows:
Good to Know: The program files and personal data (like photos, music, documents, etc) in C drive are also backed up along with system backup.
1. Download AOMEI Backupper, install and launch it. Then, click "System Backup" under the "Backup" tab.
2. Modify the “Task Name” so that you can distinguish it from other backup tasks. The system and boot drives have been selected as source partitions automatically by AOMEI Backupper. Select a destination path (local disk, external drive, network share, NAS, cloud drive, etc) to save the system image file.
3. Click "Start Backup" to begin system backup.
"Backup Options": it can be set based on your own needs. It includes the functions of adding comments for system backup to distinguish it from other backups, compressing, encrypting and splitting image file, etc.
"Schedule": to make sure your system backup is up-to-date, you can create schedules to backup system automatically.
3. Click "Finish" option to exit. You can tick the box before "Check backup integrity on completion" to make sure the system backup image is valid for restore. You also can choose what you need your computer to do after system backup is completed, such as shutdown, restart, etc.
In addition, the operations of system backup will not interrupt your work. That is to say, you can do system backup while working on the computer. The time for system backup is determined by the amount of the valid data. More valid data costs more time to do system backup.
How to Do System Restore?
AOMEI Backupper provides different methods for you to restore system backup.
If your system crashes or disk fails, you can create a bootable media to restore system backup.
If you buy a new computer, you can use "Dissimilar Hardware Restore" with a bootable media.
If you just want to restore individual files or folders, you can mount the system backup as virtual partitions with "Explore Image".
If you are a system admin or service provider who manages and maintains a large batch of computers, AOMEI Image Deploy enables you to restore system image to multiple computers simultaneously over network.
