How to restore a backup?
There are several ways to restore the operating system after a crash. You can make an installation backup disk, you can create a disk image with Windows stored on it, you can use various utilities - there are many ways. The effectiveness of each individual. But in all these methods are similar, namely in creating a preliminary backup, with which you can restore the OS. There are several ways to restore a backup. And each has its own nuances.
Restore from registry backup
This method of system recovery is suitable when it does not go to restore Windows with the help of self-created restore points or when the system is turned off. In this case, you will need a backup copy of the registry created by the system every ten days, with the “Task Scheduler” enabled. The Task Scheduler is an MMC equipment that allows you to specify tasks that will be automatically executed, to run tasks at a specified time, or after certain events occur.The Task Scheduler contains a library of all the tasks that have been assigned. At the same time there is an option to manage tasks and convenient quick viewing. From this library, you can run, disable, modify and delete specific tasks:
- Before you restore a backup, you need to make sure that you have a backup copy of the registry. To do this, go to the “Start” menu, the “Control Panel” tab, where you can open the “Administration” section. There select "Task Scheduler".
- Next you need to open the library scheduler, to do this, go to "Microsoft", select "Windows" and specify "Registry". There is a copy of the registry. The main files are located on the C drive in the “Windows”, “System32” section. Where is the folder "config" with the nested "RegBack".
- Since you cannot restore Windows backup without auxiliary utilities, in this case you need to use Windows RE, the recovery environment.
- You need to download data from the system recovery disk or the installation disk. After that, you need to open a line of commands. In the field, you must enter the command "notepad" and press the "Enter" key.
- In the notepad dialog box, select the “File” tab and click “Open”.Then you need to open the file "config" from the C drive from the Windows folder, "System32".
- Then in the "File Name" field, enter an asterisk and click "Open." Now you can see, without extensions, all hidden files that are registry branches. After that, the file “SOFTWARE” needs to be renamed to “software.bad”, and the file “SYSTEM” should be renamed to “system.bad”.
- You need to open the “RegBack” folder, find the “Filename” field there, enter a star there and click “Open”. Now you need to copy the “SOFTWARE” file to this “RegBack” folder and paste it into the “config” folder.
- Do the same procedure with the file "SYSTEM". It needs to be copied from the RegBack folder and pasted into the config folder. After all you need to restart the computer.
System restore from image
Before restoring a backup, Windows must first be saved to a backup file on any media. Also, this file, if necessary, will be used for full system recovery. You can make a copy using different programs - BackItUp Image Tool, Windows NT Backup-Restore, Acronis True Image, etc. As a backup media, it is better to use a large flash drive or hard drive. By the way, the hard drive can be both external and internal. You can use the hard drive on which this OS is located, if the disk is divided at least into a couple of logical drives.Although it is worth knowing that the location of the backup file and directly on the same hard drive will double the recovery time.
DVD discs are rarely used as carriers, since the size of a system copy is usually the size of several discs. Creating a backup on multiple disks is very inefficient. These discs need to be inserted several times, following a certain sequence. In addition, the recording and installation of each disc takes a lot of time. But if the backup copy of the system fits on 2 or 3 DVD discs, then you can pick up the optical media. Although, there are nuances:
- If the system will be copied to the hard disk on which it is located, then the backup file must be placed on another partition of the hard disk. Do not be afraid that the file size of the copy of the OS will take up a lot of space.
- Since you will need to restore the backup from the disk, you need to remember that the size of the backup copy is equal to the total size of the files, not the size of the system disk. Ie, if you have only one hard drive, then before restoring the system, it must be divided into two disks - archive and system.
- So, then a backup copy of the system can be placed on the archive disk. You should not try to share the main partition of the disk with the operating system already installed. There is also no need to divide additional partitions of the disk if there are at least some files there.
- You need to open the recovery program and in the window you need to select the option "Restore". You need to select the backup file as the source. At this stage, the program will find all backup files itself, although this can be done manually.
- You need to select a partition with an inoperable Windows. And be sure to tick off the option “Master MBR”. If you do not check this box, Windows recovery will be impossible. The check mark is not installed by default.
- The recovery process usually takes from 5 to 30 minutes or more. Recovery time will depend on the size of the system and the type of media on which the backup is located. If the backup is stored on a second hard drive, the process will take two times less time than if the installation will be done from one hard drive.
