Top 10 backups that must be performed before reinstalling the system

Computer shop news Even if it is the most stable operating system, WinXP will be caused by various natural disasters such as software damage, virus attack, hacker harassment, or even ourselves. The danger of a misoperation that caused a crash threatens us at all times. After the system crashes or a major error occurs, the best way is to reinstall the system. However, what should we do first before reinstalling? You will definitely say: “Backup!” However, which ones should we back up? What is the thing? First, backup hard disk data Hard disk data includes the main boot sector, operating system boot sector, FAT table, DIR table, etc. This is the basis for the normal startup of the computer system, therefore, timely backup of the hard disk data is the first thing. For the backup of hard disk data, the best method is anti-virus software. It is recommended to use “Rising” anti-virus software, because it can not only backup the above hard disk data, but also allow users to set the time for automatic backup. Open the “Rising Stars” main interface, click the “Settings” button, select “Options”, and then click the “Hard Disk Backup (B)” button to set the way to back up the hard disk data. In the future, “Rising” will automatically back up the hard drive data according to the method you set. If there is no "Rising", then you can also use KV3000 to back up. After typing the KV3000/B command at the DOS command prompt, the system will output two virus-free hard disk master boot information files to the floppy disk, namely HDPT.DAT and HFBOOT.DAT, these two files are the partition table of the hard disk and the information of the master boot record. Note: The backup hard disk data is only valid for the current hard disk partition status. If the hard disk is repartitioned or the partition size is adjusted later, it should be backed up. Second, the backup registry The registry stores all the settings of the computer and the registration information of various software and hardware, so its importance is self-evident, so timely backup of the registry is an extremely important task. The backup method is very simple, just enter “Regedit” in the "Run” dialog box and press Enter, then select “Export" under the "Registry" menu in “Registry Editor” The command will do, of course, don't forget to store this backup registry file in a non-system partition. Or directly copy the User.dat and System.dat files in the C:\\Windows directory to achieve the purpose of backing up the registry. Third, the backup driver After reinstalling the WinXP system, you need to install a variety of hardware drivers, and find and install a variety of graphics cards, sound card drivers is a big problem, if you lose the driver CD, it will make us anxious Like "the ants on the hot pot" in general. At this point, "Driver Backup Expert" can help us solve this problem, it can quickly detect all hardware devices in the computer, extract and backup the drivers of the hardware devices. It also comes with an INF script installer that simplifies the installation of hardware devices, and these extracted drivers come in handy when we need to reinstall WinXP. “Driver Backup Expert” operation is very simple, just click on the “Quick Collection” button in its main interface, select a hardware device and click the “Backup” button to specify the storage path of the backup file. And the file name, click the “Start” button on the line. And if you want to back up all the drivers more quickly, you can click the "Quickly Collect" & "Backup All" button so that all drivers in the system will be "clone". Need to be reminded that during the backup of all drivers, please do not press any keys or buttons. Fourth, backup mail account Many online friends have multiple mail accounts, for their backup work, we can use the registry, in the registry, expand to the HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Account Manager\\Accounts branch, if There are five mail accounts in OE, then there will be five subkeys of 00000001~00000005 under the Accounts button. Click the &aposquo;Accounts button, select the “Registry-Export" command in the menu, select “Select Branch> in the "Export Range", enter the backup file name, press the “OK” button They can be backed up. Backing up personal data Undoubtedly, personal data is the most important data for computer users. It includes personal files, downloaded materials, personal emails, OICQ or ICQ data. For the backup of personal files and downloaded materials, we only need to copy them to the non-system partition of the hard disk or burn to the CD and other places. For the backup of personal mail, if you are using Outlook Express, then you should ""C:\\Documents and Settings\\User name\\Local Settings\\Application Data\\Identities\\{number string}\\Microsoft\\Outlook Express\\ ” In the directory "Inbox.dbx" and "Outbox.dbx"; two files are copied to the non-system area. Of course, it's best to customize the mail location to other places. The specific steps are: Click “Tools”-“Options”-“Maintain”-“Storage Folder”, Change to the mail directory you want to back up. For backup Foxmail mail, it is relatively simple, just copy the files in the Mail subdirectory under the Foxmail installation directory to the non-system area. OICQ and ICQ backup: For OICQ, chat records and personal information are stored locally. The easiest way is to copy the OICQ installation folder to the subfolder with the same name as your OICQ number. Of course, you can also use the "Import" function provided by OICQ to back up your chat history. ICQ is different from OICQ. ICQ does not save the buddy list in the server, but saves it on the client. Therefore, after reinstalling the system, not only must you repeatedly type your ICQ number and password, but also re-enter your friends. Their ICQ numbers are searched and waiting for their confirmation, the operation is extremely cumbersome. Therefore, we should use third-party software to complete the backup work. Here, we recommend ICQ Rescue, a free software that specializes in backing up ICQ. It is very simple to use and has detailed tips. The specific operation will not be said. Download address: http://www.skycn.com/soft/744.html, the size is only 109KB. Backup Address Book For the backup of the address book, simply copy the files in C:\\Documents and Settings\\username\\Application Data\\Microsoft\\Address Book to the non-system area. Of course, we can also back up through the mail software itself, such as the OE address book, which can be backed up by “File-Import-Address Book”; for the Foxmail Address Book, it can pass its “Address Book”. The "Export-Web File" command under the "Tools" menu in the window is used for backup. Seven, backup mail rules and personalized signatures Customized mail rules can effectively prevent spam, these rules can be set offline, therefore, the backup of mail rules is also a very important job. Backup of mail rules can be found by means of the Registry Editor, HKEY_CURRNT_USER\\Identities\\{77BEB813-E85F-411A-9704-CA8F14492CC2}\\Software\\Microsoft\\Outlook Express\\5.0\\Rules\\Mail, which holds the mail rule settings Of course, the user is different, then the data in the braces will be different, the Mail primary key is exported, you can complete the backup of the mail rules. Personalized signatures can be implemented in two different ways, one is text mode, which is typed directly in OE, and the other is file mode, which specifies a file as a signature and attached to the end of the message. For the latter, backup is naturally very simple. The backup of the former needs to operate in the registry. The personalized signature is located in the Signatures key value item under the 5.0 primary key in the registry, and the exported Signatures also backs up the personalized signature. 8. Backing up IE favorites BOOKMARKS in the IE Favorites stores many URL links in the X:\\Documents and Settings\\username\\Favorites\\ directory, copy them to complete the backup work, and when the system is reinstalled Then copy it to the original directory to complete the recovery. In addition, we can also use IE's "export" function, change the favorite storage path to achieve backup. Use IE's "Export" function: When you have finished sorting your favorites, select the "Import and Export" command under the IE“Files" menu, click the “Next” button and select “ Favorites & rdquo; items, click the “ next & rdquo; button, and then follow the prompts to enter the path and file name of the backup file. Change the favorite storage path: Expand to the HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell Folders branch in the Registry Editor, find the “Favorites” key-value item in the right window, double-click it, in “ In the data value & rdquo; enter “ E: \\ favorites & rdquo; In this way, the contents of the favorites are stored in the E area (if the E area is a non-system area). Nine, backup custom phrases In normal times, in order to enter phrases more conveniently and quickly, we often define some phrases ourselves, but once the system crashes, these custom phrases will also be "sacrifice", then we will They should be backed up for reuse after reinstalling the system. In the C:\\Windows\\System32\\ folder, the three files Wbx.emb, tmmr.rem, and pXXXp.upt correspond to the custom phrases of the five input methods, smart pinyin, and Microsoft Pinyin (the XXX is Just enter the username you entered when you logged in to the system and copy them out. In addition, for hand-made words, you can use its "Featured Menu" in the "Features Menu" to bring the "export" " . If you are not sure, you can copy the input method files in the C:\\Windows\\System32\\ folder directly. Ten, backup system partition Backup system partition, one is to use Ghost to backup the entire system disk, another method is to use WinXP's own "system restore" function to back up. These methods and the issues that should be noted are described in the forum posts, so I won't go into details here. With the backup work of all the above aspects, I believe that the majority of computer users will never "stunned" in the "system crash"! For the security of the system, and for everyone's efforts, please do Good data backup work, take precautions and prevent problems.
