Backup of important data

(1) backing up important system data
Data in key areas such as partition tables, primary boot areas, and boot areas is related to the safety of the entire system. In general, we can use kv3000 and repair
　　 (2) Registry backup
The Registry is a central database used by windows to store hardware configurations and software settings. It plays a vital role in the normal operation of the system and its software, because applications and hardware configurations often modify the registry and add content to it, the Registry is more prone to errors or damage than other static files on the computer. Therefore, it is necessary to back up the registry.
Although the Registry is logically a database, the system physically divides it into two files for ease of management and use: User. dat (user setting) and system. dat (system setting ). Therefore, there are many methods to back up and restore the registry:
After windows is started, the two registry files are automatically backed up: User. dat is automatically backed up to user. Dao, and system. dat is automatically backed up to system. Dao. If the Windows registry is damaged after you open the computer, you can restart the computer, enter the pure DOS, and find user. da0 and system. da0, and overwrite user. dat and system. dat with them.
Due to the importance of the registry, the Windows system also backs up the system files after the last five days in the cab file format in the C:/Windows/sysbckup directory. The backup file names are rb000.cab, rb001.cab, rb002.cab, rb003.cab, and rb005.cab. The cab package contains user. dat, system. dat, system. ini, win. ini, and other system files. To extract the corresponding system files from five cabin files, use the scanreg.exe Command provided by windows to enter the pure DOS mode. Run the scanreg command at the DOS prompt. Click the start button to check the core system files. When everything is normal, the next operation interface is displayed. By view backups ...... Scanreg will display the Registry backup file in C:/Windows/sysbckup. Select a cab package and click "Restore" to restore it, then, click "OK" to restart the computer. The damaged registry is restored to normal.
In addition, the Windows 9x CD-Rom installation disk contains a program that can create nine backups for the Registry: cfgback.exe. To create a sequence, double-click cfgbck.exe and follow the detailed prompts. Of course, you can also manually back up the two files in the registry. You only need to note that the attribute is "implicit, system" and must be processed during copy.

1. First, back up the relevant parts of the registry:
Run the regedit.exe file, open the Registry Editor, and find the "hkey-crrrent-user/software = Microsoft/Internet accountmanager/Accounts" Branch, which has the following: 00000001, 000a, and other sub-keys (depending on the number of mailboxes and newsgroups) represent your mailbox and newsgroup respectively. Click Accounts primary key, select the "Export Registry File" command in the "Registry" menu to export and save the registry of the subkeys under the key.
2. Back up directory files.
Back up all information in the application data/Microsoft/Outlook directory under the Windows Installation Directory (that is, all information in the folder that is prompted when Outlook Express is run for the first time ), if your Windows is a multi-user configuration, you must back up the corresponding information in the Windows/profiles directory.
3. Backup file recovery
After the Windows system is reinstalled, you should re-set the mailbox and newsgroup account in Outlook Express. The specific steps are as follows: Run regedit to import the previously exported registry file to the registry; restore all the previously backed up information files and directories to the same path, and then run Outlook Express again, you will find that all emails, newsgroup directories, and all the pre-defined newsgroup files you have received are in good condition.

After using Foxmail for the first time, the software will automatically create a subdirectory named mail under its installation directory. It stores the emails you have received and sent. You only need to copy the mail directory to a backup directory to complete the backup operation.
　　 (5) ICQ Data Backup
You can use ICQ embedded backup tool: ICQ message archive. Open the ICQ program window, click "seruices" at the bottom to bring up the information management menu, and select "message Archive"/"Open message Archive". The ICQ message archive window is opened, we can start the backup. We should focus on backing up information and address books.
1. Back up messages (historical data)
Historical data is an automatic record library that transfers all the information since ICQ is used. There are often important materials that need to be backed up. After selecting the backup part in the directory tree, click "file/Save as" on the menu bar. In the displayed dialog box, enter the file name and select the storage path, it is automatically backed up as a text file.
2. Back up Address Book (address data)
Address data is an address book that contains important information such as the address and personal information of ICQ friends. After you back up the data, you can find a large number of ICQ numbers after reinstalling ICQ. The backup process is simple: Select "Address Book", then select "file/export Address Book" (export Address Book) on the menu bar, enter the file name in the dialog box, and select the storage path, in this way, the backup is complete. After you reinstall ICQ, you only need to enter "ICQ message Archive". In the "file" menu, select "Import Address Book" (introduce Address Book ), in the pop-up dialog box, select the previous backup file. After confirmation, you can find that all friends in the ICQ address book are back.
However, I personally think that the simplest way to back up ICQ or OICQ data is to back up the entire installation folder. All information will be returned after registration.
