Why Should I Perform a Computer Backup?

BACKUP originally meant backup. Some installed software puts things that need to be backed up in this folder, such as drivers, favorites, my documents (picture), Backup computer, Backup computer and desktop. So it's better not to delete. Backup Wizard is a wizard in Windows 2000, Windows XP and Windows .NET Server Backup tools.

Backup computer

backup just backs up the system settings and some software settings

GHOST backs up all the partitions, including the boot files on the partitions and the partition table.

GHOST is a complete backup. Backup is restored after the system is installed and requires system support.

First, the system backup brother-ghost10

The installation wizard of Ghost 10 forcibly installs .Net Framework 1.1, and automatically detects some hardware drivers of the user system, such as optical storage devices and Internet access devices. Because Ghost 10 supports transferring backup image files to the specified network storage space or burning CD-RW, DVD-RW and other optical disc drives to burn to optical discs through the network, all these operations require the support of corresponding hardware.

Click the "Backup Now" link to have Ghost back up your system immediately and set options. First select the "Create a new backup using the following settings" option, then specify the name of the backup job in the "Name" box, set the start time of the backup in the "Start time" box, and select the save location of the backup file in the "Destination" box . There are two other important options: create a recovery point after installing any program, and create a recovery point by backing up immediately. It is recommended to select both options. The first option is to make a backup every time you install a piece of software in the future, so if you find that there is a problem with the new software installed, you can always use the backup program to restore the system to the one before the installation status.

Ghost 10 supports the intelligent cleanup function of image files. Users can manually delete redundant image files in the Optimize Recovery Point Storage dialog box or specify the conditions for automatically deleting image files. For example, set options such as "Automatically delete the oldest image file" or "Prompt when the space occupied by the image file exceeds the specified value".

Acronis True Image for Windows backup

Ghost is currently the most mainstream cloning software, but the cloning part is still completed in a pure DOS interface, and Acronis True Image is a software that can use all the cloning and recovery functions in the Windows environment.

(A), the main function of Acronis True Image software: backup / restore a partition or the entire hard disk data, clone between hard disk and hard disk.

(B), the actual combat hard disk image file:

Step 1: Back up the partition and multiple files. Run the "Acronis True Image" software and click the "Backup" button to back up the most important C drive of the system. The "The entire disk contents or indlidual partition" option creates an image file of the entire hard disk or a separate partition; the "Files and folders" option creates an image file composed of multiple files and folders. Click the "Next" button and select the partition name to be backed up. Select the C drive. Then select the save path and file name of the backup file. Acronis True Image supports many types of backup media, including local hard drives, network drives, CD-R / CD-RW, and ZIP100. The suffix of the saved image file is ".tib".

Step 2: Select the type of backup. To back up the system for the first time, you must click the "Create new full backup archive" item to create a complete backup file. On this basis, when the system changes, you can click the "Create incremental backup" item to create multiple incremental backup files. When the system changes, you can click the "Create differential backup archive" item to create only a backup file of system changes.

Step 3: Set backup options and complete the backup.

Click the "Next" button to enter the default settings, or manually set backup options. The file protection (Archive protection) sets a password for the backup file; the compression level (Compression level) gradually increases from top to bottom, the backup file capacity gradually decreases, and the generated backup file time gradually increases from "Normal" to "Maximum" You can also set the "Archive splitting" item to divide large backup files into multiple small-capacity files to save; "Backup priority": select "Low", the backup speed will be slow, but it will not affect the system Other processes running; select "Normal", the backup speed is normal, but affect other processes running in the system; select "High", the backup speed is fast, but at the expense of other processes running in the system. Finally, enter a file comment and click the "Proceed" button to generate a backup file.

Third, the blue sand hard drive crack

Lansha hard drive crack is very simple and practical, suitable for the majority of rookie-level user groups. Run the software compressed package, there is an executable file inside, double-click it to run to open the main interface of Lanshakuike software. Click the "Hard Disk to Mirror File" button. In the "Clone Hard Disk to Mirror" interface, you can select multiple disk partitions for simultaneous cloning, with an average speed of 1.7G per minute. The famous ghost software can only clone one Hard disk partition. After checking the partitions to be cloned, click the "Next" button. In the compression efficiency interface, three compression algorithms are supported, namely fast compression, default compression and deep compression. They generate image files more and more slowly. But the corresponding compression ratio is getting bigger and bigger, the average speed reaches 800M per minute. The size of the generated image file is getting smaller and smaller. Finally click the "Clone" button to generate an image file of the hard disk.

Fourth, the backup based on the job concept-anybackup

AnyBackup, as a professional data backup software for home and small and medium-sized enterprises, is based on the new concept of job data backup, and proposes a complete solution for system partition, directory, and file backup and recovery. The three powerful features are known as the "Swiss Army Knife for backup data", which guarantees the security and stability of user data to the greatest extent.

Backup data

Click the "New" icon on the shortcut toolbar. In the pop-up "New Backup Job" dialog box, the dialog box displays the basic attributes of the job that needs to be entered: backup data source, backup job name, and specific storage location. The backup data source window is composed of a tree window and a list window. They can display all accessible resources on the local computer and the LAN at the same time. In the tree window, you can browse all the detailed subdirectories by expanding the directory. You can also double-click each item in the list window to expand and browse the subdirectories and file contents of the item. Finally, by selecting the check box to the left of the data item, select the partition, directory, and file to be backed up. After selecting the data to be backed up, enter the backup job name in the backup job name input box, select the backup data destination, and click the "backup" button to start the data backup job in the default "incremental backup" form.

plan

Click the Schedule button to start the job plan. The general running user content is automatically composed of the machine name and the current system login user name by the software. After successfully setting the running user of the job, AnyBackup pops up the system task schedule properties dialog box to schedule a job to run daily, weekly, monthly, or at a specific time (such as when the system starts).

Tip: If the user's operating system is Windows 98, you can only set the run time.

Click the "Options" button, AnyBackup pops up the "New Job Options" dialog box (Figure 15) to modify the general settings of the job, or set other advanced options.

New job options include two tab items, regular and advanced. The settings include backup type, overwrite mode, security settings, file filtering and other functions. Backup types: including five types of backup: full backup, incremental backup, full copy, incremental copy, and merge copy. The default backup type of the software is incremental backup, you can choose the corresponding type according to your needs. When selecting incremental backup and incremental copy, you can click the "Advanced" button to the right of the type selection box to set advanced options for the backup type.

Tip: What the backup type options mean:

Full backup (normal backup): Full backup of the selected data source to the backup archive of the specified destination. Each time it is executed, it will not back up after comparing according to the latest changes, but directly back up all the data to the .ABF backup file.

Incremental backup: The first backup is equivalent to a full backup. The data source is completely backed up to the backup file of the specified destination. After that, only the content of the file changes and new files are backed up each time to avoid the exact same Duplicate backups of files and create a backup catalog for each backup for recovery.

Full copy (copy backup): Similar to the copy operation provided by the Windows system itself, during backup, copy backup can keep your backup data in the original directory structure, but generate a catalog file for AnyBackup to restore.

Incremental copy: The first backup is equivalent to a full copy, and only the files that have changed since the last copy are copied each time.

Merged copy: The first backup is equivalent to a full copy, and only the changed files are copied each time after the execution, and the current backup file is merged with the original backup file into a newest file.

Overwrite mode: The user can choose to append the backup file to the backup archive in the destination, or choose to replace this archive file.

Recover data: You can recover data from a job or from a backup archive.

(1) Recovering data from jobs

Select the job files to be restored in the job list, right-click to select the "Restore" menu item, and select Restore

The target location is "Original Location" by default. Click the "Restore" button to start the restore.

(2) Recovery from archive files

Click the "Open" button on the toolbar and select the backup file to be restored. After the "Restore Job" dialog box appears, select the folder, file and partition to be restored, and click the "Restore" button to start the restoration of the backup file.

Five, dumb backup-GhostGo

Use Ghost software to clone the system, so that if the system encounters an accident in the future, you can quickly restore the system to normal operation. However, in the face of the English-only GHOST interface, those with poor e-text are difficult to operate proficiently, which will often lead to system clone failure. If novices have software assistance such as GhostGo, you can not perform complicated Ghost operation settings under the DOS interface. In the intuitive Windows interface, you can easily complete the system cloning operation according to the wizard, which greatly improves the accuracy of the cloning operation. This ensures the successful completion of the cloning operation.

Installation and interface

Double-click to install the GhostGo software. During the installation process, you are required to enter the installation path of the Ghost program. It is best to select the path of the Ghost2003 program. Only in this way can the main interface of the GhostGo software be opened. In the main interface, there are six function options, which can be used to easily clone the system. Let's take a look at the fool clone of GhostGo software!

Automatically backup partitions

If your computer uses a single hard disk system, you can use GhostGo's "Auto Setup" function to automatically back up important partitions or important folders on the hard disk. If you use multiple hard disks, you cannot enjoy this function Already. When you need to back up files automatically, you must first select the "Automatic settings" option in the main interface, and then click the "Next" button. In the pop-up interface, select the target partitions to be backed up, and then set the backup file settings. Save path and name. If there is not enough space on the hard disk to save the backup file, the GhostGo program will automatically prompt you to remind you.

Then continue to click the "Next" button. In the pop-up setting interface, you can select the target object to be created, for example: click "Create to folder", or click "Create to floppy disk", or click "Create as task template", usually select the "Create to floppy disk" option; then insert a new blank floppy disk in the floppy drive, and then click the "Next" button, GhostGo will automatically create startup information in the blank floppy disk; later Use this floppy disk to reboot the system. When the backup message in Chinese appears on the screen, just click the "Y" button, and the GhostGo program will automatically backup the contents of the specified partition according to your settings.

In the future, if there is a problem with your designated partition, you can quickly restore it.

Using the automatic backup partition function, it is very convenient to automatically back up important partitions or data in systems that cannot enter the DOS environment, such as Windows 2000, Windows XP, and Windows 2003.

Through the introduction above, it can be found that when using the "automatic setting" function to back up the hard disk, more specific backup settings cannot be made, such as: selecting the compression ratio, setting password protection, setting automatic response, and setting the partition format. If you want to make more targeted backup settings for the target partition, you can use the "Detailed Settings" feature to quickly generate an image file.

summary:

Ghost10 has very complete backup and recovery functions, but the huge software volume and higher and higher requirements on the system make it difficult for many users who love it. Some users have to go back and use their familiar Ghost 7.5 backup system. . Acronis True Image, as a software that truly uses all the cloning and recovery functions in the Windows environment, is very similar to Ghost in function and much smaller than ghost. Some users have used it as a substitute for Ghost software. As the name suggests, Lansha Hard Disk Crack provides us with a simple cloning route and fast cloning frequency. The biggest highlight of AnyBackup is the integration of open file backup. Since then, AnyBackup can not only reliably back up file data, but also becomes the only software in the country that can regularly and incrementally backup operating systems in the Windows environment. Have you heard of a ghost server that backs up regular data such as FTP server, My Documents, Firefox, Outlook, IE Favorites, QQ / TM, MSN? No, then AnyBackup software can meet all personal data backup needs. The only regret is that it is incompatible with ghost backup data. I hope that its subsequent versions can achieve its compatibility function. GhostGo is very suitable for rookie users. You can turn complicated Ghost operations into fool-type operations without having to set too many parameters.

In the field of information technology and data management, backup refers to copying the data in the file system or database system; once a disaster or wrong operation occurs, the effective data and normal operation of the system can be easily and timely restored. It is best to make three or more copies of important data and place them in different places to facilitate future retrieval.

Backup type

Full backup, that is, a one-time copy of all files, folders or data in the hard disk or database.

Incremental backup refers to backing up data that has been updated since the last full backup.

Selective backup to back up part of the system.

Cold backup: A backup when the system is down or under maintenance. In this case, the backup data is exactly the same as the data in the system during this period.

Hot backup: A backup of the system under normal operating conditions. In this case, since the data in the system may be updated at any time, the backed up data may have a certain lag relative to the real data of the system.

Various data processing techniques

In the process of implementing backup, various processing can be performed on the data. These different processing methods can improve backup speed, recovery speed, increase data security, and improve the utilization rate of storage media.

Data compression technology (Compression): Through various mechanisms to reduce the size of the backup data in order to occupy less storage space, the compression method is particularly common in tape storage.

Data deduplication technology (De-duplication): When data of multiple similar systems are to be backed up to the same storage device, data needs to be backed up repeatedly, which will generate a lot of redundancy. For example, if there are 20 Windows workstations to be backed up to the same storage device, the backup data can share system files. Only one system file is required on the storage device, which can be used to recover multiple workstations. This technology can be applied at the file level or at the unprocessed data block level. By avoiding the duplication of redundant data, the storage space of the storage device can be greatly saved. Deduplication technology can occur on the server side and is performed before data is backed up to storage. This method can save the storage space and save the bandwidth requirements of the backup data. This type of deduplication is called online instant data processing (inline) ; Deduplication technology can also occur on the storage device side, called background deduplication technology.

Data replication technology (Duplication): During the backup process, data may need to be backed up to a second group of storage devices; by copying the backup data, the backup image can be adjusted to optimize the recovery speed, and the second backup data can be stored On a different backup location, or on a different backup medium.

Data encryption technology (Encryption): For large-capacity removable backup storage media, such as magnetic tape, there is a risk of loss and theft. [1] The above risks can be reduced by encrypting the data, but it also brings other problems: first, the encryption will occupy a large number of CPU processes, which reduces the backup speed; second, after the data is encrypted, it cannot be compressed effectively, For example, data compression technology for some tape drives cannot be implemented. Based on the above reasons, and the redundant data makes it easier to provide decryption analysis, many encryption technologies are compressed before implementation; finally, for the encryption technology to work successfully, it must be considered in conjunction with the overall security policy.

Data buffering technology (Staging): Using data buffering technology, backup data is copied to a buffer disk before it is copied to tape. This operation is called D2D2T, disk-to-disk-to-tape. Data buffering technology (virtual tape library technology) is particularly important in network-based backup systems, because D2D2T technology can alleviate the system's need for backup bandwidth. If other data operations need to be performed in the backup system, the buffer disk can also function as a data center.

You can use the backup wizard to configure, schedule, and perform backups. The backup wizard can choose from the following options:

· Back up all files on the computer where you are running.

· Back up specified files and folders. These files and folders can be located on your local computer or on a shared location on the network.

Back up Active Directory directory service information and the registry on the computer on which the wizard is running. Active Directory can be backed up only on a domain controller.

The wizard then guides you to the designated backup location and other advanced backup options, such as verification, compression, and remote storage programs. You can also plan to back up without any intervention after the user stops working and all files are closed at some point in the future.
