Data is one of the most important assets of an enterprise in the information age, and the normal business of an enterprise relies on corresponding data. Data loss and damage may lead to the interruption of the company's normal business, causing economic and intangible asset losses to the company.
Moreover, with the continuous development of information applications in small and medium-sized enterprises, business-related data is not only stored in enterprise servers, but also part of the data will stay in workstations, laptops and other devices on the network. Therefore, how to properly protect the data in these devices is one of the key issues that small and medium-sized enterprises must solve. Application data backup is the main way to solve data security problems.
For current small and medium-sized enterprises, since the main direction is to vigorously strengthen production and operation, it is impossible to invest too much manpower and material resources in IT, so it is impossible to have a strong technical force to implement data backup. . What current small and medium-sized enterprises need is a backup server that is cheap, easy to deploy, easy to use and manage, and supports multiple backup methods to provide a unified backup interface for all backup tasks.
So, is there any way that we can have a backup server that meets the enterprise's data backup needs and meets the enterprise's cost budget for data backup? One of the best practices is to use free backup software to build a high-performance enterprise-level backup server yourself.
In this article, I will assume that there is a network structure as shown in Figure 1. The server and all workstations in the network are using the Windows XP operating system. Now you need to back up the "e:ywdoc" directory on the file server "fileserver" in this network and the "f:mydoc" directory on the workstation "work1" to the network storage server NAS1 installed in the network. corresponding directory.
And established a corresponding backup and recovery plan according to the method shown above: the "e:ywdoc" directory on the file server should be fully backed up once a week, and the file name should be stored on the network storage server NAS1 with the backup date. e:fileserverfull" directory, the specific backup time is Sunday at nine o'clock in the evening; this directory on the file server should also be incrementally backed up every day. The incremental backup execution time is automatically performed by the backup server and backed up to In the "e:fileserverincre" directory of the network storage server NAS1.
The "f:mydoc" directory on the workstation "work1" is fully backed up once a month. The backup file is stored in the "f:work1full" directory on the network storage server NAS1 with the date as the file name. The specific backup time is every month. The work is completed manually at the end of the last day of the month; however, the corresponding incremental backup must be performed every day, and the backed up files are saved to the "f:work1incre" directory of the network storage server NAS1 with the name of the backup time.

1. Selection of backup software
Now, we already know the data backup tasks that need to be completed in the example of this article. Next, we have to choose a suitable backup software for this and use it to build a backup server to complete the data given in the example of this article. Backup tasks.
Currently, among the many free data backup software on the market, Cobian Backup 9 is the most suitable backup software for the data backup needs of most small and medium-sized enterprises in my country. This is because Cobian Backup 9 is not only a free multi-threaded file backup program, but you can also use it to backup files and directories to other computers in the network or to dedicated storage servers in a planned manner. Cobian Backup 9 can perform full, incremental, and differential backup of files and directories; it can set automatic backup plans by year, month, day, week, and time; it can back up files or directories to FTP sites, or Back up files on the FTP site to another location.
It also provides four encryption methods to encrypt backup files. These encryption methods include: RSA-Rijndael (1024bits), BlowFish (128bits), Rijndael (128bits), DES (64bits); and you can use zip64 and 7zip. Compression method compresses backup files to reduce backup space. We were also able to set passwords to restrict who can use it, as well as set it up to email backup logs to a specified mailbox.
In view of the fact that most of the computers used by small and medium-sized enterprises in my country currently run Windows operating systems, in this article I will use Cobian Backup 9 backup software to create a backup server, which can only back up Windows2000/XP/2003/vista operating systems. files and directories on your computer. We can download the installation file of Cobian Backup 9 from http://www.cobiansoft.com/cobianbackup.htm. It is an executable file named "cbSetup.exe". The total size of this installation file is only 9.15MB.

2. Hardware requirements
For the Cobian Backup 9 backup software we just selected, in principle, it only requires an ordinary computer that can run Windows XP system. However, for small and medium-sized enterprises, if a large amount of data needs to be backed up, it is necessary to use some high-performance and high-quality PC hardware to ensure that all backup tasks are completed in a timely and efficient manner. Usually, the main hardware of the backup server can meet the following requirements to meet most backup tasks:
CPU frequency: Pentium 4 2.0GHZ and above.
Memory: DDR667 1G and above.
Disk space: It can be a hard disk with an ordinary IDE or SATA interface, as long as there is 40G of remaining space on the disk.
Network card: 100/1000Mbps Ethernet network card. If you do not use load balancing, you only need one.
For data backup, while determining the backup server hardware, we must also decide what storage media to use to save these backup files. Nowadays, the price of disks is getting lower and lower, while the single capacity of hard disks is getting higher and higher. Coupled with the use of SATA interface, no matter in terms of price or speed, using disks as a storage medium for backup files is an important choice for small and medium-sized enterprises. first choice. At present, there are many small and medium-sized enterprise network storage servers with terabyte capacity on the market, and their use can fully meet the data backup needs of most small and medium-sized enterprises that are currently in their infancy or growth stage. However, before selecting a specific storage server, the current total capacity of the storage server and future expansion methods should be determined based on the actual backup data volume and growth. Moreover, in order to ensure the security of backup files stored on the storage server, it is best to choose a backup storage server that uses dual power supplies and supports RAID and hard disk hot swapping.

3. Software installation and configuration
What needs to be done now is to install the Cobian Backup 9 backup software as a server on the file server "fileserver" in the network structure given above in this article, and then complete some basic settings before performing the backup tasks given in the example in this article. .
1. Install Cobian Backup 9
The installation of Cobian Backup 9 is very simple. In Windows XP system, just run the downloaded cbSetup.exe file to start its installation process. Since it provides support for Traditional Chinese, we can select "ENGLISH" when selecting its installation language. As for the location where the installation file is saved, I usually install it to a partition other than the C drive.
When the installation process reaches the stage of selecting the installation type as shown in Figure 2, select "As a service" in the "Installation type" area to install it in server mode, and then select "Use the local system account" in the "Logon options" area. "Log in using the local system account, and make sure "Autostart the user interface" is selected, and then click "Next" to start copying the files. After a while, you will be prompted that the file installation is complete. In the interface that appears, click " Done" button completes the entire installation process of Cobian Backup 9.
Figure 2
After completing the installation of Cobian Backup 9, since we chose to run it in server mode, it will run automatically when we restart the system. Cobian Backup 9 will not directly display its main interface after running. It only displays a mushroom icon in the tray area in the lower right corner of the system desktop. Double-click the mushroom icon to display the main interface as shown in Figure 3.

2. Complete the basic settings of the software
Before starting to use Cobian Backup 9 for file backup, we must first complete some basic settings of the software so that it can better complete various backup tasks in the way we set. To complete these basic software settings, you can click "Tools" - "Options" menu on the main interface of Cobian Backup 9 to open the "Options" menu setting interface as shown in Figure 4. It should be noted that the settings completed in this option setting interface will affect all backup tasks.
Figure 4
In the options menu setting interface, we can reset the language used by the software and specify the temporary folder in the "General" tab; if you want to set it to send backup logs to a specified email address, you can first select "mail log" in the "Log" tab file" multiple options, and then specify the email address, subject, etc. in the "Smtp" tab; if we want to set a password for using Cobian Backup 9, we can click the "Security" tab in the options menu setting interface, as shown in the figure Select the "portect the user interface" multi-option item in the interface shown in 5, then enter the password in the "password" text box, enter the password again in the "password(retype)" text box, and then select "protect the main window" "You can set passwords for the interface and startup software. We can also set the corresponding secure connection options for remote control in this interface.
Figure 5
We can also click the "compression" label in the options menu setting interface to set the backup compression method in the interface shown in Figure 6. Other settings tabs in this interface can also be used to set various functions used during backup and viewing methods.

4. Implement data backup tasks
After completing all the basic software settings of the Cobian Backup 9 backup server, we can begin to implement the backup tasks given in the examples in this article.
Start Cobian Backup 9, open the "Task" - "New task" menu items in its main interface, and the Create New Backup Task dialog box as shown in Figure 7 will appear. In this example of this article, I will only describe how to create an incremental and full backup task named "serverdaybackup" and "serverweekbackup" for the "e:ywdoc" directory on the file server "Fileserver". As for the workstation " The creation of incremental and full backup tasks for the "f:mydoc" directory on "work1" can be completed by referring to the file server backup task creation method.
Figure 7
1. Create the "serverdaybackup" incremental backup task of the file server
First enter the "General" tab interface of the Cobian Backup 9 create new task interface. Enter the backup name of "serverdaybackup" in the "Task Name" text box in this interface. In the "Backup type" area, specify "Incremental() for the backup task. Incremental)" backup. Other settings can be kept as default. After the setting is completed, it is shown in Figure 8.
Figure 8
Then click the "Files" tab in the create new task interface. In the "Source" option box area of the interface as shown in Figure 5.3, click the "Add" button below it. In the Add Backup File dialog box that appears Select the "e:ywdoc" directory, then click the "Add" button under the "Destination" option box area, and specify the location to which this file is to be backed up in the pop-up dialog box. In this article, after the network storage server used is installed, it will appear in the server's resource manager like a local disk, so you only need to specify the partition path here.
Then click the "Schedule" tab in the create new backup task interface. In the "Schedule Type" combo box that appears, select the "timer" item for this incremental backup task, and then in the "timer (minutes)" text box Enter "60", which means incremental backups will be performed every hour.
If you need to compress the backed up files, we can also click the "Archive" tab in the create new backup task interface. In the "Compression method" drop-down box in the "Compression" area of this interface, specify a compression method for the backup task, such as 7Zip; after selecting the "passwork protect" multi-option, enter the set value in the "password" text box Password, enter the password again in the "password(retype)" text box.
Then in the "Encryption type" drop-down box in the "Strong encryption" area, specify the encryption method for this backup task, such as DES (64bits).
After completing all the settings shown above, press the "ok" button in the Create New Task dialog box to complete the creation of the "serverdaybackup" incremental backup task.
2. Create the "serverweekbackup" full backup task of the file server
When creating a full backup task for a file server, in addition to the name of the backup task and the location where the backup file is saved, the execution time of the full backup should be staggered with the incremental backup in the "Schedule" tab. In this article I set the full backup to be executed at nine o'clock on Sunday night according to the given task. Figure 9 shows the full backup execution time setting interface. The other settings are exactly the same as those of the incremental backup task, so they will not be described again here.
Figure 9
After the creation of all backup tasks is completed, they will automatically perform backup work according to the date or time set in the "Schedule" tab. When the corresponding backup tasks are completed, Cobian Backup 9 will send the corresponding backup logs to the settings in the mailbox. We can also start a backup task immediately by clicking the "Start All Tasks" or "Start Selected Task" button in the toolbar of its main interface. Of course, after creating a backup task, we can also view and modify it by double-clicking the backup task in the task list of the Cobian Backup 9 main interface.
The two backup tasks of the workstation can also be set up in the above manner, except that the names of the backups are different so that they can be distinguished well. If there are many more backup tasks than in this example, in order to save network bandwidth during backup, we can stagger the specific backup times of different backup tasks from each other.
To sum up, using Cobian Backup 9 backup software to create a backup server is very easy to install, easy to use and maintain, and can also meet the current data backup needs of most small and medium-sized enterprises. If your small and medium-sized enterprise is looking for a cheap, easy-to-install and manage data backup solution, you may wish to try the methods given in this article, and you may find better results.
