Data backup isDisaster recoveryThe foundation ofOperation errororsystem failure The process of copying all or part of the data set from the hard disk or array of the application host to other storage media as a result of data loss.Traditional data backup mainly adopts built-in or externalTape driveconductCold backup。However, this method can only prevent operation errors from being caused by others, and its recovery time is also very long.With the continuous development of technology and the massive increase of data, many enterprises begin to use network backup.Network BackupGenerally through professionaldata storage Management softwareIt is realized by combining corresponding hardware and storage devices.[1]
Remote critical data+tape backup.Tape backup data is used, and the production machine sends key data to the backup machine in real time.

LAN backup, LAN Free backup and SAN Server Free backup.LAN backup can be used for all storage types. LAN Free backup and SAN Server Free backup can only be used for storage of SAN architecture.
LAN based backup, traditional backup needs to be installed on each hostTape driveThe LAN backup strategy is used to back up the local system. When the amount of data is not large, centralized backup can be used.A central backup server will be installed on the LAN, and then the application server and workstation will be configured as the client of the backup server.The central backup server accepts the request of the backup agent running on the client computer, and transfers the data to the local area it manages and connects with through the LANTape driveResources.This method provides a centralized and easy to manage backup scheme, and shares it in the networkTape driveResources improve efficiency.[3]
LAN Free BackupBecause the data is spread through the LAN, when the amount of data to be backed up is large and the backup time window is tight, the network is prone to congestion.In SAN environmentstorageNetworkedLAN Free Backup, the server to be backed up is connected to theTape driveOn the LAN Free backup client software, the data to be backed up is read and backed up to the shared tape drive through the SAN.This independent network can not only transfer LAN traffic, but also requires less CPU resources than LAN mode, becauseFibre ChannelThe connection does not need to go through the TCP/IP stack of the server, and error checking of some layers can be completed by the hardware inside Fibre Channel.Need one in many solutionshostTo manage shared storage devices and backup databases for finding and restoring data.SAN Server Free Backup LAN Free Backup pair needs backuphostIf the backup process can be completed within the SAN, and a large number of data streams do not need to flow through the server, the impact of backup operations on the production system can be greatly reduced.SAN Server Free backup is such a technology.

Threats to data are usually difficult to prevent. Once these threats become reality, they will not only destroy data, but also destroy the system accessing data.The main reasons for data loss and destruction are as follows.
2. The design vulnerability of the operating system or the "black hole" artificially preset by the designer for hidden purposes.
3. Hardware failure of the system.
4. Human error in operation.
5. Malicious damage of illegal visitors in the network.
6. Network power supply system failure, etc.
The important data, files or historical records in the computer are vital to both enterprise users and individual users. If they are lost carelessly, they will cause immeasurable losses. At least, the hard work accumulated will be wasted. At worst, they will affect the normal operation of enterprises and cause huge losses to scientific research and production.
In order to ensure the normal operation of production, sales and development, enterprise users should take advanced and effective measures to backup data and prevent it before it happens.

The determination of disaster recovery level is an important consideration in the construction of information system disaster recovery.The Specification divides disaster recovery capability into 6 levels.
Level 1: Basic support.The data backup system is required to ensure data backup at least once a week, and the backup media can be stored off-site.For standbydata processing systemAnd standby network system, no specific requirements.
Level 2: Standby site support.On the basis of meeting the conditions of Grade I, it is required to equip some data processing equipment required for disaster recovery, or deploy the required data processing equipment to the standby site within the scheduled time after the disaster;It is required to equip some communication lines and corresponding network equipment, or deploy the required communication lines and network equipment to the standby site within the scheduled time after the disaster.
Level 3: electronic transmission and equipment support.It is required to back up the full data at least once a day, store the backup media off-site, and regularly and batch transmit the key data to the standby site by using the communication network many times a day.Some data processing equipment, communication lines and corresponding network equipment required for disaster recovery shall be provided.
Level 4: electronic transmission and complete equipment support.On the basis of Level III, it is required to configure all data processing equipment, communication lines and corresponding network equipment required for disaster recovery, and to be ready or running.
Level 5: Real time data transmission and complete equipment support.In addition to full data backup and storage of backup media outside the field at least once a day, it is also required to use remote data replication technology to copy key data to the standby site in real time by using the communication network.
Level 6: Zero data loss and remote cluster support.It is required to realize remote real-time backup and zero data loss;The standby data processing system has the same processing capacity as the production data processing system. The application software is "clustered" and can be switched in real time.
It can be seen that the higher the level of disaster recovery capability, the better the protection effect for information systems, but at the same time, the cost will rise sharply.Therefore, in the construction of disaster recovery, how to determine the reasonable disaster recovery level of the business system is a major problem.It is also pointed out in the Specification that it can be determined according to the principle of cost risk balance (that is, balance between the cost of disaster recovery resources and the possible losses caused by risks).A regular data backup mechanism for important data shall be established, and a complete incremental data backup shall be performed at least once a day, and the backup media shall be stored in a safe area.The key data shall be backed up in real time in the same city and in different places to ensure that business applications can achieve real-time switching.Disaster recovery plan shall be formulated and tested regularly to ensure the correctness of each recovery procedure and the overall effectiveness of the plan.
Hot standby method
Announce
edit
It is another term for server high availability application, which is translated as "high availability". The term "hot standby" is usually based on the free translation, and belongs to the high availability categoryhot standby Only two servers in high availability are limited.Hot standby software is a software solution used to solve an inevitable problem of planned and unplanned system downtime. Of course, it also has hardware.Is to build high availabilityCluster systemOfBasic softwareFor any fault that causes system downtime or service interruption, the software process will be triggered for error determinationFault isolation,, and online recovery to continue the interrupted service.In this process, users only need to experience a certain degree of acceptable delay, and can restore services in the shortest time.
In a narrow sense,hot standby Specifically, it refers to the hot standby (or high availability) of two servers in the high availability system. Because the high availability of two servers is widely used in China, it is called dual hot standby. The dual high availability can be divided into the active standby mode (Active Standby mode) and dual host mode (Active Active mode) according to the switching mode in work,The active standby mode means that one server is in the active state (active state) of a service, and the other server is in the standby state (standby state) of the service.The dual host mode refers to the active standby and standby active state of two different services on two servers.Note: Active Standby status refers to the status of an application or business, not the server status.
There are two main ways to form dual machine hot standby:
The shared storage mode is mainly throughdisk array After providing switchingData integrityAnd continuity.User data is usually placed indisk array When the host goes down, the standby continues to obtain the original data from the disk array.This method is often called disk by industry insiders because it uses a storage deviceSingle point of failure。But generally speaking, the storage security is high.Therefore, if the storage device failure is ignored, this mode is also the most popular hot standby mode in the industry.
2. Data replication based
This mode mainly uses the data synchronization mode to ensure theData consistency。Data synchronizationThere are many methods for data replication, and their performance and security are also different. The main methods are as follows: A. The simple file mode is not suitable for applications such as databases, because open files cannot be copied. If you want to copy, you must close the database, which is obviously not possible.Copying in file mode is mainly applicable to updating WEB pages, uploading applications via FTPData integrity, used when continuity requirements are not high.B、Using the replication function of the database, such as subscription replication of SQLServer2000 or 2005, users should use this method carefully according to their own applications. The main reasons are:
(1) SQL Server subscription replication will add fields to the user tableApplication softwareThe programming requirements are high. If the user does not explicitly specify the field when writing on the application software side, using this function will cause the application to fail to work properly.
(2) The limitation of data retention is probably the most critical, because the data of SQL Server does not arrive at the active and standby machines in real time during data transmission. Instead, the data is written to the host machine first, and then to the standby machine. In this way, the data of the standby machine is often too late to update. If a switch occurs at this time, the data of the standby machine will be incomplete and discontinuous,If the user finds that the written data cannot be found on the standby machine and writes again, after the host is repaired, serious data conflicts between the active and standby machines will occur, and the database will be disordered.
(3) Never use subscription copy for complex applicationshot standby , includingdata structureinstored procedureProcessing,triggerIn case of conflict with the sequence, it is very troublesome to modify it.
(4) The server performance is degraded. For larger databases, the subscription replication of SQL Server 2000 or 2005 will cause the server database to run slowly.In short, subscription replication with SQL Server 2000 or 2005 is mainly used for datasnapshotDon't use him for servicehot standby InData synchronization。 C: Hard disk data interception, which is relatively mature at home and abroadDual computer hot standby softwareIt usually uses the technology of hard disk data interception, usually calledimageThe software is the mirror software. This technology is very mature at present, and the interception methods are also different.a. Partition interception technology, with PluswellHot BackupFor example, he uses a partitionHard disk sectorThe interception technology is to write the data to the hard disk for data extraction through the driver level interception method, and write it to the standby server first to ensure that the data of the standby server is up to date, and then write the data back to the host hard disk.This method will absolutely ensure that the data of the active and standby databases are completely consistent. No matter what kind of switch occurs, the integrity and continuity of the database can be guaranteed.Due to the partition interception technology, users can partition a hard disk into partitions of appropriate size as neededData synchronizationWork.b. The hard disk interception technology, taking Symantec Co Standby as an example, is also an effective hard disk interception software. Its interception is mainly based on a whole hard disk, which often consumes a lot of time when initializing the hard disk.
(5) The latest technology isThird party software，Dual computer hot standby softwareBy capturing the database modification operation and automatically and synchronously taking over the data in real time, you can automatically take over the function on the standby server when the primary server fails. The normal operation of the time system does not require any manual operation business. At present, among the foreign products (IBM, Symantec, Dell, etc.), the domestic products are (Best Backup, Global Shield,PremiumIt takes about 50 seconds for foreign products to take over services, and about 4 seconds for domestic global shields.Automatically take over the work of the main server to ensure 7 * 24 hours non-stop operation.

5. Manual backup of data on the Linux system
Linux system is equipped with powerful tar command, which can flexibly back up data.Tar was originally designed for tape backup, backing up files and directories to tape, and then extracting or restoring files from tape.Of course, now we can use tar to back up data to any storage medium.Tar is very easy to use, stable and reliable, and it is available on any Linux system.Therefore, it is the most frequently used backup tool.Use the tar command to back up data in the following format:
$tar cvf backup.tar/home/html The above command is to set all the files in the/home/html directorycollect files Tar file backup.tar.
Cvf is the command parameter of tar.
C stands for creating an archive file,
V stands for displaying the file name of each backup,
F indicates that the file name created by tar is backup.tar,
/Home/html represents the file or directory name to be backed up by tar.
Use the tar command to recover data in the following format:
Generally, tar does not compress files when backing up files, soBackup filesThe size of is very large.
Use the following command to make tar automatically use the gzip command toBackup filesCompress to get a corresponding gz file$Tar zcvf backup.tar/home/html In this way, we can get two files, backup.tar and backup.tar.gz.Backup.tar.gz is compressedBackup files。

strategy
After selecting storage backup software and storage backup technology (including storage backup hardware and storage backup media), you need to first determine the strategy of data backup.Backup strategy refers to determining the content, time andBackup mode。Each unit should formulate different backup strategies according to its own actual situation.At present, there are three backup strategies that are most used.
Every dayFull backup。For example, on Monday, use one tape to back up the entire system, and on Tuesday, use another tape to back up the entire system, and so on.The advantage of this backup strategy is that in case of a disaster of data loss, only one tape (that is, the backup tape of the day before the disaster) can be used to recover the lost data.However, it also has shortcomings. First, because the entire system isFull backup, resulting in a large number of duplicate backup data.These duplicate data occupy a large amount of tape space, which means increased costs for users.Secondly, due to the large amount of data to be backed up, the time required for backup is also longer.For those companies with busy business and limited backup time, it is unwise to choose this backup strategy.
Once on SundayFull backup, and then only the new or modified data of that day will be backed up in the next six days.The advantage of this backup strategy is that it saves tape space and shortens backup time.However, its disadvantage is that when a disaster occurs, data recovery is more troublesome.For example, if the system failed on Wednesday morning and lost a lot of data, it is necessary to restore the system to the state it was in on Tuesday evening.At this timesystem administratorWe need to find the Sunday dish firstFull backupThe tape is used for system recovery, and then Monday's tape is found to recover Monday's data, and then Tuesday's tape is found to recover Tuesday's data.Obviously, this way is tedious.In addition, the reliability of this backup is also poor.In this caseBackup modeNext, the relationship between the tapes is like a chain, one by one. If any of the tapes goes wrong, the whole chain will be disconnected.For example, in the above example, if the tape on Tuesday comes outfault, the administrator can only restore the system to the state of Monday night at most.
administratorsThe system will be conducted on Sunday firstFull backupThen in the next few days, the administrator will back up all data (new or modified) that is different from Sunday to tape.Differential backupThe strategy avoids the defects of the above two strategies, and at the same time, it has all their advantages.First, it does not need to fully backup the system every day, so the backup time is short and the tape space is saved. Second, itsdisaster recovery It's also very convenient.system administratorYou only need two tapes, the tape on Sunday and the tape on the day before the disaster, to restore the system.
In practical applications, the backup strategy is usually a combination of the above three.For example, once a week from Monday to SaturdayIncremental backuporDifferential backup, every SundayFull backup, a full backup is performed at the end of each month, and a full backup is performed at the end of each year.
4. Problems related to daily maintenance
After the successful installation and commissioning of the backup system, the daily maintenance includes two aspects, namely hardware maintenance andsoftware maintenance。If the hardware equipment has good reliability, the system does not need regular maintenance after normal operation.In general,Tape LibraryThe vulnerable parts ofTape driveWhen a backup read/write error occurs, you should first check the working status of the drive.In case of unexpected power failure, after the system restarts, check whether the connection between equipment and software is normal.The automatic cleaning operation of the head can generally be automatically managed by the backup software. A disk of dlt cleaning tape can be used 20 times, and the head is generally cleaned once a month.software systemThe software and hardware errors and warning messages detected during the work process have obvious prompts and logs, which can be sent to the administrator via email.administratorsThe remote management function can also be used to comprehensively monitor the operation of the backup system.
The establishment of the network data backup system will ensure the safe operation of the system and timely troubleshooting of various system faultsdatabase systemThe timely recovery plays a key role.Through automationTape libraryAnd centralized operation management to ensure the quality of data backup and strengthen the safety management of data backup.At the same time, near lineTape LibraryThe introduction of technology undoubtedly provides a more convenient means for data recovery and utilization.It is hoped that more units can introduce these technologies more quickly, so thatsystem administratorDo not worry about data.
5. Storage data backup and recovery
With the in-depth application of the local area network and the Internet in various units, the server in the system is responsible for the key application of the enterprise, storing important information and data, providing comprehensive information query services for leaders and decision-making departments, and providing fast and efficient information querydata processingAnd internet.Therefore, establish a reliable network data backup system to protect key applicationsdata securityIt is an important task of network construction to ensure that data will not be lost in case of man-made or natural disasters.

Introduction to terms
Hardware level issues: selectingBackup filesStorage device and location used.Software level problems: select backup programs and fully exploit and utilize their functions.
Local backup: in a specific area of the local hard diskBackup files。
Offsite backup: Backup files to storage media separate from the computer, such asfloppy disk、Zip disk, CD, memory card and other media.This is the hardware level problem of backup.
Live backup: Backup to rewritable storage media for updating and modification.
Dead backup: backup to a non erasable storage medium to prevent accidental deletion and intentional tampering.This is also the hardware level problem of backup.
Dynamic backup: use the software function to automatically back up the specified file on a regular basis, or automatically back up at any time after the file content changes.
Static backup: manual backup to keep the original appearance of the file.This is a software level problem with local backup.
4 types
1. Installationsystems softwareFiles formed with application software: computers can operate and realize functions by means of them.These files do not have to be backed up because they can be obtained again by reinstalling the software.However, backup selectivelysystems softwareImportant files (such as WindowsRegistry fileAs well as software, hardware configuration information and user information) and personal configuration in application softwareInformation file(such as personal template) can effectively reduce the trouble of reinstallation.This type of file can only be backed up locally, but it must be backed up statically, because the value of this type of file lies in its originality. Dynamic backup may save the changed or even wrong files as the final backup.
2. Files copied from network and other media (such as downloaded software, literature on media, etc.): some of these files can be recovered, and some will disappear after expiration.For you, it will be unique after downloading, so you must backup it, and it is important toOffsite backup, of course, it is a static backup, because the purpose of copying it is generally to use rather than modify it.
3. Personal information automatically generated by computer or added by users (such as input method vocabulary, web page favorites, etc.);Once such files are lost, they can be re established, but it takes a lot of effort to reorganize them, so they must be backed up.However, they are updated and changed at any time, so it is better to perform local dynamic live backup to restore to the latest state at any time;Of course, it is also necessary to make a non local dead backup at a certain stage.
4. Documents accumulated and edited by oneself (such as address bookE-mail. Various documents edited by ourselves): This is the fruit of our own labor, and it is unique and cannot be recovered. Dynamic backup should be used to record the latest form at any time;After achieving phased results, do staticOffsite backupTo recover in case of error;After the file is completed, at least two dead backups should be made to prevent the backup from being lost, tampered with, or unusable due to damaged storage media.
Of course, these are not dogmatic, clear thinking should also be good at responding.For example, the Windows registry will be modified intentionally or unintentionally at any time during system operation, so it is necessary to perform dynamic backup;But if you do not keep an initial good backup, you may find a registry with fatal errors when you need it most.Therefore, comprehensive application of multiple backup methods is reasonable.
Feasible methods
Select a backup tool: First, good backup hardware can make a good backup solution targeted.Secondly, it is necessary to select a backup program with complete functions so that the software level backup method can be realized.For a normally running system, the backup program works in the background to maintain data synchronization (original files andBackup filesKeep consistent at any time) is an ideal backup scheme.
Select the backup method: After selecting the backup hardware and dynamic backup program, you should also consider the backup method.File or folder backup, whether to filter, how to filter, whether to use compressed backup,Backup filesIs it easy to recover, and do you choose file data synchronization?If you select data synchronization, you should also consider the error factor of the original file. Some illegal operations will cause illegal codes in the original file and prevent it from being opened. If you fully use dynamic backup, the original file and the backup file will be completely synchronized, and the backup file will also be unavailable.Therefore, it is very important to choose a feasible method according to your actual situation.
Select a saving method:Backup filesThis is to recover files in case of accidents. If the backup files are not stored well, all efforts may be wasted.For example, the CIH virus attacks the computer, often devouring all hard disk data. If only the local dynamic backup,Backup filesIt is also within the scope of damage.There are still some man-made damages even more than this.To avoid such situations, it is necessary to adoptOffsite backup。andOffsite backupThe storage medium of may also be tampered with, which requires a dead backup.However, offsite dead backup cannot achieve the purpose of dynamic backup.Therefore, when it is appropriate to do a dynamic backupOffsite backupIt is the most worth promoting security scheme.
Choose a file format: The method of restoring files backed up by different programs and methods is also different.Generally speaking, the backup program based on Windows system produces special formatBackup filesStill want to restore in Windows, especiallyCompressed formatBackup file for.This is not a problem for personal document backupSystem filesThe backup of is not appropriate.yesSystem filesMust be saved as a type that can be directly copied in the DOS environment or can be unpacked in DOSCompressed format, because these backups are always used when the system fails to start.
Usable equipment
Backup is inseparable from storage devices and media.At present, there are many devices that can be used for backup, exceptfloppy disk. In addition to the local hard disk, CD-R, CD-RW discs, Zip disks, active hard disks, removable storage devices, andTape driveIt's very convenient to buy them.In addition, the Internet also provides users withNetwork BackupNew approaches, especially someFree spaceIt is worthy of our attention.
floppy diskIs the most common backup media.however,floppy diskThe capacity is very small. It is barely possible to back up a small amount of data, but it is powerless to back up a large amount of data.Moreover,floppy diskPoor security, easy to damage, professional backup is not worth considering.
CD is a good backup medium. It has large capacity, is easy to keep and carry, and has high security. It can be used for dead backup.
Zip disk has large capacity and is easy to implementOffsite backup。Its cost performance ratio is high.Users with large file exchange volume in different occasions can first consider selecting it as a backup device.
Users who often need mobile jobs can choose medium and large capacity active hard disks as the first choice for backup devices. Although the price is a little expensive, in addition to the backup function, it can also let you take the system and database with you.For those who own digital camerasDigital video cameraAs for the users, the mobile memory card or memory stick can also temporarily backup data.Tape driveIt is an original data carrier, but the performance of the new product has been quite perfect, which is worth choosing for professional users engaged in data production.
If you desalinateOffsite backupThe importance ofBest BackupEquipment.Create a partition on the hard disk that accounts for about 20% of the total capacityBackup filesBackup and restore are very convenient, with the highest efficiency, fastest speed, and highest unit capacity/price ratio.The disadvantage is that this partition cannot be accessed fromcomputer system To be separated from the,Backup filesIt is still under the control of such destructive viruses as CIH.In this regard, you can use document compression backup, establish multi-level directoriesHide FileAnd other methods to mitigate potential hazards.In addition, you can also purchase a small hard disk at a lower price for special backup.
