I believe you who are reading this article have your own website. Is the website important to you? Is the data important to you? The answer is yes. If it’s not important, why are we building a website? So how much do you know about how to back up website data?
Backup is no longer a cumbersome task. The continuous research and introduction of software and hardware products have made data backup features such as fast speed, high reliability, and strong automation, completely relieving the burden of system administrators. In terms of investment, compared with building a network, dedicated storage devices and backup software are very cheap and will not become a financial burden for users at all. If every server or every local area network is equipped with a data backup device and properly utilized, it can be easily restored regardless of network hardware or software problems.
I believe everyone is afraid of something like this happening: accidentally typing the wrong key, and the results of several hours or even days of work will be wasted. According to statistics, more than 80% of data loss is caused by people's incorrect operations. Unfortunately, such erroneous operations can never be avoided by humans. On the other hand, with the widespread establishment of the Internet, people are transmitting a large amount of information through the Internet. In the network environment, in addition to human errors, there are also various virus infections, system failures, line failures, etc., which make the security of data and information unable to be guaranteed, and our large investment in the network is meaningless. . In this case, if you have timely backup in advance, there is nothing to worry about. But how many people are so ‘witty’?
Maybe you haven’t had a large number of catastrophic data loss incidents yet, but that doesn’t mean disaster will never hit your network system. The imperfect network environment and various prevention facilities in our country also make it extremely easy for viruses to breed and spread, posing a great threat to data security. Therefore, before we taste the bitter consequences of disaster, let us act as soon as possible to make reliable backups of our precious data.
Principles of data backup: Backing up data is to ensure data security and eliminate worries for system users and operators. Different application environments require different solutions to adapt. Generally speaking, the following principles must be met:
Stability The main function of a backup product is to provide a data protection method for the system, so the stability of the product itself becomes the most important aspect. It must be 100% compatible with the operating system.
Comprehensiveness In a complex computer network environment, it may include various operating platforms, such as Windows, UNIX, etc., and install various application systems, such as databases, groupware systems, etc. The backup software selected must support various operating systems, databases, and typical applications. For example, multiple backups support multiple systems: various Linux (CentOS, Redhat Enterprise, Ubuntu, SUSE, etc.), Unix (AIX system, etc.), Windows (regular version, ultimate version, data center version, etc.)
Automation: Due to the nature of their work, many units have certain restrictions on when to back up and how long it takes to back up. The system load is light during off-hours and is suitable for backup. However, this will increase the burden on the system administrator, and may also bring potential risks to backup security due to mental state and other reasons. Therefore, the backup solution should be able to provide scheduled automatic backup and use technologies such as tape libraries to automatically change tapes. During the automatic backup process, there is also a logging function and automatic alarm when abnormal conditions occur. The multi-backup SaaS application is very user-friendly in this regard. The backup frequency and bandwidth selection are free, and it is also accurate enough to back up once an hour.
High performance With the continuous development of business, more and more data are being updated faster and faster. It is too late to back up so much content during breaks, and backing up during working hours will affect system performance. This requires that when designing backup, try to consider increasing the speed of data backup and use multiple tape drives to operate in parallel.
Security Computer networks are high-speed channels for the spread of computer viruses, which pose a great threat to data security. If you back up all computer viruses during backup, it will be a vicious cycle. Therefore, it is required to have virus checking, anti-virus, and anti-virus functions during the backup process to ensure virus-free backup. Multi-backup security has reached a certain level. Multi-threads are transmitted in parallel to multiple backup servers and compressed and AES encrypted. A 3-layer security system ensures data security.
Simple operation Data backup is used in different fields, and the operators who perform data backup are also at different levels. This requires an intuitive and simple-to-operate graphical user interface to shorten the operator's learning time and reduce the operator's work pressure, so that the backup work can be easily set up and completed. Simple operation with multiple backups, easily protect your data in 55 seconds.
Real-time performance: Some critical tasks need to run 24 hours a day without any downtime. During backup, some files may still be open. Then when performing backup, measures should be taken to check the file size in real time and conduct transaction tracking to ensure that all files in the system are correctly backed up.
Fault tolerance Data is backed up on tapes. It is also a crucial aspect to protect the tapes and confirm the reliability of the data in the backup tapes. If RAID technology is introduced and the tapes are mirrored, data security and reliability can be better ensured, and an additional safety lock can be added to the user.
Choose multiple backups, your data protection expert!
