The following situation may sound all too familiar for a lot of computer users: a valuable file has been accidentally deleted and there’s no backup copy. The file is now gone forever – how irritating. If a lot of data is concerned, it can be devastating, especially for businesses. Therefore it’s indispensable to back up business data as well as private data.
As integral elements of any business software, database systems play a big role when it comes to web hosting. This is due to the functionality of the website (and the capability of the business) relying heavily on the stored data being available.
Database-accessing website projects use different scripting languages to gather all the necessary information in order to then correctly display the page. The IT infrastructure of a business usually draws its information from underlying databases. The data exchange also takes place in the reverse direction since users save data in the database. This means it’s not uncommon for these systems to contain personal and financial information or sensitive customer data. Therefore a database error, or even a loss of data, can have serious consequences. It could be that the website doesn’t display the content properly or is completely offline, apps don’t function anymore, and customer data is incomplete or, as is often the problem in the worst case scenario, non-existent. Not only does retrieving this data prove to be a significant hassle, it also agitates customers, which could lead to a loss of trust.
The cause for data loss is usually not an outsider attack, but rather a technical hardware failure or simply user error. Even the best security software won’t be of much help. Therefore a data backup is recommended so that data loss isn’t irreversible.
In order to prevent data loss, you should create backup copies of the database on an external storage device. Having these copies allows you to recover the database beginning from the moment of the initial data backup. There are differences between online and offline backups: online backups are created without having to shut down the database. During the security process, the database records the undertaken changes in a separate area and adds them to the relevant file at the end of the process. If you shut it down during the backup, this is an offline backup. This data backup technique has the advantage of being relatively easy to perform, but it also means that the applications or websites won’t be available during the course of the backup process. If possible, it makes more sense to perform an offline backup during the night when there is less data traffic.
Regarding the breakdown of online and offline backups: they can be split into the following three types depending on the way the data is transferred:
As you can see there are a few options for backing up database systems such as SQL databases or Microsoft Access. The most suitable backup method depends on the needs of the user or business. Skipping backups in order to save storage memory should never be done. External storage devices like hard drives should be kept in a separate area where they are protected from theft and fire damage. The saved data should additionally be encrypted so that if it’s stolen, it can’t be used by any third parties.
You’ve decided on a backup solution and now the next step is to decide how to implement it. There are different possibilities and tools to back up databases like a SQL database. The following list explains some of the options:
The saved files in databases often play a big part in the smooth execution of a business and the correct layout of websites. Web servers access the information in order to present the hosted website correctly. The functionality of the applications in the network is often directly linked to a database. Databases also create the storage location of sensitive data such as addresses, account numbers, and telephone numbers.
Since they play such an important role, database systems should definitely be protected by adequate security measures. Your data isn’t just threatened from outsider attacks, but also from internal problems such as hardware failure or user error. Regular backups prevent data loss and guarantee long-term data security.
Operating and managing a remote server located in a data center is often carried out by using a secure network connection provided by the SSH protocol. The necessary registration on the server is preceded by an authentication process. Usually this occurs in the form of the username and password. Alternative methods such as the public key authentication used by SSH, do have their advantages. But...
It only takes a few seconds for a hacker to gain access to your private data without you having any idea. More often than not, a password is the only means of protection when logging into online services; and if it is too obvious, it will not prove too much of a challenge for criminals to crack. There are numerous options to increase password security.
For server operators, security is of the utmost importance. Only those who have developed and set up a foolproof defense strategy are ready for drastic situations. As well as regular protection mechanisms, like security software, backups, and encryption, there are also some useful tools and frameworks that may come in handy in the fight against intruders. We have laid out essential details on the...
