Essential for the protection of personal and corporate data, backup is a preventive measure that avoids unexpected events and reduces the risk of loss in the event of missing information and documents.

To inform and make our readers aware of the need for backup, we, the Codeblog team, have prepared a comprehensive article presenting the definition, importance, and most common types, as well as relevant tips to ensure the effectiveness of the process. Read on and check it out!

What is a backup?

In practice, a backup is a security copy of digital data aimed at keeping files safe and protected, even in the event of incidents such as accidental deletions, thefts, or loss of data and information.
By keeping the backup updated, it is possible to quickly restore lost files and documents, thereby avoiding major problems for the company.
Due to its importance, especially in a business context, it is currently possible for backups to be performed in several different ways. The process can be implemented in on-premises physical installations or in the cloud according to the institution's preference.
Additionally, in some cases, there is the possibility of automating it to allow it to be triggered remotely, emitting metrics and reports after it is completed.

Why is backup important?

As mentioned earlier, backup helps protect data and contributes to the continuity of business processes. After all, with the rapid recovery of data, the team does not remain idle.
No matter how numerous the causes that lead to the loss and misplacement of information are, undoubtedly, having a backup copy ensures they are restored more easily and quickly.
Natural disasters, virtual attacks, cybercrimes, and even hardware failures are unpredictable events; therefore, it is extremely important for an organization to be secure and prepared to act effectively if any failure causes data loss.

Types of backup

To ensure data security, there are three types of backup that define how and what information is copied. Learn more about them in the following topics:

Full (or complete backup)

A Full Backup copies all files stored on a device, system, or database. Due to the volume of data, this is the backup that takes the longest to complete and occupies more space on the disk or in the cloud. However, it ensures greater security and quick restoration.

Differential Backup

A Differential Backup saves only the copies of files that have changed since the last full backup. Practical and secure, it uses less disk or cloud space compared to a full backup.

Incremental Backup

An Incremental Backup saves security copies of files that have changed since the completion of the most recent backup. It is considered the fastest process compared to the others and requires less storage space. On the other hand, it is not considered as secure as Full and Differential backups, as it depends on all recent copies, making it more susceptible to data loss.

Tips to ensure the efficiency of your backup

Define what is a priority: Although all information needs protection, it is important to define which are priorities, such as access passwords, financial data, and sensitive customer data, among others.

Analyze the backup types and define which one best suits your needs

Is it worth implementing a full backup daily? How often do incidents occur with your company's information? Has your business already suffered an attempt or had information stolen by crackers? These and other questions must be considered when analyzing which type of backup is most suitable for your organization.

Define the frequency

Returning to the priority issue, it is important to select which data is constantly modified and then prioritize it in the backup schedule to aim for the reduction of the RPO (Recovery Point Objectives), defining the maximum allowed volume of data lost in a failure occurrence since the last backup, and then limiting the rollback time period.

Think about scalability

Scalability is essential for the effectiveness of internal processes and, consequently, for business maintenance. Therefore, periodically review the scope of the backup and analyze the potential growth of data volume. Monitor the environment regularly and look for the presence or alteration of systems that may require increased protection or even an increase in volume.

Bet on cloud backup

With state-of-the-art technology, cloud service providers, besides offering uncomplicated backup, also recover data at any time in just a few clicks, ensuring flexibility and protection in managing backup copies.
Additionally, in cloud backup, storage is done through virtual cloud computing servers that do not require physical installations and do not cause interruptions to processes. Another advantage is that, by choosing cloud technology to store your files, you have the option of expanding the contracted volume according to your needs.
The cloud is also supported by various privacy configurations, which integrate confidential archives and protect all sensitive user data. Therefore, investing in cloud computing is a secure way to store data and make it available in a personalized way, avoiding the loss or misplacement of important files and documents.
