What is Data Backup? How, where, and when should it be done

Data backup is the process of creating copies of digital information to prevent data loss in the event of data failure, corruption, accidental deletion, or other incidents. It is a fundamental practice to ensure the security and availability of important information.

How to make a Backup?

There are several ways to back up data, and the choice depends on the type of data, the amount of data, and specific needs. Here are some common backup methods:

1. Local Backup:

  • External HDD or flash drive: Connect an external storage device to your computer and manually copy important data.
  • Network Server or NAS (Network Attached Storage): Configure a local network server to store and manage backups.

2. Cloud Backup:

  • Cloud Storage Services: Use services like Google Drive, Dropbox, Microsoft OneDrive, or others to back up data online.
  • Automatic backup: Some services and apps offer automatic backup options to the cloud.

3. Backup Software::

  • Backup Tools: Use dedicated backup software that allows you to schedule, automate, and manage backups. Examples include Acronis True Image, EaseUS Todo Backup, Cobian Backup, and others.

4. Incremental and Differential Backup:

  • Incremental: Make copies of only the data that has changed since the last backup.
  • Differential: Make copies of data that has changed since the last full backup.

Here are some best practices for backing up data:

  • Regularity: Make regular backups to ensure that the most recent data is always protected.
  • Three copies: Keep at least three copies of the data - the original and two backup copies.
  • Keep copies in different locations: Store backup copies in different physical locations for additional protection.
  • Recovery Test: Periodically test data recovery to ensure that your backups are functional. Testing the backup is as important as performing the backup.

To back up, evaluate your specific needs, the volume of data, the sensitivity of the information, and choose a method that suits your case. It's important to be aware that backing up is a proactive practice to prevent data loss, not a reactive solution after loss occurs. Backup means copy. If some information is not present in at least two places, it is the original. And without backup, you will be at risk.

What about cloud backup?

Cloud backup is a popular and effective way to protect important data by storing copies of that data on remote servers accessible over the internet.

Here are some important features and considerations about cloud storage:

Advantages of Cloud Backup

  • Accessibility: Data can be accessed from anywhere with an internet connection.
  • Automation: Many cloud backup services offer automatic options, scheduling backups at regular intervals.
  • Security: Cloud service providers generally implement robust security measures to protect stored data.
  • Scalability: Storage capacity can be easily increased according to the user's needs.
  • Collaboration: Facilitates real-time sharing and collaboration depending on permission settings.

How to backup in the cloud service?

  • Choose a Cloud Service: There are several cloud storage options, such as Google Drive, Dropbox, Microsoft OneDrive, Amazon S3, among others. Choose based on your storage and resource needs.
  • Install the Client: Many services have apps that can be installed on computers and mobile devices to facilitate automatic data upload.
  • Select Data to Backup: Choose the files and folders you want to include in the backup.
  • Backup Settings: Configure backup options such as a regular schedule, backup type (full, incremental, differential), and encryption if necessary.
  • Monitoring: Stay informed about the status of your backups by regularly checking that your data is being updated as expected.

Security and Privacy Considerations

  • Cryptography: Use services that offer end-to-end encryption to protect your data during transmission and while it is stored.
  • Access control: Carefully manage access permissions to data stored in the cloud to ensure privacy.
  • Compliance: Make sure the service you choose complies with the privacy and security regulations that apply to your industry or location.
  • Redundant Backup: Consider backing up to multiple services or locations for additional redundancy.

Cloud backup is a versatile and convenient solution, especially for users who want an affordable, automated approach to data protection. However, it is important to choose a reliable service and implement good security practices to ensure data integrity and privacy.

And when should we do the backup?

The ideal frequency to perform backups depends on the type of data you are dealing with, the importance of that data, and how frequently it changes. Here are some general guidelines for determining when to make backups:

  • Regular Scheduling: Daily, weekly, or monthly - The frequency will depend on the dynamics of your data. If you work with information that is updated daily, a daily backup may be appropriate. If changes are less frequent, weekly or monthly backups may be sufficient.
  • Significant Events: Before Updates or Changes - Make a backup before performing software updates, configuration changes, or any major modifications to the system.
  • Important Transactions: After critical transactions - If you are dealing with transactional data, such as in a business environment, it may be appropriate to make backups after critical transactions.
  • Automatically or in Real Time: Continuous Backup - Some systems and services offer continuous or real-time backup. This ensures that changes to files are immediately replicated to the backup.
  • Before Cleanups or Deletions: Before Deleting Data - If you are about to delete data, make a backup before doing so to avoid accidental loss.
  • Regular Programming: Scheduled Backup - Set up backups at a consistent and convenient time, ensuring that data is always protected.
  • Depending on Sensitivity: Sensitive Data - If data is highly sensitive or critical, consider making more frequent backups to reduce the risk of loss.
  • Recovery Tests: After Critical Activities - After critical events such as data migrations or major upgrades, it is prudent to perform backups and test recovery to ensure the system is functioning as expected.


Remember that the key to a good backup plan is not just frequency, but also consistency, reliability, and regular testing of backup capacity recovery. It's important to adjust your backup strategy as your needs and data environment change. Additionally, consider combining local and cloud backups for a more comprehensive approach.
