Backups: incremental, full or differential
When planning company IT, we should never neglect the issue of security. One of the most basic aspects of IT security is data protection. Losing company data is not only a practical inconvenience, it can also cause us to lose profits and customers. To protect ourselves, we need to make regular backups.

When planning company IT, we should never neglect the issue of security. One of the most basic aspects of IT security is data protection. Losing company data is not only a practical inconvenience, it can also cause us to lose profits and customers. To protect ourselves, we need to make regular backups. In this article we explain how to protect our data. the basic types of backups: incremental, full, and differential.
The full backup
This type of backup is the most basicAs its name suggests, it consists of copying all the data onto a single medium: hard drive, DVD or CD, cloud server... Its great advantage is that all the data is stored in a single place, which allows for reduced data recovery time. Its disadvantages are that it takes longer than other types of backup and, logically, it also requires more storage space. For all these reasons, we do not recommend a full backup every time we want to incorporate new data, but only periodically, as a security measure. The normal thing is to combine this type of backup with the other two types: incremental and differential.Incremental backup
An incremental backup is a partial backup, which only collects the latest data since the last backup was made. To do this, the system analyzes the data about the modification time and date that are part of the files. If that time and date are later than the last backup, they are saved in the new backup. This type of backup can be done as often as we consider convenient, since it only saves the latest data. Compared to full backups, incremental backup takes up much less space and is saved much faster.Differential backup
This type of backup can be seen as an intermediate option, as it saves more information than an incremental backup but less than a full backup. Simply put, a differential backup saves all the data that has changed since the last full backup. This means that the first time you do a differential backup after a full backup, it will save the same information as an incremental backup, as it will copy all the data that has changed since the last backup. However, when you continue doing differential backups, they will still record all the changes since the full backup and not since the last backup. Differential backups take longer than an incremental backup but less than a full backup, and the same goes for the amount of storage space they require. In general, to have a good backup system, you should combine these options. A very common strategy is to do a full backup once a week and complement it with a daily incremental or differential backup. Finally, remember: the goal is not to make backups per se, but to be able to recover the data. That's why it's essential to check your backups periodically to make sure everything is in order. Now you know the types of backup that exist, but do you know how to recover deleted data? Read our post 'How to Recover Deleted Data from a Cloud Backup' to find out. It can be of great help to you!
