Data Backup

Backup: how to protect your data

It’s not today that you hear about protecting your data on your computer. The loss of information occurs for several reasons: power outages that damage equipment, hacker invasion or even numerous types of viruses. And in the blink of an eye, you can lose important information simply because you don’t back up your data.

You may not know the scale of the problem that data loss can cause, but in some cases, you can consider this a problem of gigantic proportions.

In a clinical analysis laboratory, for example, you keep very valuable information about the patients you see there. All the history of consultations, exams, procedures performed, are information that must be kept safe, because it is the patient’s life. Losing this data would be as if that patient had never performed any procedure in his laboratory or clinic. Imagine the proportion that this can take. You don’t want to face problems and at least not see the image of your laboratory or clinic being exposed in a negative way, isn’t that true?

That’s why it’s essential that you back up your data on a daily basis and store it on external media or in a cloud, so you’ll ensure the security of the information and the credibility of your company.

In today’s post, we explain what backup is, how it can be performed and the importance of making this investment through safe and recognized tools.

What is backup?

Backup is a backup of data from one storage device to another. Its main purpose is to restore the information in case of loss of the original data. Backup is a fundamental practice to protect your data from accidental deletion, file corruption or cyber crime, for example.

It should preferably be performed on external storage drives. Thus, if a problem occurs at the data source, backups are not affected. Imagine that you suffer an attack from a hacker involving data encryption. He asks for a ransom to release the information. If your backup is in the same environment as the data, the intrusion compromises your company’s backup. In other words, it becomes useless.

A very important point about backup is its automation. Protecting your data is a constant necessity. In a clinical analysis laboratory, for example, thousands of new data are created daily. If the backup does not occur constantly, you are at risk. That’s because there’s no time for incidents to occur.

Faced with this fact, there are two tips fundamental to make your backup:

  • Have several backups of the files, because failures or inconsistencies can be replicated in the backups;
  • Automate your backup: it’s a way of not forgetting to make the backup and make better use of the workday, since it can be scheduled at alternative times, after hours.

Types of backup

According to the procedure done, the backups can be classified in

  • Incremental backup: copy of data that has changed since the last backup made.
  • Differential backup: similar to incremental backup, but instead of creating a copy of the data that has changed since the last backup, it creates a copy of all the data that has changed since the last full backup.
  • Full backup: creates a full copy of the data.

Besides this classification, there is a difference between the backups, considering the storage location of the backups. There are two main ones:

  • Backup on media or physical server: storage on external hard drives (HDs), DVDs, CDs, pen drives, servers.
  • Cloud backup: storage is done on a virtual remote server, which can be accessed over the Internet. It is, in other words, using the storage space of another computer. There are free services like Dropbox, Google Drive, One Drive, iCloud etc., but there are paid and robust solutions for companies with large volumes of data.

Cloud backup is the most used today to protect your data, because storing on strategic business physical data servers can put your organization’s intelligence at risk. In your clinical analysis lab, all it takes is one glass of water falling on the CPU or the hard drive falling off the table to raise a problem. Your data can be lost by silly incidents.

Backing up in the cloud avoids this type of incident. Information is stored on virtual and decentralized servers, which helps protect your data.

Backup procedures

Backup procedures vary depending on the type of storage.

If you choose to backup to physical media, for example, you can do it manually to protect your data. It’s the same as putting a file on a flash drive. In Windows, you can also protect your data by using the “Easy Transfer from Windows” feature to take it to a different computer. In older versions, there is the “Backup and Restore Center” (Windows 7 and Windows Vista) and the “File Transfer and Settings Wizard” (Windows Server 2003/2000 and XP).

There are also the backup software for Windows and MacOS besides the native operating system wizards. Besides helping in practice, these programs offer automation, encryption, scheduling, synchronization with the cloud and with other devices. Among them are AOMEI Backupper, Acronis Backup, Backup Maker and others. In any case, follow the instructions of the tutorial links.

The main tip is not to back up a computer on the same hard drive where your operating system is installed. Another important tip is to store the physical media in a safe place to avoid access by unauthorized people and, if you find it necessary, use encryption.
