Data backup

The term "backup" is used to describe the backup of files. This is data that helps to recreate information in case of loss. Backup is often forgotten by company managers, although it is the basis of IT system security. What is the danger of losing data, how much does a backup cost, what are the types of backups, what are the benefits for the company and what is the difference between a backup and an archive - you will learn all this from this article.

Risk of data loss

A good data backup protects the company in case of loss or damage. Incorrect configuration of the IT system, factory equipment defects, years of operation, low quality of maintenance - all these factors can affect the unreliability of the IT infrastructure. Data can also be lost as a result of accidents, theft or accidents at random.

How much does it cost?

It is difficult to determine the specific cost of such a service. It all depends on the size of the company, its needs, as well as the type of backup chosen. There are many companies on the market offering data backup services, so it is worth comparing current offers. It should be taken into account that the cost of the backup is several times lower than the price of data recovery in case of data loss.

Backup types

  • Full - all data is copied to one medium. On the one hand, such backup requires a lot of time, and on the other hand, recovering data from the media is not very time-consuming.
  • Growing - the fastest backup method, but requires the most time to recover files. It involves copying files that are new and those that were modified after the last backup.
  • Differential - in this case only those data that were changed after the last full backup are copied. Both the amount of data and the backup time are increasing from week to week.

Benefits for the company

By far the biggest advantage of backups is the protection of data against loss, which gives a sense of security. In the event of a failure, data is recovered very quickly, without extending the interruption in the daily operation of the company. This ensures that business continuity is maintained. Backup also allows you to protect your company against financial losses, and the cost of the service itself is low compared to your own dedicated backup office.

Backup and archiving

Security and data archiving are very often confused with the concept of backup. Meanwhile, archiving consists of dividing data into active, inactive and reference data. Archived data is usually available to users in the form of references, while in the case of a backup, it is copied to another location.
