3.1. Backup copying

Backup is one of the key measures to ensure data security. It allows you to protect important data from loss caused by a variety of reasons, such as:

  1. Technical errors. Hard disk failures, software errors or other technical problems can cause data loss.
  2. Human error. Data deletion or corruption due to carelessness (e.g. incorrect operations) is a common problem.
  3. Malware. Viruses and other malware can damage or insert code that destroys data.
  4. Natural disasters. Fires, floods or other natural disasters can cause physical damage to servers or computers containing important data.
  5. Theft. Data can be stolen along with devices.

To ensure effective backup, it is important to:

  • Regular backups.
  • Keep copies in different locations (e.g. in the cloud, on storage media).
  • Check backup recovery processes to make sure they are working as intended.
  • Use automatic backups to reduce the chance of errors.

Another important aspect is that in addition to backups, other data security measures such as encryption, network security, firewalls, anti-virus, etc. should be applied.
