Backup Encryption - Everything You Need to Know

Larissa updated on Feb 22, 2023 to Knowledge Center

Having multiple redundant backups of your data is a critical part of having an effective security and backup strategy, but knowing how to encrypt your backups is just as important. 

Today, almost all data is exposed to the monitoring of network big data, which also gives some criminals the opportunity to steal and destroy important data. Even though you have backed up your important files and data, it doesn't mean they are completely safe. Because these cybercriminals also target backups to leak or sell information.

Backup encryption adds another layer of protection to your sensitive information, ensuring that should your media ever fall into the wrong hands, it will remain secure.

What Does Backup Encryption Mean

Backup encryption has become the choice for most businesses and enterprises, but do you know what backup encryption really means?

Backup encryption means adding a certain password or code to make the information invisible to anyone else except those who know the password. It is an important security measure for any data that needs to be kept secure, which adds a layer of encryption on backup files, such as personal backup files and business backup data, to ensure that unauthorized persons cannot gain access to the data. It ensures unauthorized individuals can’t access or manipulate the data, resulting in a much higher level of protection than simply relying on password protection. 

There are two common types of backup encryption. The first one is called sysmmetric encryption, which uses the same encryption keys to encrypt plaintext and decrypt ciphertext. The second one is called asymmetric encryption which using a pair of related keys(one public and the other private) to encrypt and decrypt backup files. 

The Benefits of Encrypted Backup

Backup encryption can protect against malicious attackers and help prevent data breaches. Here are some of the main benefits of encrypted backup

  • Increased Security - Encrypted backup provides an additional layer of security to your backup files. Encrypting backup files ensures the information is kept secure from malicious attackers, as only those with access to the encryption password or code can view or manipulate the data. 
  • Compliance - For businesses in regulated industries, backup encryption may be a requirement for compliance with various laws and regulations. 
  • Easier Recovery - If you ever need to recover backup files, backup encryption can make the process much easier. Because backup files are encrypted with a unique password, backup files are secure and easy to access for those who know the password. 
  • Improved Reliability - Encrypted backup can also help maintain data integrity. With the backups encrypted, the backup files can’t be tampered with or corrupted by unauthorized personnel.
  • Authentication - The encrypted backups are only accessible and visible to those who get the correct authentication code and method, which can prevent important information from falling into the wrong hands.
