Backup Encryption

Backup encryption protects the contents of saved backup files by making them unreadable without the appropriate decryption credentials. A cleaning company's website backup may contain customer enquiries, account details, or site configuration, so unauthorized access could expose more than public page content. Encryption should be considered both when backups are stored and when they are transferred, according to the system's design. Its effectiveness depends on secure key management, staff access controls, and actual restoration testing. An encrypted backup is not automatically recoverable if the key is lost or the file is damaged. Backup encryption differs from creating backups, choosing retention periods, or scanning for malicious code.
