Encryption: Password-Protected Archives

Secure your backups with Cloudback's AES-256 encryption and password protection, ensuring data confidentiality and tamper-proof archives.

Every backup is stored as a ZIP archive that is automatically encrypted with a unique, system-generated password. This ensures that your backup data remains confidential and tamper-proof.

Encryption Standards

The archive is built using ZIP File Version 5.2arrow-up-right combined with AES-256arrow-up-right encryption—one of the strongest encryption methods available.

Note: Many built-in ZIP utilities (e.g., Microsoft Windows Compressed Folders) do not support AES encryption. For optimal compatibility, we recommend third-party tools such as 7-Ziparrow-up-right.

Double-Archive Method

To protect filenames, Cloudback embeds one ZIP archive inside another. Filename encryption is introduced in ZIP File Format Specification 6.2arrow-up-right. We use version 5.2 for better compatibility while still protecting your filenames.

Managing Encryption Settings

For customer managed storages, you have the option to disable archive encryption:

  • Disabling Encryption: Edit your customer managed storage settings and select ZIP archive without password protection.

    WARNING: Disabling encryption requires that you implement alternative measures to secure your data.

  • Enabling Encryption: To ensure maximum security, choose Password-protected ZIP archive.

Setting up archive type

Cloudback-managed storages always enforce password protection to maximize data safety.
