Data backup is crucial to safeguarding valuable information and ensuring business continuity. Synology C2 Backup is a cloud-based backup solution that offers comprehensive data protection for devices and Microsoft 365 services. It provides users with a secure and convenient way to back up and restore their data while maintaining the highest level of data security.
Key Security Principles
C2 Backup follows a privacy-by-design approach, minimizing the sensitive user data it possesses. By not storing the C2 Key on the Synology C2 server, users maintain complete ownership and control over their data. End-to-end encryption and client-side encryption further enhance data protection, making it nearly impossible for unauthorized access.
Synology C2 Backup Scenarios
Device Backup: C2 Backup allows users to back up their entire device, including files, applications, and system configurations. By setting up a single backup task, users can automate regular backups, ensuring data safety and minimizing the risk of data loss in case of hardware failure or accidental deletion.
Microsoft 365 Backup: C2 Backup extends its capabilities to include backing up and restoring Microsoft 365 items. This feature is useful for businesses relying on Microsoft 365 services for their day-to-day operations. With C2 Backup, users can protect critical data such as emails, calendars, contacts, and OneDrive files, safeguarding against accidental deletions, ransomware attacks, or service outages.
Data Security and Privacy: Synology C2 Backup prioritizes data security by employing military-grade encryption technology. By encrypting data on the client side, during backup, storage, and restoration, C2 Backup ensures that sensitive information remains safe and protected. With the C2 Key owned solely by the user, data privacy is maintained at all times.
Transparent Service Usage: Synology values transparency and trust for service usage data collection. Users are always asked for permission before any data is collected. The company’s dedicated team promptly addresses any reported bugs or vulnerabilities, ensuring high-level service quality and security.
C2 Backup Encryption Methods
Synology C2 Backup employs two encryption technologies to ensure data security:
AES Encryption: Advanced Encryption Standard (AES) is a symmetric encryption method that uses the same key for encryption and decryption. This encryption method ensures a secure connection between the sender and the recipient, requiring both parties to possess the same key.
RSA Encryption: Rivest–Shamir–Adleman (RSA) is an asymmetric encryption method that uses a key pair of public key and private key. Data encrypted with the public key can only be decrypted with the corresponding private key, enhancing data safety.
C2 Backup User Data Protection
To protect user data, C2 Backup encrypts backup data stored on the C2 server. The encryption key, known as the C2 Key, is provided by the user and is used to derive the AES-256-CBC encryption. This process reduces the vulnerability to brute-force attacks.
Registration and Verification of C2 Encryption Key
During the initial setup, users register their C2 Key, ensuring access to their data. The registration process involves encrypting verification codes, generating key pairs, and encrypting the keys on the client side. The C2 Key server remains unaware of the encryption key, further enhancing data security.
Changing Encryption Keys and Recovery
C2 Backup allows users to change their encryption keys to maintain data security. Users can create a new C2 Key and re-encrypt previously stored data. The recovery process allows users to regain access to their encrypted data if they forget their C2 Key. The Recovery Code, generated during the setup, is essential.
Conclusion
Synology C2 Backup offers a reliable and secure cloud-based backup solution for users looking to protect their valuable data. With its robust encryption methods, including AES and RSA encryption, C2 Backup ensures data privacy and security at every stage of the backup and restoration process. Whether it’s backing up devices or safeguarding Microsoft 365 services, C2 Backup provides users with peace of mind and the ability to recover their data in the event of hardware failure, accidental deletion, or cyberattacks. With a strong emphasis on user control and privacy, Synology C2 Backup is a trusted solution for individuals and businesses seeking comprehensive data protection.
