Set Up Synology C2 Cloud for Seamless Data Backups

How to Set Up Synology C2 Cloud for Seamless Data Backup

Synology C2 Cloud is designed to extend your Synology NAS into a secure, off-site backup destination without adding complex third-party tools or separate portals. When configured correctly, it gives your business an extra layer of protection against ransomware, hardware failure, and site-level disasters, while keeping backup management centralized and efficient.

Below is a practical, business-focused guide to setting up Synology C2 Cloud for seamless data backup, along with how Epis Technology can help you design and maintain a robust backup strategy.

Why Use Synology C2 Cloud for Backup?

Synology C2 integrates tightly with DSM and Synology backup apps, making it ideal for businesses that already rely on Synology NAS. Key advantages include:

• Offsite resilience for disaster recovery and compliance

• Native integration with Hyper Backup and other Synology tools

• End-to-end encryption for sensitive business data

• Centralized management of on-premise and cloud backups

This combination allows you to build a 3-2-1 backup strategy (three copies of data, on two media types, with one offsite) using a consistent Synology ecosystem.

Step 1: Prepare Your Synology NAS and Environment

Before setting up C2 Cloud, make sure your on-premise environment is ready:

• Update DSM to the latest stable version.

• Confirm your NAS has reliable internet connectivity and DNS resolution.

• Verify that time and NTP are correctly configured for accurate logs and scheduling.

• Ensure you have sufficient NAS storage for local backup sets before sending them to C2.

A healthy NAS platform is essential; C2 Cloud should extend your backup strategy, not compensate for an unstable local environment.

Step 2: Create or Sign In to Your Synology Account

Synology C2 Cloud uses your Synology Account for authentication and subscription management.

1. Go to account.synology.com or open the Synology Account link within DSM.

2. Create a new account or sign in with your existing credentials.

3. In the C2 portal, choose the backup service that fits your use case (for example, C2 Backup or C2 Storage, depending on the application you plan to use).

4. Select the data center region that aligns with your latency and regulatory requirements.

Choosing the right region is especially important for businesses that must comply with data residency rules.

Step 3: Connect Synology NAS to C2 Using Hyper Backup

For many environments, Hyper Backup is the primary tool to back up Synology data to C2 Storage.

1. On your Synology NAS, open Package Center and install or update Hyper Backup.

2. Launch Hyper Backup and click Create to start a new backup task.

3. Select Synology C2 Storage as the destination type.

4. Sign in using your Synology Account and choose your C2 storage plan or bucket.

5. Create or select a backup vault to hold your NAS backups in C2.

This connects your NAS to Synology C2 Cloud and prepares a dedicated cloud location for your backup data.

Step 4: Choose Backup Sources, Schedule, and Retention

Next, configure what you want to back up and how often:

• Select shared folders, application data, and system configurations that are business-critical.

• Define a backup schedule that runs outside peak usage hours to reduce performance impact.

• Set retention policies (number of versions, rotation rules, or time-based rules) based on your compliance and recovery needs.

• Enable data integrity checks to ensure backup sets remain healthy over time.

For most organizations, a daily backup schedule with a sensible versioning policy (for example, more frequent recent versions and fewer long-term ones) balances resilience with storage costs.

Step 5: Enable Encryption and Security Controls

Security should be a default, not an afterthought:

• Use client-side encryption where available, creating a strong encryption password or key.

• Store encryption keys securely (for example, in a password manager or secure key management process).

• Turn on 2FA (two-factor authentication) on your Synology Account to protect access to C2.

• Restrict DSM and Synology Account access to authorized admins only.

With encryption and strong authentication in place, your off-site backup data remains protected even if account credentials or physical storage are compromised.

Step 6: Test Backups and Perform Restore Drills

A backup that hasn’t been tested is a risk. After your first successful backup to C2:

• Run a manual backup to confirm the configuration behaves as expected.

• Perform a test restore of a small set of files from C2 back to your NAS or a test location.

• Document the restore procedure, including who is authorized to perform it and under what conditions.

Regular restore drills ensure that, in a real incident, your team can recover quickly and confidently.

How Epis Technology Simplifies Synology C2 Cloud Deployment

Epis Technology helps businesses move from ad-hoc backup practices to a structured, Synology-centric data protection strategy. Instead of leaving IT teams to guess at C2 settings and retention rules, Epis starts by analyzing your workloads, data types, RPO/RTO objectives, and regulatory requirements. Based on this assessment, Epis designs an integrated backup architecture that combines on-premise Synology NAS with Synology C2 Cloud, using Hyper Backup and related tools. The team then configures backup jobs, encryption, retention policies, and monitoring, and performs test restores to validate the design. With Epis Technology managing your Synology environment, you gain a resilient, easy-to-manage backup solution that fits your operational and compliance needs.

Ongoing Monitoring and Optimization

After setup, your backup strategy should evolve with your business:

• Monitor capacity usage in both NAS and C2 to avoid unexpected overages.

• Review backup success rates and alerts regularly.

• Adjust schedules and retention as data volumes or regulations change.

• Keep DSM, Hyper Backup, and other backup-related packages up to date.

By treating Synology C2 as a living part of your IT infrastructure, you maintain a reliable, compliant safety net for your critical data.
