Affordable cloud data protection
Unpredictable data center costs, as well as hardware and administration expenses make privately setting up secure remote backup storage a daunting task. C2 Backup plans offer full-featured professional data protection at a predictably low price.
More than what you pay for
Restore full backups, individual files, and multiple historical versions to any destination, with a web portal, desktop client, and Synology NAS integration.
Secure data with military-grade encryption
Enable client-side encryption and make your data unreadable before it leaves your device with advanced AES-256 and RSA-2048 encryption.
A password-protected private key for each task ensures that neither Synology, nor any other person or organization can decrypt, access, or modify your data.
Flexible backup options
Seamlessly integrated with Hyper Backup on your Synology NAS, C2 Backup adds protection and functionality to your existing backup configuration.

Synology C2 Backup plans offer flexibility in features, storage capacity, and costs. Start backing up your Synology NAS with our cost-effective plans.Compare C2 Backup plans and pricing
- * The prices above do not include VAT. Local VAT is added if applicable.
Plan I protects your data through daily backups with a default retention policy. C2 Backup will retain 11 backup versions (one latest, 7 daily, 3 weekly) going back 30 days. Regardless of the cumulative size of your backup versions, only the source data size on your Synology NAS is counted toward your C2 Backup storage usage.
Plan II lets you customize your backup schedules and retention policies. All your backup versions count toward your total C2 Backup storage usage. However, Plan II-exclusive deduplication helps you cut back storage use by reducing duplicate data across different versions.
Extra storage space up to 200TB can be added directly through in-app purchase. To purchase more than 200TB, please contact us.

Privacy & Security
Our servers protect all data from unauthorized breach with encryption-at-rest. Data are rendered unreadable before they are stored to any drive, with decryption keys kept on another system.
Additionally, we strongly recommend that users enable client-side encryption in Hyper Backup. If you enable client-side encryption, your data are rendered unreadable using the advanced AES-256 encryption standard before transmission to Synology C2.
For an additional layer of security, you can enable 2-step verification. Enabling 2-step verification ensures that your data can only be accessed with a code provided by an authenticator app on your mobile phone.
Synology monitors employee access to its storage locations. All data on our servers is protected against breach or physical theft with encryption-at-rest.
Similar to a RAID setup, our erasure coding stripes data into many pieces, with a redundancy of three pieces (meaning three servers can crash and your data will still be available). However, with erasure coding, users do not need to wait for recovery (which is instant). Erasure coding also helps detect and repair corrupted data.
Synology C2 Backup's US colocation data center facilities have achieved comprehensive SOC 2 Type II certification, confirming it has strict procedures in place to keep user data secure.
Synology handles your payment details in compliance with PCI DSS by processing and storing your billing information with a PCI Level 1 Service Provider.
The Health Insurance Portability and Accountability Act (HIPAA) of 1996 introduced regulatory standards for the lawful use and disclosure of protected health information (PHI). The legislation demands that any company working with PHI comply with the Security Rule and the Privacy Rule set by HHS.
Synology C2 allows users to comply with HIPAA standards. Synology C2 services are built under the supervision of our Product Security Incident Response Team (PSIRT) engineers.
All PHI transferred to and stored on Synology C2 is protected by encryption-at-rest. In addition, Synology C2 users can enable client-side encryption to make PHI data unreadable using advanced AES-256 and RSA-2048 encryption before they upload such data to Synology C2.
It is each user's responsibility to enable client-side encryption before uploading PHI to Synology C2.
For more information on our data protection technologies, refer to our C2 Backup Data Encryption and Durability Strategy.
Synology will never access data stored to Synology C2, including PHI, unless required by the user or by law. Users maintain full control over PHI on Synology C2. Only users can amend, use, and maintain their own PHI data on Synology C2.
