C2 Disaster Recovery

Cloud-based disaster recovery plan specifically designed for your Synology NAS

File service uptime maximization

Unexpected service disruptions can cost your company big money as well as cause logistical headaches for your IT department. With Synology C2 Disaster Recovery and its flexible cost plan, file service uptime can be maximized by replicating local DSM servers to Synology C2. In the event that your Synology NAS goes offline due to an accident, you can switch services over to the virtually created DSM on Synology C2 smoothly.

File service continuity

Cloud protection ensures the continuity of common file services, including, File Station, FTP, SMB, and AFP.

1-hour RPO

The hourly data replication allows businesses to resume file services on the C2 server using files in a state within the past one hour before the disaster occurs.

15-minute RTO

When a disaster strikes your local NAS server, the C2 server can swiftly become online to take over file services within 15 minutes.

Flexible investment

Building your own data center for recovery purposes can be costly and the flexibility for future expansion is quite limited. With Synology C2 Disaster Recovery, only the required storage is allocated on the C2 cloud initially and you can expand the storage as your business grows, allowing you to make the investment wisely.

Simple yet powerful cloud protection

With all the complicated steps simplified, Synology C2 Disaster Recovery provides a flexible and easy way to manage the disaster recovery solution for your critical file services.

Start small

No need to invest large for the fixed hardware cost, you can start small with Synology C2 Disaster Recovery for your current need and flexibly add storage as your business grows.

Flexible replication schedule

Depends on business needs, IT administrators can adjust how frequent data is replicated from local Synology NAS to C2 server, from every day to as short as every hour.

Effortless failover process

Minimize the failover process is critical to reducing service unavailability. With Synology C2 Disaster Recovery, the entire failover process can be done easily and intuitively on the C2 console, allowing business to resume file services with the minimal time.

Secure access

With the deployment of VPN, files can be seamlessly accessible via SMB/AFP with same level of security and reliability even with the failed-over to C2 server.

Assured recovery with regular test failover plan

IT administrators can be well prepared for unexpected events by running test failover operations from time to time, shortening the time required for switching over when an unexpected event occurs.

Hassle-free management

Managing service recovery can be a hassle, especially when unexpected event strikes. Synology C2 Disaster Recovery simplifies the entire setup process. With the intuitive user interface and web-based overview tool, you may easily monitor the overall status and perform essential operations whenever necessary. Learn more about setup

System requirements

  • DSM 6.1.3 must be installed and updated to the latest version.
  • All volumes must be running the Btrfs file system.
  • DSM ports must be set as default (5000 for HTTP and 5001 for HTTPS).
  • The maximum number of shared folders cannot exceed 64.
  • The maximum number of volumes cannot exceed 1.
  • The total size used by all volumes cannot exceed 8 TB.
  • Synology’s Disaster Recovery must be installed.
    1. Enable “Beta channel” in the settings page of Package Center.
    2. Install Disaster Recovery from Package Center.
    3. Launch the package and follow the wizard to complete the setup.

During the beta stage, the following packages need to be stopped or removed before you continue with Synology C2 Disaster Recovery:

  • iSCSI LUN/Target
  • Surveillance Station
  • Synology High Availability
  • Snapshot Replication
  • Virtual Machine Manager
What will happen to my data when the Synology C2 Disaster Recovery beta program ends?
You will be notified of the end date of the beta program via email. If you wish to keep all your data and continue using Synology C2 Disaster Recovery, you can subscribe to our plans, which will become available before the official launch of Synology C2 Disaster Recovery. Please note that all beta testers’ data will be deleted after the beta program ends.

Storage

How much space will be allocated on Synology C2 for my NAS?

The space allocated on Synology C2 is based on the number and usage size of volumes on your local NAS, in terabytes. For example, if you have a 1.3-TB volume and a 0.5-TB volume in total on your local NAS, then a 2-TB volume and a 1-TB volume will be allocated on Synology C2, respectively.

If the current size of your volume is close to the next terabyte, Synology C2 will automatically allocate one extra terabyte. For example, 3 TB will be allocate on Synology C2 for an existing volume of 1.9 TB on your NAS.

What data will be replicated to Synology C2?
To ensure that the required services and system files are properly replicated for service continuity, all data on your Synology NAS will be replicated to the C2 cloud. In order to allocate the storage required on Synology C2 efficiently, it is highly recommended that you dedicate the Synology NAS solely to important data storage.
Can I expand storage on Synology C2?
Sufficient storage on Synology C2 is automatically allocated when you create a protection task from Synology’s Disaster Recovery package. The expansion of storage on Synology C2 will be supported when the service is officially launched. During the beta period, you can reduce the data size on the local NAS to manage size usage.

Service

How long does the initial replication take?
The replication speed is determined by Internet bandwidth, network traffic, the data size of your Synology NAS and other factors. Therefore, a specific speed for the initial replication to Synology C2 Disaster Recovery cannot be guaranteed. In general, with a 20 Mbps upload speed, it may take about 3 days to transfer 500 GB data.
Is VPN required for running Disaster Recovery?

Synology C2 Disaster Recovery supports accessing files via File Station, FTP, SMB, and AFP. Among these services, File Station and FTP are designed to run on the Internet and do not require VPN connection. However, as SMB and AFP are the two most common file protocols used within the local area network for security purposes, it is necessary to set up a VPN server for Synology C2 to connect to a local area network if you want to access files via SMB or AFP.
