How to Backup & Sync Synology NAS to Wasabi: 4 Methods

In this article, we’ll discuss how to backup and sync files from your Synology NAS to Wasabi cloud storage with one of the following four methods:

  1. Performing a manual backup (i.e., downloading and uploading files): This method is best if you’re only backing up a few files and have the time and manpower to upload and download them by hand.

  2. Using Synology Hyper Backup (to backup files to Wasabi): This method is best for periodic backup jobs in simple, homogeneous environments where real-time replication isn’t needed — i.e., backing up files from just a few endpoints, while utilizing stable network connections.

  3. Using Synology Cloud Sync (to sync files to Wasabi): This method is best for periodic sync jobs in simple, homogeneous environments.

  4. Using Resilio: Resilio offers an extremely efficient and reliable solution to back up and sync Synology NAS systems with Wasabi cloud storage.  A Resilio agent runs directly on each Synology NAS. It can be used to transfer and synchronize files bidirectionally (or in any direction) to Wasabi cloud storage in real-time or on-demand.

How to Manually Backup Synology to Wasabi

If you only need to perform a simple backup of a small number of files and/or don’t want to invest in 3rd party tools, then you can backup files from Synology to Wasabi by downloading and uploading the files manually.

Step 1: Log into your Synology NAS.

Step 2: Download the files you want to back up.

Step 3: Log into your Wasabi account and select the bucket where you want to store the files.

Step 4: Upload the files to Wasabi by either:

  • Dragging and dropping the files into the Wasabi bucket interface.
  • Clicking “Upload Files” and selecting the files you want to upload.

However, if you need to back up large files and/or several files, this approach would be far too time-consuming to be useful. If you want to perform periodic backups, you need a solution that can automate the process and do so quickly and reliably.

How to Backup or Sync Synology to Wasabi with Synology Tools

If you have a large number of files, want to perform regular backups, or want to keep your Synology files synchronized with your Wasabi account, then you’ll need to use Synology Hyper Backup or Synology Cloud Sync.

Backup Synology Files with Synology Hyper Backup

Synology Hyper Backup is a Synology software that allows you to backup data (folders, system settings, and software packages) from your Synology devices to S3 cloud storage as well as to other external devices, local volumes, and rsync servers. You can clone full systems or retrieve select data with file-level recovery.

To backup your Synology files to Wasabi, use the following steps:

Step 1: Navigate to the Hyper Backup wizard and choose the S3 storage option.

  • Connection Name: Name your connection (this will display on your Connection List).

  • Local Path: Select the local folder on your Synology device.

  • Remote Path: Select the remote folder in the Wasabi cloud.

  • Sync Direction: Select the type of sync you want. You can create a bidirectional sync (both folders will remain synchronized with each other), download remote changes only (files in the Wasabi folder will sync to your Synology folder), or upload local changes only (files in your Synology folder will sync to your Wasabi folder).

  • Data Encryption: Check this box to enable client-side data encryption.

  • Schedule Settings: Create a file syncing schedule.

Step 5: Click “Apply” to save your settings.

Why Resilio Connect Is The Best Backup and Sync Solution

While each of the three methods listed above is suitable for backing up Synology files to Wasabi, Resilio Connect is the best solution for organizations that need a reliable, secure, and automated method of moving, syncing, and backing up enterprise data (i.e., large files and large numbers of files) for hybrid and multi-cloud scenarios.

Resilio is the best solution because it:

  • Is flexible and easy to manage.
  • Syncs in real-time or on a set schedule.
  • Provides fast, reliable transfers and synchronization.
  • Optimizes file transfers over any network (regardless of latency or quality).
  • Protects data with bulletproof security features.

Resilio Enables Scheduled and Real-Time Synchronization

Using Resilio’s Management Console, you can easily configure backup and sync jobs to occur in real-time or on a set schedule. 

Resilio uses real-time notification events from the host OS and optimized checksum calculations (i.e., identification markers for files that change when a change is made to a file) to immediately detect and replicate only the changed portions of a file.

Resilio also enables you to create bandwidth allocation profiles that control how much bandwidth is allotted to each endpoint at certain times of the day and on certain days of the week. You can use this feature to ensure each endpoint has the appropriate amount of bandwidth during scheduled backups/syncs while optimizing costs and resource allocation.

Resilio Provides Fast, Reliable Transfers and Synchronization

Most file transfer solutions use a point-to-point replication architecture deployed in one of two configurations:

  • Hub-and-spoke: This model consists of a hub server and multiple remote servers. The remote servers can’t transfer files directly to each other. All transfers must first go to the hub server, which then transfers files to each remote server one by one.

  • Follow-the-sun: In this model, file transfers occur from one server to another sequentially — i.e., Server 1 transfers to Server 2; Server 2 then transfers to Server 3; and so forth.

In simple scenarios (such as backing up one Synology NAS to one Wasabi bucket), point-to-point replication is suitable. But when you need to replicate data across multiple cloud or on-premises endpoints, it suffers from considerable weaknesses.

Both types of point-to-point replication create single points of failure. If any endpoint or network goes down, it can delay replication for every other endpoint in your environment. Replication speed is only as fast as your slowest endpoint.

And since replication can only occur between two servers at a time, syncing a large environment can take a long time.

Resilio Connect uses a P2P (peer-to-peer) replication architecture to sync files. With P2P replication, every endpoint can share files directly with every other endpoint. And every endpoint can transfer files simultaneously, enabling you to:

Achieve Blazing Fast Synchronization Speeds

Imagine you want to sync a file across five endpoints. Resilio Connect uses a process known as file chunking to split that file into multiple chunks that can transfer independently of each other. 

Endpoint 1 can share a file chunk with Endpoint 2. As soon as it receives the first file chunk, Endpoint 2 can immediately share it with Endpoint 3. Soon every endpoint will be sharing file chunks concurrently, allowing you to sync your environment 3–10x faster than with point-to-point solutions.

Our engineers were able to transfer a 1 TB payload across Azure regions in 90 seconds.

Sync Reliably

P2P replication also eliminates single points of failure, since every endpoint can share files directly with every other endpoint. If, for example, any endpoint goes down, the necessary files or services can be retrieved from any other endpoint.

Resilio also ensures files always reach their destination through:

  • Checksum restarts: Resilio retries transfers until they’re complete. And if a transfer is interrupted midway, Resilio can perform a checksum restart and resume the transfer at the point of failure.

  • Dynamic rerouting: Resilio can dynamically reroute around downed endpoints and networks, and always finds the optimal route to transfer your data to its destination.

Sync in Any Direction

Because of their point-to-point architecture, most file transfer solutions can only sync one-way or two-way.

But Resilio’s P2P architecture allows you to sync in any direction, such as:

  • One-way: Migrate files to any cloud or on-premises data centers. Or perform regular backups to any cloud or on-prem endpoint.

  • Two-way: Keep two endpoints synchronized with each other for redundancy or remote/distributed collaboration.

  • One-to-many: Distribute files or software updates to many geographically distributed endpoints, such as a fleet of vehicles.

  • Many-to-one: Consolidate data from many geographically distributed endpoints to one location (such as collecting performance data from a fleet of vehicles).

  • N-way: Sync data across many endpoints (even thousands of endpoints) simultaneously.

Resilio’s N-way sync capability is another key to its superiority over other file transfer and sync solutions. It can be used to optimize workflows for many use cases, such as:

1. Disaster Recovery Strategies

In the event of a disaster, organizations need to quickly bring their systems back online with the most current version of their data possible.

Because files can be synchronized across every endpoint in your environment and each endpoint can share files directly with any other endpoint, Resilio allows you to achieve:

  • Active-Active High Availability: Resilio effectively turns every endpoint in your environment into a backup server, enabling you to configure Active-Active HA for load-balancing and faster recovery.

  • Active-Passive High Availability: You can create an Active-Passive cluster, configuring failover to any other endpoint in your environment.

  • Sub-five-second RPOs: With real-time replication enabled, you can achieve sub-five-second RPOs.

  • RTOs within minutes of an outage: When a disaster occurs, every endpoint can work together to bring your entire system back online so you can bring your system back online in minutes, not hours.

Hot/Live DR: Multi-site Active/Active; Warm DR: Active/Active; Cold DR: Active/Passive; Offsite Copy: Backup Copy

For example, a global construction company uses Resilio Connect to support continuous Active-Active high availability across all sites (one on-premises core and two Azure endpoints), reduce recovery times for planned and unplanned outages, and reduce time-to-desktop for their VDI (learn more about how they do it here).

2. Remote and Distributed Workforces

Organizations that have remote/distributed workforces that collaborate on files need to ensure that everyone has access to the most up-to-date versions of files.

Using Resilio’s real-time replication and N-way sync features, any change made by any employee located anywhere in the world can be immediately synchronized across every other endpoint in your organization. This ensures everyone is working on the same files and eliminates bottlenecks from your workflows.

Resilio also provides granular control over synchronization so you can ensure files are only synced to necessary endpoints, allowing you to automate workflows and minimize data transfer costs.

When the COVID-19 pandemic hit, Skywalker Sound used Resilio Connect to facilitate their switch to a remote workforce. Resilio enables them to securely and efficiently sync data across remote sites in order to optimize workflows for their distributed teams (learn more about how here).

3. Software Update Distribution

Since every endpoint can share files simultaneously, you can quickly distribute large software updates across many cloud and on-premises endpoints and reduce distribution time.

VoiceBase (a speech-to-text transcription software) uses Resilio to distribute speech model updates (50+ GB files) across 400+ production servers in 88% less time than their previous solution (read more about how they do it here).

Scale Organically

Point-to-point solutions inherently suffer from slow replication speeds and single points of failure. And these issues are exacerbated at scale — i.e., when syncing large files, large numbers of files, or syncing across many endpoints.

But Resilio’s P2P architecture enables it to thrive in such scenarios. 

Resilio can sync files of any size, type, or number (our engineers successfully synced 450+ million files in a single job). 

And Resilio also scales organically. Since every endpoint can share files with every other endpoint simultaneously, adding more endpoints only increases sync speed and resources. 

Using horizontal scale out replication, Resilio clusters can work together to achieve transfer speeds of 100+ Gbps per cluster.

Resilio’s Proprietary Transfer Protocol Optimizes Transfers Over Any Network

Most file sync and transfer solutions don’t use WAN optimization protocols. Instead, transfers over all networks occur with inefficient protocols, such as TCP.

While TCP works well over LANs, one of the many problems with TCP transfer is that it treats packet loss as a network congestion issue and reduces transfer speeds in response. But packet loss is a defining characteristic of WAN transfer, so reducing transfer speed is unnecessary. 

Resilio Connect uses a proprietary UDP-based WAN acceleration protocol known as Zero Gravity Transport™ (ZGT). 

ZGT uses a congestion control algorithm that constantly probes the Round Trip Time (RTT) of a network to identify and maintain the ideal data packet send rate. It intelligently analyzes the underlying network conditions (by measuring latency, packet loss, and throughput over time), automatically adjusts to maximize utilization of the internet connection, and adapts to conditions in real-time.

ZGT also uses interval acknowledgements (acknowledging packet receipt in groups) and delayed retransmission (retransmitting lost packets in groups once per RTT) to reduce traffic over the network and optimize transfer speeds. 

With ZGT, you can replicate files over any type of connection, such as VSAT, cell (3G, 4G, and 5G), Wi-Fi, and any IP connection. 

This enables organizations to ingest data from edge devices (such as IoT data ingestion) and even from the far edge (such as at sea or in countries with poor network coverage). 

For example, healthcare company Shifo uses Resilio Connect to ingest and distribute data across communities with underdeveloped network infrastructure, like Uganda (learn more about how they do it here).

  • Adjust replication parameters, such as disk I/O, buffer size, and data hashing.

  • Create bandwidth profiles that govern how much bandwidth each endpoint is allocated.

  • Automate replication jobs and script any type of functionality using Resilio’s REST API.

  • Automate troubleshooting tasks, such as file conflict resolution.

MixHits Radio — a music streaming service that provides music for businesses such as Dunkin Donuts and McDonald’s — uses Resilio Connect to sync music metadata across their servers in real-time and provide a seamless listening experience for their customers. Resilio handles this process reliably and automatically, enabling them to go from “spending 15 hours on average per week troubleshooting conflicts… to spending no time at all with Resilio.” (Learn more here.)

Resilio Provides Bulletproof Security

Most other file transfer and sync solutions don’t include built-in security features, forcing users to invest in 3rd party security tools and VPNs.

Resilio includes native security features that protect your data at rest and in transit, such as:

  • End-to-end encryption: Resilio encrypts data using AES-256-bit encryption.

  • Cryptographic data integrity validation: Resilio uses integrity validation to ensure your data arrives intact and uncorrupted.

  • Mutual authentication: Resilio requires each endpoint to provide an authentication key before receiving any files, ensuring your data is only delivered to approved endpoints.

  • Permission controls: You can control who is allowed to access specific files and folders.

  • Forward secrecy: Every session is protected with a one-time session encryption key.

  • Immutable copies: Resilio stores immutable copies of files in the cloud to protect you from data loss in the event of ransomware.
Mutual Authentication: Data is only delivered to designated endpoints; In-Transit Encryption: Data can't be intercepted or hacked; Integrity Validation Process: Ensures data remains intact
