Efficiently Back Up Terabytes of Data with Synology
How to Back Up Terabytes of Data Efficiently with Synology NAS
As organizations generate increasing amounts of data from large media files to project archives, virtual machines, databases, and compliance records, the need to back up terabytes (and even petabytes) efficiently becomes a core operational priority. Traditional backup tools often struggle with scale, speed, and reliability, especially when data sets grow beyond what desktop drives or basic cloud sync tools can handle.
Synology NAS provides a powerful, flexible, and scalable platform specifically designed to back up massive data volumes efficiently. With proper configuration and a smart strategy, businesses can protect large datasets without performance bottlenecks or excessive storage overhead.
Why Synology Excels at Large-Scale Backups
Synology NAS is engineered to support enterprise-grade storage operations. It offers high-capacity drive bays, SSD caching, multi-gigabit networking, and intelligent backup tools, allowing businesses to build fast, resilient backup systems that scale effortlessly.
Key advantages for large backups:
High-capacity storage pools with up to dozens of HDD/SSD bays
RAID and Synology Hybrid RAID (SHR) for redundancy and performance
10GbE and link aggregation options for high-throughput transfers
Snapshot technology for rapid incremental backups
Hybrid cloud integration with Synology C2
These capabilities make Synology one of the most efficient platforms for handling multi-terabyte backup workloads.
Step 1: Design a High-Performance Storage Architecture
Efficient backup starts with the right NAS hardware and configuration.
Choose the right Synology model.
For multi-terabyte environments, use rackmount or high-bay desktop systems such as RS3621xs+, DS3622xs+, or similar models designed for heavy workloads.
Optimize your RAID configuration.
Use RAID 6 or SHR-2 for large arrays to maximize protection against multi-drive failures, a critical concern when using many large-capacity drives.
Enable SSD caching or NVMe acceleration.
This dramatically improves read/write speeds during large backup jobs.
Separate workloads into multiple volumes
Keeping backups on dedicated volumes prevents performance conflicts with production data.
Step 2: Use Synology’s Efficient Backup Tools
Synology provides several integrated tools to optimize large-scale backups.
Hyper Backup
Best for backing up NAS data to:
External drives
Another Synology NAS
Remote servers
Synology C2 Cloud
It uses incremental backups and deduplication, which saves time and bandwidth when handling large datasets.
Active Backup for Business
Ideal for backing up:
Windows servers
Linux servers
Virtual machines
NAS shares
Workstations
This tool supports global deduplication, meaning terabytes of repetitive data only need to be stored once.
Snapshot Replication
Perfect for environments requiring:
Sub-minute recovery points
Ransomware-resistant backups
Fast local rollback
Snapshots scale exceptionally well with large data volumes because they only record changed blocks, not entire files.
Step 3: Optimize Network Throughput for Faster Backups
Backing up terabytes of data requires high-speed networking to avoid long transfer times.
Best practices include:
Upgrading to 10GbE or using link aggregation on compatible NAS models
Using CAT6 or fiber cabling for high-bandwidth connections
Segmenting backup traffic onto a dedicated VLAN
Ensuring switches support adequate throughput and jumbo frames
A properly optimized network can reduce multi-terabyte backup windows from days to hours.
Step 4: Implement a Hybrid Backup Strategy
For complete protection, combine local and off-site backups.
Local backup
Fast restores for:
VM failures
Ransomware rollback
Accidental deletions
Offsite backup using Synology C2 or remote NAS
Protection against:
Fire, flood, or hardware loss
Large-scale ransomware incidents
Physical theft or environmental damage
Using both ensures compliance with the 3-2-1 rule:
3 copies of data, 2 media types, 1 stored offsite.
How Epis Technology Enhances Large-Scale Synology Backup Deployments
Epis Technology helps businesses design and deploy Synology environments engineered specifically for backing up terabytes of data efficiently. The team evaluates current data volumes, network capacity, RAID layout, and RPO/RTO objectives, then creates a scalable backup architecture tailored to your needs. Epis Technology configures storage pools, sets up Active Backup and Hyper Backup policies, deploys snapshot protection, and integrates cloud services like Synology C2 for off-site resilience. Ongoing monitoring, optimization, and restore testing ensure your backup system performs reliably as data volumes grow. With professional guidance, your Synology NAS becomes a powerful, streamlined platform for large-scale data protection.
Step 5: Test Restores Regularly
A backup is only valuable if it can be restored quickly and accurately.
Test:
Full file-level restores
VM restores
Snapshot rollbacks
Offsite recovery from C2 or remote NAS
Routine testing ensures your multi-terabyte backup strategy works when you need it most.
