App Center Ecosystem Extends NAS Functionality
Apps for backup/sync, virtual machines/containers, content management, productivity, and other features can be used to expand the application potential of the TS-h2490FU.

Inline Data Deduplication, Compression, and Compaction Improve SSD Endurance
QuTS hero supports advanced block-based data reduction technologies (including inline data deduplication, compression, and compaction) to reduce file sizes, save storage capacity, and optimize performance. For example, if 20 virtual machines are replicated on a NAS using the same template, the storage requirements for all 20 virtual machines can be reduced by up to 95%. Whether as primary or backup storage, the TS-h2490FU optimizes storage utilization to provide a reliable storage cornerstone in the Big Data era. All-flash solutions thus achieve higher cost-efficiency while improving random write performance and SSD lifespan.


Optimization Technologies for Higher SSD Performance and Lifespan
Write Coalescing
Converts all random writes into sequential writes with reduced I/O, effectively increasing write performance in all-flash environments.

Pool Overprovisioning
Dedicated storage space can be flexibly reserved in an SSD storage pool, allowing new data to be written to a complete block even when the pool is almost full, improving the performance of fragmented pools.

TRIM
Enables QuTS hero to instruct SSDs to delete unneeded data blocks and handle erasure tasks during system idle times, meaning it doesn't have to wait for new data to be written to the block.

Real-time SnapSync Ensures Minimal RPO with Real-time Disaster Recovery
Real-time SnapSync ensures that both the primary and secondary NAS maintain identical data. When data is written to the source, it is immediately written to the target. If the primary NAS goes offline, IT staff can simply adjust the permission settings of the secondary NAS to ensure continuous operation. SnapSync provides the strongest support for uninterrupted business operations and helps users reduce the risk of data loss.

Snapshots Multiply Backup Protection
With nearly limitless, instant snapshots, you no longer have to worry. Thanks to copy-on-write technology, snapshot creation is performed almost instantaneously without affecting the ongoing writing of data. Snapshot Replica replicates snapshot files to the backup NAS, simplifying data backup with version control.

HBS Simplifies 3-2-1 Backup Plans
HBS centralizes backup, restoration, and synchronization for easy transfer of data from the TS-h2490FU to another QNAP NAS, a remote server, or cloud storage. HBS supports QuDedup technology, which eliminates redundant data at the source and accelerates multi-version backup.
