App Center ecosystem extends NAS functionality
Apps for backup/sync, virtual machines/containers, content management, productivity, and more 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, conserve storage capacity, and optimize performance. For example, if 20 virtual machines on a NAS are replicated using the same template, then storage space requirements for all 20 virtual machines can be reduced by up to 95%. Whether acting 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 both random write performance and SSD lifespan.


More SSD performance and lifespan optimization technologies
Write Coalescing
Transforms all random writes to sequential writes along with reduced I/O, effectively increasing write performance in all-flash environments.

Pool Over-provisioning
Dedicated space can be flexibly reserved in an SSD storage pool to allow new data to be written into a complete block even if the pool is almost full, thus improving the performance of fragmented pools.

TRIM
Allows QuTS hero to inform SSDs to delete unneeded data blocks and process the deletion tasks during system idle times, meaning it does not have to wait for when new data is 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 destination. If the primary NAS goes offline, IT staff can simply adjust the privilege settings of the secondary NAS to ensure continuous operations. SnapSync provides the strongest support for nonstop business operations and helps users to reduce the risk of data loss.

Snapshots multiply backup protection
Attain peace of mind with near-limitless, instant snapshots. Copy-on-write technology makes snapshot creation almost instantaneous without affecting ongoing data writing. Snapshot Replica replicates snapshot files to the backup NAS, simplifying data protection with version control.

HBS simplifies 3-2-1 backup plans
HBS centralizes backup, restoration, and synchronization for easily transferring data in the TS-h2490FU to another QNAP NAS, remote server, or cloud storage space. HBS supports QuDedup technology that eliminates redundant data at the source and makes multi-version backup faster.
