Automatic failover
Network ports supporting automatic failover eliminate single points of hardware failure, ensuring stable operation at all times.

Availability and protection
Synology High Availability (SHA)
Enable automatic minute-level failover by pairing up two FS2500 units to create a high-availability cluster, minimizing service downtime in the event of a server failure. Learn more
Snapshot Replication
Create point-in-time snapshots of LUNs and shared folders with an RPO as low as 5 minutes, with support for granular version control. Learn more
Hyper Backup
Back up files, LUNs, applications, and system configurations on your NAS to other Synology NAS, Synology C2 Storage, public cloud platforms, USB devices, file servers, or local folders.

Flash volume deduplication
Leverage volume-wide deduplication to remove duplicate data on all-flash arrays and greatly increase storage efficiency. Eliminate redundant data to save up to 65% of storage space use in applications like virtual desktop infrastructure and virtual machines.3
