Incremental backup: Block-level incremental backup reduces storage required by only backing up the differences between versions.

Deduplication: Applies to cross-version backups as well as files that are simply renamed or duplicated, thereby saving space and consuming less time and money.

Snapshot technology: Leveraging the Btrfs file system, snapshot technology allows for flexible point-in-time recovery of files with only a fraction of storage space and computing resources.

Self-recovery: With eligible privilege, operators can recover files on their own with Synology File Station or Windows File Explorer, without the intervention of system administrators.

Off-site replication : Replicate data to another destination by taking and sending snapshots to another server, and further manage the schedule and retention rules according to your plan.

High availability: Combine two identical NAS into one high-availability cluster, providing a complete hardware and data redundancy solution in case of unforeseen accidents.
