Establish a Strong Storage Foundation with Btrfs

DS1520+ features a Btrfs file system optimized by Synology to offer you high reliability and high performance. Btrfs supports advanced storage technologies that meet the needs of modern business :

Advanced snapshot technology provides schedulable and near-instantaneous data protection of shared folders and LUNs.

File and folder level data restoration offers users who wish to restore only a specific file or folder more flexibility.

Flexible Shared Folder and User Quota System provide comprehensive quota control on all user accounts and shared folders.

File self-healing allows Btrfs file systems to auto-detect corrupted files using mirrored metadata and to recover broken data using RAID configurations.

Inline compression compresses data before writing them to the drive, to optimize storage use and reduce write commands to the drives.

Full Backup Suite

DS1520+ offers users a range of backup solutions for cloud and physical, on-premises environments. Backing up and restoring data is effortless – and completely free of licenses on compatible NAS models :

Back up your cloud data : Cloud Sync enables users to seamlessly back up or synchronize data between a local Synology NAS and other cloud services.

Back up your PCs and servers : Synology Drive Client backs up your Windows®, macOS®, and Linux® desktop devices to safeguard important computer files.

Back up your Synology NAS : Hyper Backup offers a wide range of destinations for backups of your NAS, including on-premises and cloud.

 

Running & Protecting Virtual Machines

Synology Virtual Machine Manager (VMM) is an intuitive hypervisor application that lets users easily set up virtual machines and run operating systems including Windows®, Linux®, and Virtual DSM. With VMM, users can build up a cluster environment with multiple Synology systems while keeping the flexibility to scale out online and migrate virtual machines for load balancing and resource allocation. Disaster recovery features including instant snapshot, replication, cloning, restore and failover help you fully protect each virtual machine and safeguard your digital assets at no additional cost.

VMM Pro licenses give access to advanced features including remote replication, remote storage migration, high availability and live migration, helping users further minimize the risk of service downtime and manage IT resources with maximum flexibility.

Automated Video Surveillance System

With Synology Surveillance Station, DS1520+ can act as a full-featured video surveillance system. Simply add network-connected cameras and you can monitor their live feeds, play back recordings, and receive instant event alerts right away.

Works with more than 7,300 IP cameras : Pick any compatible model that suits your requirements and budget, or use the LiveCam app to turn an old smartphone into an IP camera.

No subscription fee : Unlike security cameras that require monthly cloud storage subscription, all your recordings are stored on the DS1520+, 100% under your control.

Remote monitoring & control : Access your surveillance system from a web browser, the desktop client, or the DS cam mobile app anytime, anywhere.

Automation & notification : Set up rules to trigger specific actions when predefined events occur, such as automatically taking snapshots when motion is detected. Get notified by email, SMS, or push notification so that you can intervene in time.
