PC, Mac, Server, VM, and NAS/SAN protection
Securely back up a wide range of systems including Windows, Mac, and Linux endpoints, VMware and Hyper-V virtual machines, and Synology servers. Expand protection to physical servers running Windows or Linux, as well as storage solutions such as Nutanix Files, NetApp ONTAP, and Windows Server with VSS (Volume Shadow Copy Service). Built-in deduplication technology optimizes storage efficiency, while multi-versioning capabilities provide flexible restoration options.

Microsoft 365 and Google Workspace
Centralize backups of Microsoft 365 and Google Workspace data to protect cloud data from accidents and simplify compliance with data retention policies. Schedulable backups, flexible file versioning, and block-level deduplication ensure flexibility and storage and bandwidth savings.

Advanced data protection and recovery

Efficient and reliable Synology system backup
Back up entire systems or all data, applications, and configurations to a wide range of storage destinations, including Synology C2 Storage. In case of data loss, quickly restore complete systems through bare-metal recovery or retrieve individual files as needed. Advanced features including automated scheduling, granular access controls, end-to-end encryption, data deduplication, and multi-version retention empower you to create the optimal backup plan for your data deployment.
