Edge storage for distributed teams 
Multi-endpoint data protection
Smart surveillance for small deploymentsEdge storage for distributed teamsProvide secure and convenient cross-platform file access, sharing, and synchronization across multiplelocations. Enable effective collaboration with Synology DriveSynology Drive provides remote data access, synchronization, on-demand file restoration, and backup via handy desktop and mobile applications. Multi-platform supportAccess personal and shared data from mobile app, desktop client, web browser, or another Synology system: Any changes you make are automatically synced to other devices as soon as they are connected. Collaborate in real timeIntegrate with Synology Office to enable concurrent editing on documents, spreadsheets, and slides, with support for conversion to and from Microsoft Word, Excel, PowerPoint, and OpenDocument files. Connect teams with Hybrid ShareUtilize Hybrid Share to store large sets of data in the cloud, leveraging the powerful bandwidth of our data centers to stream requested files to local NAS deployed at the branch offices. Data on-demandWith Hybrid Share-enabled folders, remote teams retain full access to the most up-to-date files while benefiting from reduced local storage footprint and bandwidth usage. Cache data used locallyFrequently-accessed files are kept on the local NAS, allowing users to access them at LAN speeds. Files and folders can also be pinned manually to prevent them from being replaced when the cache is full. Multi-endpoint data protectionDesign an effective backup strategy to maximize system availability with a host of native and license-free solutions. Endpoint, VM, and NAS/SAN protectionSecurely back up Windows and Linux endpoints, Synology servers, and VMware® and Hyper-V® virtual machines with Active Backup for Business. Microsoft 365 and Google WorkspaceCentralize backups of Microsoft 365 and Google Workspace data to protect it from accidents and simplify compliance with data retention policies. Schedulable backups, flexible file versioning, and block-level deduplication ensure flexibility and savings in terms of storage and bandwidth consumption. Hyper BackupBack up files, LUNs, installed applications, and system configurations to destinations including Synology C2 Storage, public cloud platforms, USB devices, file servers, local folders, or other Synology systems. Set and forget backup tasks with regular schedules, enhance security with granular user permissions and encryption, keep backup sizes small with built-in deduplication, and restore data flexibly with multi-versioning. Snapshot ReplicationSnapshot Replication enables configurable point-in-time snapshots of shared folders and VM storage with an RPO as low as 5 minutes and recovery within seconds. Smart surveillance for small deploymentsLeverage flexible deployment options, intuitive management capabilities, and advanced video analytics to secure your premises.
