Keep disaster at bay
Hyper Backup A comprehensive backup and recovery solution for securing data stored on Synology servers. Backup data locally to another Synology device rsync server or cloud-based storage such as Google Drive Dropbox S3-compatible destinations and Synology C2. Deduplication integrity checks and incremental transfer technology reduce bandwidth and storage used. Learn more Snapshot Replication Easily schedule flexible point-in-time backups of shared folders and iSCSI LUNs with an RPO as low as 5 minutes and recovery in seconds. Set up replication and failover to other Synology storage systems for fast RTOs and minimal service disruption. Learn more Active Backup Suite Enables administrators to easily backup the entire IT infrastructure to their NAS including Windows & Linux workstations and servers file servers VMware and Hyper-V virtual machines and Microsoft 365 and Google Workspace accounts. Backups benefit from deduplication multiversioning and optimizations to reduce bandwidth and storage used. Learn more |
