Next-generation data protection and integrityWhen dealing with large-scale data storage, businesses require a solution that offers reliable backup and prevents file corruption. With support for the next-generation Btrfs file system, RS3617xs+ ensures information is stored with a high level of data integrity, while providing flexible and efficient data protection tools. See the white paper for more technical details regarding Btrfs and data protection.Fast and efficient snapshotsSnapshots preserve the history of a shared folder allowing you to save up to 1024 backup copies for point-in-time recovery. Snapshots can be automatically captured up to every 5 minutes, without noticeably impacting system performance.Metadata mirroring and survivabilityBtrfs file system stores two copies of critical metadata on a volume, improving the availability and ensuring the integrity of your file system.Corruption detection and correctionBtrfs generates checksums for data and metadata, and then verifies the checksums during each read process to ensure the integrity of the filesystem and files. If the file system discovers a mismatch, metadata will be repaired to keep file system consistent. In the meantime, corrupted files will be reported and logged.Customizable quotas for shared foldersWith Btrfs, you can specify a storage limit for each shared folder, making it possible to precisely control space consumption when multiple teams or departments save files on the same Synology NAS server.Seamless storage solution for virtualization environmentsRS3617xs+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, Hyper-V, and OpenStack Cinder. With VMware vSphere 6 and VAAI integration certified, RS3617xs+ helps offload specific storage operations and optimizes computation power for unparalleled performance and efficiency in VMware environments. As the centralized storage of a virtual environment, RS3617xs+ enables virtual machine migration, allowing movement from server to server whilst eliminating service downtime and disruption to user. Windows Offloaded Data Transfer (ODX) and Synology Advanced LUN support greatly improves the efficiency on massive data transfer and migration. With OpenStack Cinder support, RS3617xs+ can be used as a block-based storage component for servers complying with the Cinder API.
