PROTECTING YOUR DATA
• Rapid recovery from file system corruption without affecting availability.
• Resilient against power outage corruption.
• Periodic checksum validation of file system metadata.
• Improved data integrity protection.
• ReFS remains online during subdirectory reconstruction and knows where orphaned subdirectories exist andautomatically reconstructs them.
• Ideal for file server volumes.
Protecting files and directories: File system enhancements NTFS improvements
• Rapid recovery from file system corruption without affecting availability
• Data corruption virtually eliminated through allocate-on-write
• Period checksum validation of file system meta-data
• Seamless data integrity protection
Resilient File System (ReFS) • Seconds to fix corrupted data.
• No offline time when used with CSV.
• Disk scanning process separated from repair process.
• Online scanning with volume and offline repair.

PROTECTING YOUR DATA
Disk resiliency with storage spacesSimple• Data is striped across disks.
Mirror• Data mirrored to a duplicate disk.• Two and three-way mirroring.• Mirrored configuration with
clustering for workloads.
Parity• Data striped to all-but one of the
disks. The remaining disk contains a checksum bit enabling data to be generated for a failed disk.
• Parity with clustering for archives.

Once Hyper-V Replica is enabled, VMs begin replication
• Affordable in-box business continuity and disaster recovery
• Configurable replication frequencies of 30 seconds, 5 minutes and 15 minutes
• Secure replication across network• Agnostic of hardware on either site• No need for other virtual machine
replication technologies• Automatic handling of live migration• Simpler configuration and
management
Replicate Hyper‑V VMs from a Primary to a Replica site

Hyper-V Replica | Extended Replication
• Once a VM has been successfully replicated to the replica site, replicacan be replicated to a 3rd location
• Chained Replication
• Extended Replica contents match the original replication contents
• Extended Replica replication frequencies can differ from original replica
• Useful for scenarios such as SMB -> Service Provider -> Service Provider DR Site
Replicate to 3rd Location for Extra Level of Resiliency

Replication can be enabled on the 1st replica to a 3rd site

Hyper-V Recovery Manager
• Protect important services bycoordinating replication and recovery of VMM-managed private clouds
• Automates replication of VMs within clouds between sites
• Hyper-V Replica provides replication, orchestrated by Hyper-V Recovery Manager
• Can be used for planned, unplanned and testing failover between sites
• Integrate with scripts for customization of recovery plans
Orchestrate protection and recovery of private clouds
