help SIOS DataKeeper FAQ

What does SIOS DataKeeper replicate?

SIOS DataKeeper provides software-based block-level replication for servers and virtual machines. It can replicate data synchronously or asynchronously between supported environments, including VMware vSphere, Microsoft Hyper-V, and Nutanix deployments.

Can SIOS DataKeeper work with Microsoft Failover Clustering?

Yes, SIOS DataKeeper is commonly used with Windows Server Failover Clustering when shared storage is not available or when local storage must be mirrored between nodes. The cluster configuration and supported Windows versions should be checked against the current SIOS compatibility list.

Does SIOS DataKeeper replace backups?

No, replication keeps a second copy current for availability and failover but can also copy accidental deletion or corruption. A separate backup system with older recovery points is still needed for file recovery and ransomware response.

How is SIOS DataKeeper different from Zerto?

SIOS DataKeeper is closely tied to server clustering and volume replication, especially in Windows and virtualization environments. Zerto is a separate disaster recovery platform centered on continuous journal-based replication and recovery orchestration for virtualized workloads.
