SIOS Protection Suite
SIOS Protection Suite provides high availability clustering, data replication, and disaster recovery for business-critical applications, databases, and ERPs.
What SIOS Protection Suite is
SIOS Protection Suite provides high availability clustering, data replication, and disaster recovery for business-critical applications, databases, and ERPs. Its Linux suite can build SAN or SANless clusters for Linux applications on cloud or on-premises physical and virtual servers. Application Recovery Kits monitor application health and automate recovery, with kits varying by edition. For Linux, configurable recovery policies manage failover, while continuous block-level replication helps protect data. SIOS lists AWS and Microsoft Azure evaluation guides for the Linux suite. The product supports workloads including Oracle, SQL Server, PostgreSQL, NFS, SAP, and SAP HANA, with hybrid deployment and multi-site replication. SIOS documentation lists Protection Suite for Windows 10.1 as current and includes Windows support matrices and recovery-kit documentation. The company was founded in 1999 and is headquartered in San Mateo, California. Pricing is available on request, and SIOS offers a 14-day trial; the trial page also invites Windows and Linux trial requests without specifying a duration there.
