In their own words
JetStream DR
JetStream DR provides continuous data protection and disaster recovery for VMware workloads. It replicates VM data to object storage, with a stated recovery point objective of near zero, and says it can bring VMs back online within minutes using recovery clusters provisioned on demand. It captures data through VMware vSphere I/O Filters and is managed from a vCenter plug-in or the vSphere Web GUI. Protected VMs do not need installed agents or snapshots, according to the maker. Listed targets include S3-compatible storage such as AWS S3, Azure Blob Storage, Cloudian, and MinIO, as well as Azure NetApp Files. Its hypervisor-level software supports on-premises SAN, NAS, vSAN, and HCI environments, with VMware-compatible recovery infrastructure. Coverage is listed for vSphere 7 and 8, with hybrid deployment, cloud backup targets, and off-site replication. JetStream DR for AVS is obtained through Azure Marketplace; on-premises installations use an OVA from JetStream support. The company describes the product as built for service providers supporting customers’ on-premises continuity needs.
XtreemFS
XtreemFS is a free, fault-tolerant distributed file system for general-purpose storage, available for Linux, macOS, Windows and self-hosted deployments. Files are replicated across storage servers, with automatic failover to a backup replica if the primary fails. Full or partial read-only replicas support immutable files and can be used to create caches across datacenters. The project says an installation can grow to thousands of storage and metadata servers by adding or removing storage servers. POSIX compatibility makes it usable as an NFS replacement. SSL and X.509 certificate support are built in, and the site says XtreemFS can run over the internet without a VPN. A Hadoop client supports use as an HDFS replacement. Listed uses include filer replacement, HPC and Hadoop clusters, VM block storage and cross-branch sharing. Linux distribution packages and precompiled Windows and Mac OS X clients are available. The FAQ says a single volume may hold up to tens of millions of files, with no known limits stated for volumes and services. The project is open source under a BSD license and is developed by Zuse Institute Berlin.
