# Sendense - Universal Backup Platform

> Sendense is an enterprise backup and disaster recovery platform that enables cross-platform VM protection between VMware, CloudStack, OSSEA, Azure, and physical workloads.

## What Sendense Does

Sendense provides:
- **What Is Sendense**: Plain-language overview of Sendense backup, one-off migration licensing, Enterprise Block Archive, AsureDense recovery proof, cross-platform restore, and the SNA/SHA/SCA architecture (`https://sendense.com/what-is-sendense`)
- **Sendense Components**: Public definitions for SHA, SNA, SNAgent, Enterprise Block Archive and the Sendense Controller Template, with concise responsibilities for each role (`https://sendense.com/docs/components`)
- **CloudStack Backup**: CSP/MSP-focused CloudStack KVM backup with agentless CBT-enabled protection for QCOW2/NFS, ZFS and Linstor/DRBD, plus Universal Client coverage for other CloudStack block storage and EBA dedupe for retained repository efficiency (`https://sendense.com/cloudstack-backup`)
- **Live Replication**: VMware to CloudStack/OSSEA/Azure with 5-minute RTO failover
- **VMware Ecosystem**: Protect VMware workloads with fast incremental backup, flexible DR targets, EBA repository efficiency, AsureDense validation evidence, and migration continuity (`https://sendense.com/ecosystem/vmware`)
- **Azure Ecosystem**: Protect Azure VMs, use Azure as a DR target, archive to Blob storage, reduce standby compute cost, and preserve cross-platform recovery evidence (`https://sendense.com/ecosystem/azure`)
- **DR at Scale**: Hot standby disaster recovery with test, planned, and emergency failover modes, multi-site readiness tracking, and CloudStack/OSSEA/Azure recovery targets (`https://sendense.com/solutions/dr-at-scale`)
- **Flexible DR**: Storage-cost disaster recovery with S3-compatible backup, EBA repository efficiency, AsureDense evidence, and on-demand restore to CloudStack, OSSEA, Azure, VMware, or another supported target (`https://sendense.com/use-cases/flexible-dr`)
- **Backup & Replication**: Unified backup and replication for VMware, CloudStack, OSSEA, Azure and physical workloads with EBA efficiency, AsureDense proof, S3-compatible archive and portable restore paths (`https://sendense.com/solutions/backup-replication`)
- **Backup to S3**: Cost-effective disaster recovery at storage costs, not compute costs
- **Integrations**: Sendense storage, platform, application and identity integrations, including Impossible Cloud, CloudStack, OSSEA, Azure, SQL Server and Active Directory recovery paths (`https://sendense.com/integrations`)
- **Impossible Cloud Integration**: Use Impossible Cloud as a primary or secondary Sendense repository target, with EBA reducing object storage footprint, transfer volume and backup copy time. Example models use Impossible Cloud storage at EUR 7.99 per TB/month and a 90% EBA footprint reduction (`https://sendense.com/integrations/impossible-cloud`)
- **Compliance Evidence**: Backup and DR audit support with AsureDense recovery evidence, access audit trails, credential vault activity, immutable retention, legal hold, controlled deletion, and exportable audit packs (`https://sendense.com/use-cases/compliance`)
- **Cross-Platform Restore**: Restore backups to any supported platform with inline VM conversion
- **Break Vendor Lock-In**: Portable recovery across VMware, CloudStack, OSSEA, Azure, or another supported target with inline conversion, preserved backup history, EBA repository efficiency, and AsureDense proof (`https://sendense.com/use-cases/break-lock-in`)
- **VMware Exit**: Migrate from VMware to CloudStack, OSSEA, or Azure while preserving backup history, recovery evidence, EBA retention, and destination DR protection (`https://sendense.com/solutions/vmware-exit`)
- **Cut VMware Costs**: Reduce VMware spend through backup replacement, open DR targets, or a protected CloudStack/OSSEA exit path while preserving recovery evidence and using EBA software-defined repository efficiency instead of separate dedupe/archive appliance hardware (`https://sendense.com/use-cases/cut-vmware-costs`)
- **Service Providers**: Build BaaS, DRaaS, VMware exit, and managed cloud services with SCA tenant-aware fleet control, EBA repository efficiency, billing-ready telemetry, and CloudStack or OSSEA recovery targets (`https://sendense.com/use-cases/service-providers`)
- **MSP Revenue**: Package managed BaaS, DRaaS, VMware exit, and managed cloud services with SCA fleet control, EBA storage efficiency, usage telemetry, and CloudStack/OSSEA targets (`https://sendense.com/solutions/msp-revenue`)
- **OSSEA Partnership**: Protect OSSEA workloads with native Sendense backup, cross-instance DR, VMware or Azure migration, EBA repository efficiency, and AsureDense recovery evidence (`https://sendense.com/partners/ossea`)
- **CloudStack Platform**: Native CloudStack backup across Linstor, ZFS and QCOW2 on NFS with agentless CBT-enabled paths, Universal Client coverage for other block storage, tenant-aware operations, EBA retention and service provider delivery paths (`https://sendense.com/platform/cloudstack`)
- **Platform Architecture**: Disaggregated SNA, SHA and SCA architecture with outbound-only site paths, central hub control, EBA repositories and multi-tenant fleet management (`https://sendense.com/platform/architecture`)
- **Security Architecture**: Repository isolation, outbound-only connectivity, immutable EBA retention, credential vaulting, RBAC and audit-ready recovery evidence for ransomware resilience (`https://sendense.com/platform/security`)
- **Mobility**: Cross-platform VM movement, one-off migration paths, driver conversion, protected landing zones and portable recovery across supported VMware, CloudStack, OSSEA and Azure targets (`https://sendense.com/platform/mobility`)
- **AsureDense**: Automated proof-of-recovery evidence attached to every recovery point, including integrity checks, mount inspection, boot screenshots and audit-ready validation records (`https://sendense.com/platform/asuredense`)
- **Clean Room**: Isolated, lease-bound recovery validation - boot full application stacks from backup into a sealed network, validate services, and capture auditable evidence without production exposure (`https://sendense.com/platform/clean-room`)
- **Enterprise Block Archive (EBA)**: Immutable, deduplicated repository storage with controller-managed SSD writeback tiering when suitable SSD media is available, direct restores without full archive rehydration, legal hold/retention controls, and reduced external S3-compatible archive writes (`https://sendense.com/platform/eba`)
- **Item-Level Recovery and Indexing**: Search files across indexed servers, review file version timelines, browse Active Directory objects, and recover SQL databases or tables without full VM restores (`https://sendense.com/platform/item-level-recovery`)
- **Sendense vs Veeam**: Compare value beyond license price: EBA repository economics, up to 90% external S3 reduction, open DR and DRaaS targets, one-off migration paths, and distributed SNA/SHA/SCA architecture (`https://sendense.com/compare/veeam`)
- **Backup Storage Cost Comparison**: Model raw spinning repository, dedupe appliance and Sendense EBA economics for 720 TB and 1.44 PB effective backup capacity, including CSP payback (`https://sendense.com/compare/veeam-storage-costs`)

## Key Differentiators vs Veeam
