Microsoft Hyper‑V continues to gain traction as organizations diversify beyond VMware and expand hybrid cloud deployments, and so does the attack surface that MSPs need to defend. The Arcserve ShadowProtect 8.0 release is purpose-built for modern Microsoft Hyper‑V environments with a host-based version. It's available now alongside agent-based backup; the general-purpose protection method MSPs already rely on across their environments (Hyper-V VMs included). Both are built for cyber resilience against ransomware and other disruptive events — the right fit depends on how your environment is structured today.
Host-based backup is a new, Hyper-V-native protection model in ShadowProtect 8.0. Backups can now be managed directly at the Microsoft Hyper-V host level for the first time.
Host-based ShadowProtect deployment provides:
Automatic VM discovery: all guest VMs on the host are auto-listed, so machines are found and assigned to protection without manual inventory — no blind spots.
Agentless, hypervisor-native backup uses native Microsoft Hyper-V APIs, with no agent footprint inside the guest OS for either backup or restore.
Agent-based ShadowProtect deployment provides:
OAuth 2.0 for SMTP: modern, secure authentication for email notifications, so SLA-breach alerts reliably get through.
Silent installation: Deploy at scale through RMM or GPO for zero-touch onboarding.
Predictable backup sizes: consistent backup size generation across successive runs eliminates unexpected storage growth.
Faster job management: search and filter backup jobs by name, status, or VM ID from the redesigned job page.
Providing both host-based and agent-based deployment options for ShadowProtect enables organizations to align data protection with diverse infrastructure requirements, operational models, and recovery objectives.
Having both options:
Reduces implementation constraints
Supports broader workload coverage
Allows IT teams to select the protection method that best balances performance, manageability, and recovery readiness across physical, virtual, and hybrid environments
Lower operational overhead: protect multiple VMs centrally through the Hyper-V host
Faster deployment: no guest-OS backup agents to install and maintain
Less disruptive to client operations: no host or VM reboots required during installation or upgrades
Consistent recovery options: VM-level, file-level, and disk-level restore from a single backup
Host-Based Backup (Hyper-V-Native, New in ShadowProtect 8.0)
Protects VMs through the Hyper-V host itself, no agent installed inside each guest OS
Applies backup policy centrally across many VMs from a single management interface
Best fit when: standardization and administrative efficiency matter most.
Agent-Based Backup (General-Purpose, Applies to Hyper-V VMs and Beyond)
Protects each individual server or VM, regardless of platform (Hyper-V is one of many environments it covers)
Gives OS-level visibility and per-VM policy control
Best fit when: workloads vary widely or need app-specific recovery handling.
Flexible, portable backup formats (SPF & SPI): whichever model you choose, backups are stored in proven ShadowProtect formats that integrate with existing workflows and MSPs already know how to work with these files
Direct VHDX restore to Microsoft Hyper-V: both host-based and agent-based backups support rapid virtual disk restore back to a Hyper-V host for full VM recovery or fast redeployment after an incident
Ransomware and other attack scenarios are a primary driver behind how MSPs structure Hyper-V backup architecture today.
Host-based backup adds a new, centralized recovery path at the Hyper-V host level; agent-based backup continues to deliver the same OS-level recovery it always has, for Hyper-V VMs and every other workload it protects.
Choosing the right model for your Hyper-V environment is a cyber resilience decision, not just a backup-configuration one.

MSP Prime ICT Defeats Christmas Eve Ransomware Attack With Arcserve Backup Solution When ransomware strikes during the holidays, cyber resilience makes the difference between business continuity and catastrophic loss. The Prime ICT Christmas Eve crisis demonstrates how the right data backup strategy protects against sophisticated attacks that can cost organizations hundreds of thousands of dollars. |
There’s no one-size-fits-all answer to host-based versus agent-based data protection. The best backup strategy depends on an MSP’s clients’ current Microsoft Hyper-V environments, operational requirements, and how much standardization the MSP wants to achieve across its customer base.
When evaluating backup architectures, MSPs should focus on manageability, scalability, recovery objectives, and long-term service efficiency. Use the following guidance to determine which approach aligns best with each customer’s environment:
Adopt host-based when you're managing many VMs across one or more Hyper-V hosts and want a single, centralized point of policy control. This approach minimizes the footprint inside each VM and simplifies day-to-day administration as your Hyper-V fleet grows
Continue with agent-based when individual workloads need OS-level visibility or app-aware recovery, the same general-purpose protection it has always provided, for Hyper-V VMs, physical servers, and everything else in your environment
Run both side by side where that fits your environment: host-based for standardized Hyper-V fleets where uniform policy matters most, agent-based wherever workload-specific control or app-level recovery is still the priority
Good to know host-based licensing is per Hyper-V host (not shared across hosts) and is supported on Windows Server 2016 and above.
Leverage agent-based backups with Arcserve ShadowProtect 8.0 to streamline backup administration through integrated backup chain management, consolidation, replication, and Advanced Verification, reducing manual oversight and operational workload.
Or host-based (agentless) backups, where ImageManager 8.1 automates backup chain management and replication, helping MSPs and IT teams manage more workloads with less day-to-day effort.
Note: At this time Advanced Verification is not currently supported for Arcserve ShadowProtect 8.0 host-based backups.
ImageManager 8.1 strengthens compliance readiness while reducing time spent on validation and audit preparation through automatic virtual boot testing, enhanced OS check disk tracking, a centralized verification dashboard, and exportable verification history reports.
New APIs help MSPs reduce reporting and integration effort by feeding verification data directly into existing dashboards, reporting platforms, and automation workflows, minimizing manual data collection and accelerating service delivery.
For MSPs supporting Microsoft Hyper-V environments, choosing the right backup model directly affects service efficiency, recovery readiness, and day-to-day workload. Watch the on-demand webinar to see how host-based and agent-based protection compare in Arcserve ShadowProtect 8.0, and how Arcserve ImageManager 8.1 helps streamline backup chain management, verification, and reporting.
