CloudStack Backup for KVM, QCOW2, NFS, ZFS and Linstor.
Backup for real CloudStack estates: mixed storage, tenant boundaries, non-NFS layouts and provider-scale recovery workflows.
Sendense helps CSPs and MSPs protect CloudStack KVM workloads across QCOW2/NFS, ZFS, Linstor/DRBD and mixed storage environments, with SNAgent coverage where host-side integration is required and EBA efficiency in the repository path.

CloudStack Backup Has To Match The Storage You Actually Run.
Service providers rarely have one neat storage backend. Sendense is built around the mix: KVM hosts, QCOW2/NFS, ZFS, Linstor/DRBD and storage paths that need host-side context.
Hypervisor Layer
CloudStack KVM Backup
Protect CloudStack KVM workloads through a model that understands host placement, storage paths and tenant boundaries instead of treating every VM as an isolated file copy.
Common CloudStack Storage
QCOW2 and NFS Backup
Back up QCOW2/NFS environments through an agentless, CBT-enabled path with consistent multi-disk capture, fast incrementals and EBA repository efficiency.
Snapshot-Aware Path
ZFS Backup
Protect ZFS-backed CloudStack zones without a Universal Client, using an agentless changed-block path designed for fast backup windows.
Distributed Block Storage
Linstor and DRBD Backup
Support CloudStack estates using Linstor/DRBD through an agentless CBT-enabled path, without forcing providers into a separate backup architecture for that storage class.
Workload Coverage
Agentless For Linstor, ZFS And QCOW2/NFS. Universal Client For Other Block.
Linstor/DRBD, ZFS and QCOW2/NFS are agentless, CBT-enabled and fast. For other block storage solutions, the Universal Client provides Windows changed-block tracking while EBA keeps retained capacity efficient.
Agentless CBT Paths
No Universal Client For Linstor, ZFS Or QCOW2/NFS
For CloudStack VMs on Linstor/DRBD, ZFS and QCOW2/NFS, Sendense uses agentless, CBT-enabled backup paths. That keeps protection fast without installing an in-guest client.
Windows Incrementals
Universal Client For Other Block Storage
For other CloudStack block storage solutions, the Sendense Universal Client provides Windows guest-side changed-block tracking while CloudStack snapshot coordination keeps data transfer efficient.
EBA Dedupe Safety Net
Linux Still Remains Capacity Efficient
Where a Linux workload is protected through a non-native full-read path, EBA deduplication means each run does not store another full copy; only new unique data consumes repository capacity.
Provider-Ready Coverage
Built For Mixed Storage, Not Just The Easy Case.
CloudStack backup needs to survive real estate design: mixed storage, non-NFS layouts, high tenant density and recurring service packaging.
Native Paths First, Universal Client When Needed
Linstor/DRBD, ZFS and QCOW2/NFS use agentless CBT-enabled backup. Other block storage can be covered with the Universal Client where Windows guest-side change tracking is needed.
EBA Keeps Provider Storage Cost Under Control
CloudStack backup data lands in the Sendense repository path, where EBA deduplication, compression, retention and restore behavior protect service margin.
Backup, Recovery and DR Stay in One Workflow
The same platform model supports backup, restore, recovery evidence, migration and CloudStack-based DRaaS rather than splitting each outcome into a separate tool.
Technical Landscape
CloudStack Backup Options Exist. The Coverage Gap Is The Problem.
Apache CloudStack includes backup and recovery framework concepts, but provider estates still need a practical answer for mixed storage, non-NFS paths, tenant operations and service-provider economics.
CloudStack B&R framework
Apache CloudStack documents a plugin-style backup and recovery framework, with provider-specific integrations rather than one universal storage answer.
Apache CloudStack B&R docsNamed provider paths
The CloudStack documentation references Veeam for VMware, Dell NetWorker for KVM and NAS B&R plugin support in the framework.
Apache CloudStack B&R docsNAS plugin reality
NAS-based backup can be useful, but many provider estates also need non-NFS coverage, tenant operations, repository economics and service packaging.
Apache CloudStack NAS plugin docsCSP and MSP Backup
Turn CloudStack Protection Into A Service, Not A Storage Project.
A CloudStack backup platform has to work commercially as well as technically: service tiers, customer reporting, repository margin and DR paths all matter.
Tenant-Aware Service Delivery
Package CloudStack backup around customers, tenants, zones and service tiers instead of exposing every storage detail to the buyer.
BaaS and DRaaS Margin
Pair CloudStack protection with EBA efficiency and provider-owned infrastructure so storage growth does not swallow the managed service.
Evidence for Service Reviews
Use job state, recovery points and validation evidence to show customers what is protected and what can be recovered.
Open Recovery Strategy
Use CloudStack as a backup source, recovery target or managed cloud platform without locking the whole service model to one hypervisor vendor.
The CloudStack Requirements Are Specific, But Not Heavy.
Sendense commissioning focuses on clear CloudStack prerequisites: API access, role permissions, SNAgent reachability, controller template readiness and the CloudStack objects needed for restore and replication workflows.

06CloudStack Backup FAQs
Short Answers For CloudStack Backup Buyers.
Practical answers for CloudStack operators, CSPs and MSPs evaluating backup across real KVM storage estates.
01What is the best way to back up CloudStack KVM workloads?
The best design depends on the CloudStack storage backend. Sendense is built for CloudStack KVM estates where backup needs to account for host placement, storage path, tenant boundaries and repository efficiency rather than relying on a single NAS-only model.
02Does Sendense support CloudStack QCOW2 and NFS backup?
Yes. QCOW2/NFS is an agentless, CBT-enabled Sendense path. No Universal Client is required for this storage class.
03Can Sendense protect non-NFS CloudStack storage?
Yes. Linstor/DRBD and ZFS use agentless CBT-enabled paths. For other CloudStack block storage solutions, Sendense uses the Universal Client where Windows guest-side change tracking is needed.
04Can Sendense back up any CloudStack storage backend?
Yes. Linstor/DRBD, ZFS and QCOW2/NFS are agentless and CBT-enabled. Other CloudStack block storage backends can be covered with the Universal Client, with EBA dedupe keeping retained storage efficient.
05Are CloudStack Windows backups incremental?
Yes. On Linstor/DRBD, ZFS and QCOW2/NFS, Windows VMs are protected through the same agentless CBT-enabled paths as other workloads. On other block storage, the Universal Client provides Windows in-guest changed-block tracking.
06What about Linux CloudStack VMs?
Linux VMs on Linstor/DRBD, ZFS and QCOW2/NFS use agentless CBT-enabled backup. Where a Linux workload is protected through a non-native full-read path, EBA dedupe prevents repeated runs from retaining another full copy.
07Is Sendense suitable for CloudStack service providers?
Yes. Sendense is designed for CSP and MSP use cases, including tenant-aware operations, BaaS, DRaaS, EBA repository efficiency and CloudStack recovery workflows.
08How does EBA help CloudStack backup economics?
EBA is included with Sendense and provides deduplication, compression, retention controls and efficient restore behavior, helping providers reduce repository storage cost while preserving service margin.
