User-supplied raw-disk cost
Standard spinning repository
A spinning repository without appliance-class reduction has to scale close to the effective protected capacity. Enter that quote in the model below.
Storage Economics
Up to 92% lower backup storage cost.
Petabyte-scale effective backup capacity with fewer disks, fewer shelves and EBA included in the Sendense platform.
Veeam native data reduction can help, but large backup repositories often still force a choice: scale standard spinning disk or add a deduplicating appliance. Sendense EBA brings repository efficiency into the platform layer.
The savings compound as capacity grows: EBA adds commodity disk behind the same repository engine, while traditional designs keep expanding shelves or appliance spend.

Repository Designs
Same Capacity Target. Different Cost Inputs.
Compare three repository approaches against the same capacity target. Competitor quotes and hardware costs stay hidden until you enter them. Capacity and reduction equivalence must already be reflected in those quotes. Outputs are arithmetic from those inputs, not expected Sendense savings.

A deduplicating appliance can reduce disk footprint, but the appliance quote is still a design input. This page does not publish a competitor price.

User-supplied hardware cost
Sendense EBA design
EBA fingerprints, deduplicates and compresses VM data. Actual reduction depends on workload mix, change rate and retention. Enter a hardware-design cost to compare arithmetic.
Capacity Model
Three Repository Designs. One Capacity Target.
Compare a standard spinning repository, a deduplicating appliance design and a Sendense EBA repository design using the same 9:1 data reduction assumption.
The important trend is not just the starting number. Moving from 720 TB to 1.44 PB effective capacity adds about £3,300 to the Sendense EBA repository design, compared with about £49,900 for the raw spinning repository model and £85,000 in the dedupe appliance quote path.

Scale Comparison
Sendense EBA stays lean. External repository options get heavier.
This compares the incremental Sendense EBA hardware step with two non-Sendense repository choices: a raw spinning repository build and a quoted dedupe appliance path.

CSP Payback
Backup Storage Economics Built for CSP Margin.
For a provider selling protected capacity every month, lower repository capex changes the service margin. At £5 per TB per month, repository payback can be measured in weeks rather than years.
The larger the service becomes, the more important this gets: protected capacity revenue scales linearly, but the Sendense repository cost curve stays much flatter than raw disk or appliance-led designs.

Why Sendense EBA
Repository Efficiency Belongs in the Platform.
The value is not only the first purchase. Fewer disks also means less power, less cooling, less rack space, fewer disk failures and less time spent designing around a specialist appliance.
01
EBA Included
Deduplication, compression, retention and direct recovery behavior are part of the Sendense repository path.
02
NVMe Write Tier
A mirrored SSD tier absorbs hot write behavior while capacity sits on commodity spinning disk.
03
Lower Failure Surface
Fewer HDDs and shelves reduce the number of moving parts in the repository estate.
04
Service Margin
CSPs can sell protected capacity without repository capex consuming the service margin.
Assumptions
Assumptions Behind the Model.
The model stays empty until you enter assumptions so customer-specific quotes stay visible and are not presented as Sendense results.
01How does this compare with Veeam native data reduction?
Veeam includes native compression and data reduction features, but that is not the same repository model as Sendense EBA. For appliance-class repository economics, Veeam estates often have to choose between scaling standard raw disk or adding a deduplicating storage appliance.
02What dedupe and compression ratio is used?
The comparison uses a 9:1 effective data reduction assumption across all scenarios. Actual results depend on workload similarity, operating systems, change rate, retention depth, encryption scope and backup policy.
03What is included in the Sendense EBA cost examples?
The examples use Sendense repository design figures: 10 x 8 TB HDD with mirrored 3.2 TB NVMe tier at £6,300, and 20 x 8 TB HDD with the same NVMe tier at £9,600. EBA repository capability is included with Sendense.
04Why does the saving increase with scale?
EBA scales by adding commodity capacity behind the repository engine. Raw spinning repositories and dedupe appliances keep adding larger hardware blocks, so the cash, rack and power gap widens as protected capacity grows.
Based on UK storage quotes and commodity storage assumptions: 8 TB HDD at £360, 12-drive shelf at about £2,500, 9:1 data reduction, and the stated Sendense EBA repository designs. Figures exclude tax, support contracts, server chassis, RAID/spare overhead, power/cooling, finance costs and customer-specific implementation work.
