Published: October 10, 2017

Value Proposition

For organizations looking to replace their legacy tape-centric backup infrastructure, we have designed StarWind Cloud VTL for AWS and Veeam. It delivers fast backup and replication to costefficient Amazon S3 and Glacier cloud storage and helps businesses leverage the benefits of AWS elasticity, scalability, and consumption model without having to rebuild their backup infrastructure policies from scratch. What is more, it creates ransomware-resilient virtual tape backups and ensures maximum level of data security by offloading additional copies to Amazon S3 and Glacier.

Furthermore, StarWind Cloud VTL offers “smart” data de-staging allowing to automatically offload backups from expensive local storage to cost-efficient cloud storage. It further enables to “tier” backups between cloud storage with different performance and efficiency features for maintaining low cost per GB without compromising RTO.

StarWind Cloud VTL for AWS and Veeam Overview

Backups are stored on local HDD repository. After that, they are offloaded to object storage in the cloud according to the specified retention policy.


The leading cost-effective object storage providers (i.e., Amazon S3 and Glacier, Azure Blob
Storage, Google Nearline, etc.) rarely provide a straightforward way to deploy and integrate their
inexpensive storage as a “cold” tier into existing infrastructures. StarWind Cloud VTL, in its turn,
allows easily integrating cloud storage tier into the existing backup infrastructure, without the
need to change established data vaulting policies.

Unlike other solutions that require to manually offload backups to a cloud storage, StarWind Cloud VTL makes the whole process automated. It allows configuring retention policies to store backups on local storage for a certain period and then automatically send them to cloud storage when it is needed.

Furthermore, StarWind virtual tapes are naturally ransomware-resilient since the virtual tape format is seen by ransomware as a physical tape which it can’t access by design. Also, StarWind Cloud VTL delivers an additional level of protection by offloading backups to Amazon S3 and Glacier cloud storage.


D2D2C Backup Strategy

StarWind Cloud VTL allows implementing Disk-to-Disk-to-Cloud (D2D2C) backup strategy. Being a variation D2D2T approach, it replaces local tape drives with inexpensive “tape in cloud” storage, delivering higher flexibility and cost-efficiency.

Ransomware Protection

StarWind Cloud VTL creates virtual tapes that are ransomware-resilient by default since ransomware simply can’t talk tape. Furthermore, additional copies in Amazon S3 and Glacier deliver maximum data security even if the entire local site is compromised.

Smart Backups De-Staging

StarWind Cloud VTL provides the ability to “tier” backups between cloud storage with different performance and efficiency characteristics for maintaining low cost per GB without compromising RTO.

Veeam Ready Solution

StarWind Cloud VTL is a Veeam Ready solution. Each software component has been pre-tested and checked for compatibility. It just works!


Fault Tolerance and High Availability

StarWind Cloud VTL is a backup storage solution, thus, it does not require continuous data availability. It utilizes redundancy and keeps an extra copy of backup data. Regarding this fact, there remains a copy that survives. Furthermore, there are replicas in S3 or Glacier which, in their turn, serve as an additional DR.


The retention policies can be configured to automatically offload older backups to the inexpensive cloud storage for “cold” data like Amazon Glacier, whilst keeping recent ones on both local storage and in Amazon S3. This approach ensures greater reliability and costefficiency for your data.

Cloud Virtual Tape Library

The solution is seamlessly integrated into the existing backup infrastructure without the need to rebuild the established data archival processes. Furthermore, D2D2C backup strategy allows replacing the costly local storage with a cost-efficient Amazon S3 and Glacier cloud storage.

Hardware-Agnostic and Commodity-Hardware-Based

StarWind Cloud VTL utilizes commodity servers and faster (but less expensive) high-capacity hard disks to emulate the tape hardware. The solution reduces costs for backups and accelerates backup jobs so that they do not overlap with production.


The offering is compatible with any existing virtualization environment. It is easy to deploy StarWind Cloud VTL in a hyperconverged infrastructure.


Even though hyperconvergence becomes increasingly prevalent, converged scenarios still are relevant. Regarding this fact, StarWind Cloud VTL easily integrates into any virtualization infrastructure.

VM-Centric Storage and StarWind Log-Structured File System (LSFS)

StarWind Cloud VTL utilizes LSFS to make backup jobs faster. It makes HDD more efficient because small random writes are aggregated in sequential parts. This strategy enables to avoid common virtualization-associated issues.

Server-Side Caching

StarWind Cloud VTL accelerates backup jobs by using multi-tiered flash and RAM caches. In addition, the conventional RAM, SATA, SSD, and MLC flash allow having bigger cache capacity for the same money.

Snapshots and Automated Storage Tiering

StarWind Cloud VTL works directly with snapshots employing the D2D2C backup strategy. The approach provides exceptional flexibility and cost-efficiency by replacing the local tape drives with cloud storage.

Deduplication and Compression

StarWind Cloud VTL uses data deduplication to reduce space consumption and conserve disk capacity. It also supports Microsoft Windows deduplication engine, together with StarWind Virtual SAN own space-reduction technologies. In addition to providing capacity savings, these technologies accelerate the performance since there is less data to transfer.
