StarWind Virtual Tape Library

StarWind Virtual Tape Library (VTL) assists businesses in eliminating their costly tape backup process while meeting regulatory data archival and retention requirements by using Virtual Tape Libraries hosted on-premise with cloud & object storage tiering. Protect critical backups from ransomware by storing them air-gapped on virtual tapes. Replicate and tier your backups to Azure, AWS, or any other public cloud to maximise the storage cost-efficiency and security. Finally, utilise any industry-standard object storage array for the ability to scale the local storage flexibly.



Archival and vaulting, another company’s pain, became faster and not that tedious and expensive thanks to StarWind Virtual Tape Library. Double Fine automated their media asset backups while keeping them within their grasp in B2 cloud storage. This approach turned out to be far more cost efficient than shipping LTO offsite.

SMB use case is targeted at organisations seeking to leverage cloud storage to automate their backup and archival processes. VTL automates and replaces any manual DR tape shipping and augments existing DR plans by offering both replication and tiering. Starwind can also assist with migrating the data to the cloud using hardware data migration tools like AWS Snowball or Blackblaze Fireball.

Enterprise use case is suited for organisations seeking to take advantage of both object based storage and cloud hosted storage to automate their backup, archival and media asset management. here, VTL provides cost-efficient, air-gapped, near-line storage for data assets that need to be kept locally on-premises. For backup and archive data, VTL automates and replaces manual DR tape shipping and improves current DR plans by offering replication and tiering to both object and cloud storage. StarWind can also assist with migrating the data to the cloud and using a data migration solution from your chosen cloud provider.

Service Provider use case allows Managed Service Providers to offer tape as a service (TaaS), repository as a service (RaaS), and backup as a service (BaaS) allowing MSPs to use cloud and object storage instead of physical LTO tapes. Service provider licensing offers a convenient annual per-user payment system. In addition, customer data migration services are provided free of charge.
