About Virtual Tape Library

Virtual Tape Libraries (VTLs) emulate tape libraries on disk. VTLs are included in NetVault as a licensable option.

With VTLs, you have the flexibility to perform quick backups to disks, and during off-peak hours migrate or duplicate the backups to physical devices for off-site storage. The Media Manager does not distinguish between virtual and physical tapes. Therefore, you can use the same process to set up backup policies, including retirement period and rotation schemes.

VTLs are represented as directories on the disk. Each VTL contains three directories: drives, slots, and media. These directories contain numbered subdirectories. The virtual drives reside as files in the drives subdirectories. These files contain links to the media files. The virtual tapes reside as media files in the media directory. When a virtual tape is moved between slot and drive, the media file itself stays in the media directory, while the drives and slots files are modified to emulate the moving of the media.

A VTL can handle any number of concurrent NetVault Client backups. As with a physical library, the number of drives contained in the VTL dictate how many simultaneous operations can be performed. The number of slots should be the same as or more than the number of configured drives. Different operating systems may impose maximum file-size limits, which can affect the maximum VTL media size.

Direct-to-cloud support

Beginning with release 12.3, NetVault supports StarWind Virtual Tape Library (StarWind VTL), which converts physical drives into virtual tapes to emulate tape hardware. It supports standard uplink protocols, including SMB3, NFSv4.1, iSCSI, and works with most virtual environments.

StarWind VTL is available on Microsoft Azure Marketplace, on AWS Marketplace, and as on-premises appliance

NetVault supports public and private cloud object storage replication with StarWind VTL through any of the following storage service providers:
