Just a post to link to a free software from StarWind, that allows to access from a virtual machine to a physical TapeReader:

 

Tape Redirector

Tape Redirector is free software that provides the interface for accessing a tape library via iSCSI protocol. This solution seamlessly integrates with any tape hardware and works with all backup solutions.

Key advantages

  • ZERO investments
  • Intuitive interface
  • Possibility to back up VM data directly to the tape hardware

StarWind Tape Redirector works with any tape hardware and tape backup software.

Direct Connection Between a VM and Tape Library via iSCSI

Challenge

Logical backup infrastructure cannot be preserved in virtualized environments when performing P2V migration. This happens because guest virtual machines don’t have direct access to the storage hardware, and in particular to tape drives and tape loaders. Consequently, backup software running in VMs cannot communicate with the tape hardware to perform backups.

Solution

Provide a VM with the interface for accessing the tape hardware. StarWind Tape Redirector acts as a translation layer between virtual machines and the tape library. As a result, VMs gain access to the tape drives and perform backups directly to the tape library.

Result

StarWind Tape Redirector makes it possible to preserve the existing logical backup infrastructure when performing P2V migration. Consequently, VMs have direct access to the tape library via iSCSI as if it had been locally attached, and interact with tape drives and loaders.
