The diagram below illustrates the main components and processes within the backup infrastructure when tape support is implemented in Veeam Backup & Replication:
All connection types require driver installation
You can use generic drivers from Microsoft Windows, but they may not provide as high performance as the vendor’s
Separate drivers for tape drives and for tape media libraries should be installed
StorageTek ACSLS is not supported while a direct connection to the library is needed
Dynamic Drive Sharing is not supported
Library Partitioning is supported
Multiple control paths are supported only when control path failover and MPIO is configured correctly. Please contact the vendor for more information.
FC/SAS/SCSI/FCoE/Infiniband/iSCSI or other block technology to physical Tape Proxy are supported with Windows driver as long as the tape vendor supports the connection. (“Unknown media changer” support for FC/SAS and VTLs)
FC/SAS redirect to VMware VM is unsupported
FC/SAS redirect to Hyper-V VM is unsupported
FC/SAS to iSCSI Converter/Bridge is supported
Starwind Tape Redirector is supported
The Veeam Ready database provides a list of all partner solutions that have successfully passed Veeam’s testing criteria. Solutions are grouped by company name, Veeam Ready classification, and more. Veeam Ready Database
LTO-3 or higher
For VTLs, see the corresponding section under Deduplication Storage
IBM "Jaguar" TS11x0 Enterprise tape drives
StorageTek T10000 tape drives
Older Tape drives like DLT or AIT
IBM drivers: use “non-exclusive” driver setup and start installation with administrative rights.
HP drivers: these are not installable with the downloaded install .exe file on a VM (for example, to use with VTL). As a solution, run the install .exe and choose Extract. Use Device Manager –> Update driver and select the drivers for tape drives and (if you use HP/HP emulation tape library) for media changer.
Veeam supports medium changers that have no Microsoft Windows drivers available. Make sure that such device is recognized as an unknown medium changer in the Microsoft Device Manager list.
It is recommended that you use tape devices with original equipment manufacturer (OEM) drivers. Limitations VMware does not support tape drives connected directly to ESX(i) 4.x and later. For more information, see VMware vSphere Release Notes.
For more details and recommendations on configuring vendor-supported tape drives and media changers on ESX/ESXi, refer to VMware documentation at https://kb.vmware.com/s/article/1016407.
Note: Veeam Backup & Replication uses the MTF (Microsoft Tape Format) industry format to write data to tape. Veeam Backup & Replication also supports using WORM (Write Once Read Many) tapes.
