Below is the list of prerequisites and supported configurations for tape integration:

Veeam Backup & Replication allows working with tape devices directly attached to the Veeam Backup server (for example, connected over Fiber Channel (FC), Serial Attached SCSI (SAS), SCSI) or remote devices connected to Veeam Backup server via iSCSI (you can use Microsoft iSCSI initiator to establish the connection).

Device-specific, vendor-supplied OEM driver for Windows must be installed. Devices appearing in Windows Device Manager as Unknown or Generic are not supported.

If multiple driver installation modes are supported for your storage device, make sure the driver is installed in the mode that allows for multiple open handles from a host to a drive to exist at the same time. In particular, a vendor can support exclusive and non-exclusive driver types — if so, you should install the non-exclusive driver. For example, if installing a driver for IBM System Storage TS3100 Tape Library or TS3200 Tape Library, you should use the install_nonexclusive.exe installer as described in the product Readme.

LTO3 or later tape libraries (including VTL) and standalone drives are supported.

Consider that VMware does not support tape drives connected directly to ESXi 5.x.

noteNote

For more details and recommendations on configuring vendor-supported tape drives and media changers on ESX/ESXi, please refer to VMware documentation (http://kb.vmware.com/kb/1016407).

Starting with version 7.0 R2 (update to build 7.0.0.764 is required), Veeam Backup & Replication supports tape libraries with configured partitioning functionality that allows presenting multiple tape library partitions to the same host.

Veeam Backup & Replication supports file backup from any machine that has been added as a managed server to the Veeam Backup management console (that is, Windows or Linux server, including physical boxes). It is also possible to backup NAS devices by specifying the SMB path to the share.

If you plan to run both Veeam Backup & Replication and 3rd party tape-recording software (for example, in your evaluation lab), consider that Veeam by default will periodically lock the drive to perform rescan, preventing other software from recording.

If you want to modify the rescan interval, make sure that Veeam Backup & Replication has been updated with patch #1 (build 7.0.0.715) or with patch #2 (R2, build 7.0.0.764). Then do the following:

1.Open the registry editor

2.Drill down to HKEY_LOCAL_MACHINE\SOFTWARE\VeeaM\Veeam Backup and Replication

3.Look for this registry key (or create it anew): DWORD ChangerElementFillCompletionTimeoutSec

4.Set the DWORD value to the desired number (in decimal) — drive rescan timeout will be set to this interval in seconds. For example, 31536000 in decimal will prevent from rescanning for 1 year.

If you want to turn the rescan OFF, make sure that Veeam Backup & Replication has been updated with patch #2 (R2, build 7.0.0.764). Then do the following:

1.Open the registry editor

2.Drill down to HKEY_LOCAL_MACHINE\SOFTWARE\VeeaM\Veeam Backup and Replication

3.Look for this registry key: DWORD DisableTapeSubsystem

4.To turn OFF the rescan, set the value to 1. To turn ON the rescan, set it to 0 (use default rescan timeout 30 sec, or modify it as described above).
