Virtual TapeServer 6.04.05 for NonStop Servers Supplemental Installation Guide

Enabling and Configuring BMA Integration and

Migration

BMA integration enables a backup management application server to read and write files to

and from Virtual TapeServer (VTS). You can then enable VTS to export, or “migrate”, virtual

tapes to physical tapes using an attached external tape device. To configure VTS to

automatically migrate virtual tapes, you must

• Install a backup management application client on the VTS server

• Configure the Event Management Service (EMS) on VTS

• Configure the VTSPolicy command on the VTS server

You can also manually initiate migration by clicking the Migrate button on the Virtual Media

- Operation page. A backup management application client must be installed and configured

on the VTS server to enable manual migration. You can use an external tape device attached

during installation, or you can attach a device as described in

Attaching External Devices

after Initial Deployment on page 157.

Migration allows for better use of the disk space on the storage array. For instance, if a virtual

tape needs to be saved for seven years for legal purposes, it is not fiscally prudent to keep that

data on disk. You could automatically migrate the virtual tape to physical tape. In the

unlikely event that the virtual tape is needed, VTS can automatically request that the backup

management application server restore it from physical tape.

When a virtual tape is migrated to physical tape, all data on the virtual tape is written to

physical tape, including the header information (metadata). To restore a physical tape that

was automatically migrated by a backup management application, the backup management

application must restore the tape to VTS. Host servers cannot read physical tapes that were

created through migration because the tape is formatted for use by VTS only. After the data is

restored as a virtual tape in VTS, the host server can then restore the data.

Note You can export a virtual tape to physical tape using a native export job, which does

not require backup management application integration. See the Virtual TapeServer

Configuration Guide for more information.

The backup management application client must be installed on the VTS server, which is

based on the Linux operating system. The backup management application treats VTS as a

UNIX host on the enterprise network. Virtual tapes are then migrated to the tape library

managed by the backup management application server according to policies set by the

backup management application administrator. The backup management application server

can migrate virtual tapes using the following methods:

• The backup management application administrator creates a backup job on the backup

management application server and schedules it to run on the backup management

application client. The backup management application server manages the entire
