Virtual TapeServer 6.03.42 Installation Guide

90 | Enabling Enterprise Integration and Migration
The BMA client must be installed on the VTS server, which is based on the Linux operating
system. The BMA treats VTS as a UNIX host on the enterprise network. Virtual tapes are
then migrated to the tape library managed by the BMA server according to policies set by the
BMA administrator. The BMA server can migrate virtual tapes using the following methods:
• The BMA administrator creates a backup job on the BMA server and schedules it to run
on the BMA client. The BMA server manages the entire process and maintains a database
of the backup files including a list of physical tapes to which the data was written. The
BMA server also controls the tape library.
If VTS deletes or erases a virtual tape, the BMA administrator must restore the virtual
tape, when necessary. If the server requests access to a virtual tape that was erased or
deleted, the mount request is queued on VTS until the data is recovered by the BMA
server from physical tape.
• VTS can request that the BMA server perform a backup or restore. This request is
generated when you manually initiate a migration. This request is issued using the BMA
command-line interface. VTS generates the BMA command request and sends it directly
to the BMA server. The BMA server then identifies the tape to back up or restore and
instructs the tape library to perform the operation.
• A VTSPolicy command sent from the host server through EMS can initiate migration.
VTSPolicy can initiate many of the commands that are available on the BMA server. The
command can be scheduled on the host server using NetBatch or appended to a Tandem
Advanced Command Language (TACL) backup script.
This chapter describes how to configure VTS for enterprise integration and migration. It also
includes information about adding a physical tape drive, which may be necessary for
migration. Refer to the Virtual TapeServer Operations and Administration Guide for
instructions to manually initiate migrating virtual tapes, encrypt data during migration, and
automate migration using the VTSPolicy command.
