Virtual TapeServer 8.0 Configuration Guide

Enabling and Configuring Data Replication

Data Replication is a advanced software feature that enables you to back up data to remote

Virtual TapeServer (VTS) servers. This feature is implemented as

• Replicate jobs, for redundancy or disaster recovery purposes

• Remote export jobs, for high availability and role swapping purposes

Use replicate jobs to replicate data as part of your disaster recovery solution or to enable

multiple Virtual TapeServer servers to back up virtual tapes to a single remote server. The

VTS web interface enables you to view ownership of the virtual tapes that are replicated, and

the source server is the only server that can access those tapes. Replicated tapes are stored in

data partitions (/DATAxx) on the remote server.

This chapter describes how to enable and configure Virtual TapeServer for replicate jobs. See

Enabling and Configuring Role Swapping on page 45 for instructions to configure and use

remote export jobs.

Note Replicate jobs are available if a capacity license is enabled on the server.

Replicate jobs export virtual tapes (in VTDs within a VTL) to remote VTS servers. You must

define a source server where the job originates and one or more target servers, where the

replicated data is hosted. The source server ensures the virtual tape to be replicated contains

data. If the virtual tape was erased and has only a label (or no label), it cannot be replicated.

Each target server must be configured to accept replication requests from each of the defined

source servers. You must also configure the vaults that will be used on target servers to store

replication data.

You can also replicate data from one target server to another. If a target server is also

configured as a source server, it can then replicate the data to other servers:

At a glance, here is an overview of the steps to enable, configure, and use replicate jobs:

1. Configure data partitions on the remote (target) servers.

2. Enable Data Replication licensing using the VTS web interface as described in Enabling
