Enabling and Configuring Role Swapping
To enable “role swapping” of primary and secondary Virtual TapeServer (VTS) servers in your
environment, or to ensure high availability of data across sites, you can license and use the
Data Replication feature. Data Replication enables you to back up data to remote VTS
servers. This feature is implemented as
• Remote export jobs, for high availability and role swapping purposes
• Replicate jobs, for redundancy or disaster recovery purposes
Remote export jobs enable you to mirror data on a remote server. Virtual tapes that are
exported this way are stored in vaults (/VAULTxx) on the remote server. This chapter
describes how to enable and configure Virtual TapeServer for remote export jobs. See
Enabling and Configuring Data Replication on page 39 for instructions to configure and use
replicate jobs.
Note Remote export jobs are available if a capacity license is enabled on the server.
You may need to configure your environment for role swapping if you are
• Performing maintenance on a primary VTS server or site
• Implementing a disaster recovery (DR) plan or testing recovery procedures as part of
disaster-recovery preparedness
You can configure a primary VTS server to transfer data to a secondary (remote) server on a
regular basis. VTS copies data to the remote server over a wide area network (WAN) TCP/IP
connection.
Then, after swapping roles, the secondary site becomes the production site. After some period
of time, if desired, you can re-establish the primary site as the production site.
Before configuring remote export jobs, be aware of the following:
• VTS does not determine if virtual tapes are synchronized across servers. There is no way
to inform the administrator of either system that virtual tapes are synchronized or which
system last modified a virtual tape.
