Virtual TapeServer 8.3 Configuration Guide

52 | Virtual TapeServer Configuration Guide
Steps to enable, configure, and use replicate jobs
1. Enable Data Replication licensing using the VTS web interface as described in Enabling
Licensed Features.
Note Multiple license keys are available for this feature, based on the desired transfer speed
(WAN Acceleration). If the licensed transfer speeds do not match on the source and
target systems, the lowest speed is used during replication.
2. Verify that the network servers (firewall, VPN, and so on) between the source and target
servers are configured to allow replication traffic; ports 22, 443, and 4567 are required.
3. Configure data partitions on the remote (target) servers as described in this chapter.
4. Configure source and target settings as described in this chapter..
5. If you want to send email notifications for completed or failed jobs, or after replicated tapes
are restored, configure SMTP settings as described in the help.
6. Replicate data to remote servers by creating and running replicate jobs as described in this
chapter.
Considerations
l If a virtual tape does not reside in a VTL, the replicate job will fail if the virtual tape is locked
at the time of the export.
l If an error occurs during replication, the replicate job is retried once every 30 seconds. The
retry is attempted up to 10 times.
l To recover data from a target server, you can restore virtual tapes using the Manage External
Data page of the web interface. You can then select the target server and list of virtual tapes
to restore. Refer to the help for more information.
Configure data partitions on target servers
To dedicate data partitions on a target server for use in replication, you can
l rename existing vault partitions, or
l add additional storage partitions to your server
To rename existing vault space
1. Remove or erase virtual tapes and pools in the file system chosen to be used as a data
partition. (Data currently residing in the vault partition will no longer be accessible to host
systems.)
2. Rename an existing partition. Note that you must move (rename) the vault mount point to the
new data mount point. Data file systems must be labeled DATAxx, where xx is a two-digit
number following the name. The file systems do not need to be numbered sequentially.
