HP VAN SDN Controller Administrator Guide

6 Backup/Restore

Overview

This chapter describes controller backup and restore actions using cURL commands. For REST

APIs for enabling backup and restore, go to /systems in the RSdoc facility on the controller.

(Using a Google Chrome browser window on the controller, enter https://<

system_ip_address>:8443/api .) You cannot use RSdoc to download or upload files.

Note

Only one backup, restore, upload, or download operation can be active at any time

on a given controller or controller team. Parallel operations are not supported.

Back-Up a Controller

A controller backup takes a snapshot of the controller state, and includes the following in a

single file:

 Controller databases

 License compliance history and metrics log data

 In a teaming environment, the teaming configuration

 User repository folder (for user-installed applications)

 Controller configuration folder

Notes

Applications using Cassandra in a teamed mode cannot use the backup and restore

services in the HP VAN SDN Controller. In this case, off-the-shelf solutions are

recommended, such as rsync or Amanda.

Examples of cURL commands in this guide use the "--noproxy" option, which is

appropriate where execution of cURL commands do not need a proxy to access

controllers. If your network is set up such that a proxy is needed to access controllers,

use the "--proxy" option. For details on cURL proxy options, visit

http://curl.haxx.se/docs/manpage.html .

Backup Operation

A controller backup includes the controller configuration and databases in one *.zip file, and

creates a companion *.MD5 file containing the checksum for the backup. These two files

should be stored together in a safe location.

 Backups run in the background, and, except for locking the Cassandra database to

prevent writes, do not interrupt system operation.
