Veta is a backup manager for OpenStack, supporting fine-grained backup schedules and retention policies.

Veta supports both regular nova snapshots and Gridcentric VMS live-images as snapshot backends.

Veta must be installed on API nodes, Horizon nodes (if the Horizon plugin is desired) and on a controller node designated to run the Veta manager.

To install Veta, clone the repository and run:

sudo python setup.py install

You should add the Veta extension to your nova.conf in order to expose the API. You can do so by appending the following lines to nova.conf:

osapi_compute_extension=nova.api.openstack.compute.contrib.standard_extensions
osapi_compute_extension=veta.extension.Veta_extension

Next, you should restart the API server.

sudo restart nova-api

If you will be using Keystone authentication for Veta (e.g. if your Glance installation is using Keystone to authenticate requests), you will need to create a service account for Veta:

keystone user-create --name veta --tenant-id <SERVICE TENANT ID> --pass <VETA SERVICE PASSWORD>
keystone user-role-add --user-id <VETA USER ID> --tenant-id <SERVICE TENANT ID> --role-id <ADMIN ROLE ID>

(See the keystone tenant-list and keystone user-role-list commands for help on getting the appropriate <SERVICE TENANT ID> and <ADMIN ROLE ID> parameters.)

You will then need to add the following options to /etc/nova/veta-manager.conf, under the [DEFAULT] section:

[DEFAULT]
veta_auth_strategy=keystone
veta_auth_user=veta
veta_auth_tenant=<SERVICE TENANT NAME>
veta_auth_password=<VETA SERVICE PASSWORD>
veta_auth_url=<KEYSTONE URL> # Defaults to https://127.0.0.1:5000/v2.0

Veta comes with an upstart script for automatically starting on upstart-based systems. To start veta manually, use:

sudo start veta-manager

Note that the veta novaclient plugin must be installed on the Horizon node(s) in order for the Veta Horizon plugin to work.

To enable the Veta Horizon plugin, modify /etc/openstack-dashboard/local_settings.py (on Ubuntu Server 12.04) or /etc/openstack-dashboard/local_settings (on RHEL 6.4 / CentOS 6.4) and add the following lines:

import sys
mod = sys.modules['openstack_dashboard.settings']
mod.INSTALLED_APPS += ('veta.horizon',)

Then, restart the web server with service apache2 restart and navigate to Horizon. There will be a new panel labeled "Instance Backups".

To set the backup snapshot driver, you must add the option veta_snapshot_driver to a configuration file that is read by both nova-api and veta-manager, for example the /etc/nova/nova.conf file.

The following drivers are included with Veta:

• novadriver.NovaSnapshotDriver (default) - uses Nova "snapshots" (i.e. the output of nova image-create for instance backups.
• cobaltdriver.CobaltSnapshotDriver - uses Cobalt live images for instance backups.

For example, to use the Cobalt driver, append the following to /etc/nova/nova.conf:

veta_snapshot_driver=cobaltdriver.CobaltSnapshotDriver
