Volume Backup Functionality: Implementation and Testing Notes

Automated tests

We implemented a single testcase,

• scs-0117-test-backup,

which verifies that a non-admin user can backup and restore volumes.

To this end, the testcase uses the /v3/{project_id}/backups Block Storage API endpoint to create a volume and a backup of it and subsequently restores the backup on a new volume while verifying the success of each operation.

The testcase can be run using the script openstack_test.py.

Manual tests

Note that the automated tests don't verify the optional part of the standard: providing a separate storage backend for Cinder volume backups. This cannot be checked from outside of the infrastructure as it is an architectural property of the infrastructure itself and transparent to customers.
