Backup Strategy
===============
Backup strategy allows the user to customize the way of creating backups. Users
can create strategy either in the project scope or for a particular database
instance.
List backup strategies
~~~~~~~~~~~~~~~~~~~~~~
.. rest_method:: GET /v1.0/{project_id}/backup_strategies
List backup strategies for a project. You can filter the results by
using query string parameters. The following filters are supported:
- ``instance_id={instance_id}`` - Return the list of backup strategies for a
particular database instance.
- ``project_id={project_id}`` - Return the list of backup strategies for a
particular project, admin only.

=======================
Use incremental backups
=======================
Incremental backups let you chain together a series of backups. You
start with a regular backup. Then, when you want to create a subsequent
incremental backup, you specify the parent backup.
Restoring a database instance from an incremental backup is the same as
creating a database instance from a regular backup—the Database service
handles the complexities of applying the chain of incremental backups.
The artifacts created by backup are stored in OpenStack Swift, by default in a
container named 'database_backups'. As the end user, you are able to access all
the objects but make sure not to delete those objects manually. When a backup
is deleted in Trove, the related objects are automatically removed from Swift.
.. caution::
If the objects in 'database_backups' container are deleted manually, the
database can't be properly restored.
This example shows you how to use incremental backups with a MySQL
database.
**Assumptions.** Assume that you have created a regular
backup for the following database instance:
- Instance name: ``guest1``
- ID of the instance (``INSTANCE_ID``):
``792a6a56-278f-4a01-9997-d997fa126370``
- ID of the regular backup artifact (``BACKUP_ID``):
``6dc3a9b7-1f3e-4954-8582-3f2e4942cddd``
Create and use incremental backups
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#. **Create your first incremental backup**
Use the :command:`openstack database backup create` command and specify:
- The ``INSTANCE_ID`` of the database instance you are doing the
incremental backup for (in this example,
``792a6a56-278f-4a01-9997-d997fa126370``)
- The name of the incremental backup you are creating: ``backup1.1``
- The ``BACKUP_ID`` of the parent backup. In this case, the parent
is the regular backup, with an ID of
``6dc3a9b7-1f3e-4954-8582-3f2e4942cddd``
.. code-block:: console
$ openstack database backup create INSTANCE_ID backup1.1 --parent BACKUP_ID

| status | NEW |
| updated | 2014-03-19T14:09:13 |
+-------------+--------------------------------------+
Note that this command returns both the ID of the database instance
you are incrementally backing up (``instance_id``) and a new ID for
the new incremental backup artifact you just created (``id``).
#. **Create your second incremental backup**
The name of your second incremental backup is ``backup1.2``. This
time, when you specify the parent, pass in the ID of the incremental
backup you just created in the previous step (``backup1.1``). In this
example, it is ``1d474981-a006-4f62-b25f-43d7b8a7097e``.
.. code-block:: console
$ openstack database backup create INSTANCE_ID backup1.2 --parent BACKUP_ID

| size | None |
| status | NEW |
| updated | 2014-03-19T14:09:13 |
+-------------+--------------------------------------+
#. **Restore using incremental backups**
Now assume that your ``guest1`` database instance is damaged and you
need to restore it from your incremental backups. In this example,
you use the :command:`openstack database instance create` command to create a new database
instance called ``guest2``.
To incorporate your incremental backups, you simply use the
`--backup`` parameter to pass in the ``BACKUP_ID`` of your most
recent incremental backup. The Database service handles the
complexities of applying the chain of all previous incremental
backups.
.. code-block:: console
$ openstack database instance create guest2 10 --size 1 --nic net-id=$network_id --backup BACKUP_ID

The backup data is stored in OpenStack Swift, the user is able to customize
which container to store the data. The following ways are described in the
order of precedence from greatest to least:
1. The container name can be specified when creating backups, this could
override either the backup strategy setting or the default setting in Trove
configuration.
2. Users could create backup strategy either for the project scope or for a
particular instance.
3. If not configured by the end user, will use the default value in Trove
configuration.

#. **Before creating backup**
1. Make sure you have created an instance, e.g. in this example, we use the following instance:

2. Optionally, create a backup strategy for the instance. You can also specify a different swift container name (``--swift-container``) when creating the backup.
.. code-block:: console

#. **Backup the database instance**
As background, assume that you have created a database
instance with the following
characteristics:
- Name of the database instance: ``guest1``
- Flavor ID: ``10``
- Root volume size: ``2``
- Databases: ``db1`` and ``db2``
- Users: The ``user1`` user with the ``password`` password
First, get the ID of the ``guest1`` database instance by using the
:command:`openstack database instance list` command:
.. code-block:: console

+--------------------------------------+--------+-----------+-------------------+--------+-----------+------+
Back up the database instance by using the :command:`openstack database backup create`
command. In this example, the backup is called ``backup1``. In this
example, replace ``INSTANCE_ID`` with
``97b4b853-80f6-414f-ba6f-c6f455a79ae6``:
