+# Staffeln
 
-OpenStack Boilerplate contains all the boilerplate you need to create an OpenStack package.
+## Project Description
 
-Please fill here a long description which must be at least 3 lines wrapped on
-80 cols, so that distribution package maintainers can use it in their packages.
-Note that this is a hard requirement.
+This solution is a volume-level scheduled backup to implement a non-intrusive automatic backup for Openstack VMs.  
 
-* Free software: Apache license
-* Documentation: https://docs.openstack.org/staffeln/latest
-* Source: https://opendev.org/openstack/staffeln
-* Bugs: https://bugs.launchpad.net/replace with the name of the project on Launchpad or the ID from Storyboard
+All volumes attached to the specified VMs are backed up periodically.
 
-Features
---------
+File-level backup will not be provided. The volume can be restored and attached to the target VM to restore any needed files. Users can restore through Horizon or the cli in self-service.
 
-* TODO
+## Functions
+
+### Function Overview
+
+The solution backs up all volumes attached to VMs which have a pre-defined metadata set, for
+example, `backup=yes`.
+First, it gets the list of VMs which have backup metadata and the list of volumes attached to the
+VMs in the given project by consuming the Openstack API (nova-api and cinder-api). Once the
+volume list is prepared, then it consumes cinder-backup API to perform the backup.
+Once the backup is successful, the backup time is updated in the metadata - `last-backup-time` of
+the VM.
+
+* *Filtering volumes:* It skips specific volumes if the volume metadata includes a specific
+`skip-volume-backup` flag.
+* *Limitation:* The number of volumes which users can backup is limited. Once the backup
+count exceeds the quota which is defined per project, the backup job would fail.
+* *Naming convention:* The backup volume name would be
+{VOLUME_NAME}-{BACKUP_DATE}.
+* Compression: all backup volumes are compressed at the ceph level. The compression
+mode, compression algorithm and required parameters are configured by the user.
+
+### Retention
+
+Based on the configured retention policy, the volumes are removed.
+Openstack API access policies are customized to make only the retention service be able to delete
+the backups and users not.
+
+### Scaling
+
+Cinder backup service is running on the dedicated backup host and it can be scaled across multiple
+backup hosts.
+
+### Notification
+
+Once the backup is finished, the results are notified to the specified users by email regardless of
+whether it was successful or not (the email will be one digest of all backups).
+Backup result HTML Template
+- Backup time
+- Current quota usage(Quota/used number/percentage) with proper colors
+  - 50% <= Quota usage : Green
+  - 80% > Quota > 50% usage : Yellow
+  - Quota usage > 80% : Red
+- Volume list
+- Success/fail: true/false with proper colors
+  - Fail: Red
+  - Success: Green
+- Fail reason
+
+### Settings
+
+Users can configure the settings to control the backup process. The parameters are;
+- Backup period
+- Volume filtering tag
+- Volume skip filter metadata tag
+- Volume limit number
+- Retention time
+- Archival rules
+- Compression mode, algorithm and parameters
+- Notification receiver list
+- Notification email HTML template
+- Openstack Credential
+
+### User Interface
+
+- Users can get the list of backup volumes on the Horizon cinder-backup panel. This panel
+has filtering and pagination functions which are not default ones of Horizon.
+- Users cannot delete the volumes on the UI. “Delete Volume Backup” button is disabled on
+the cinder-backup panel.
+
+## Dependencies
+
+* openstacksdk (API calls)
+* Flask (HTTP API)
+* oslo.service (long-running daemon)
+* pbr (using setup.cfg for build tooling)
+* oslo.db (database connections)
+* oslo.config (configuration files)
+
+
+## Architecture
+
+### HTTP API (staffeln-api)
+
+This project will need a basic HTTP API.  The primary reason for this is because when a user will attempt to delete a backup, we will use [oslo.policy via HTTP](https://docs.openstack.org/oslo.policy/victoria/user/plugins.html) to make sure that the backup they are attempting to delete is not an automated backup.
+
+This API will be unauthenticated and stateless, due to the fact that it is simply going to return the plain-text string True or fail with 401 Unauthorized.  Because of the simplicity of this API, [Flask](https://flask.palletsprojects.com/en/1.1.x/) is an excellent tool to be able to build it out.
+
+The flow of the HTTP call will look like the following:
+
+1. HTTP request received through oslo.policy when backup being deleted with ID
+2. Server look up backup ID using OpenStack API
+3. If backup metadata contains `__automated_backup=True` then deny, otherwise allow.
+
+With that flow, we’ll be able to protect automated backups from being deleted automatically.  In order to build a proper architecture, this application will be delivered as a WSGI application so it can be hosted via something like uWSGI later.
+
+### Daemon (staffeln-conductor)
+
+The conductor will be an independent daemon that will essentially scan all the virtual machines (grouped by project) which are marked to have automatic backups and then automatically start queueing up backups for them to be executed by Cinder.
+
+Once backups for a project are done, it should be able to start running the rotation policy that is configured on all the existing volumes and then send out a notification email afterwards to the user.
+
+The daemon should be stateful and ensure that it has its own state which is stored inside of a database.

-============================
-So You Want to Contribute...
-============================
-
-For general information on contributing to OpenStack, please check out the
-`contributor guide <https://docs.openstack.org/contributors/>`_ to get started.
-It covers all the basics that are common to all OpenStack projects: the accounts
-you need, the basics of interacting with our Gerrit review system, how we
-communicate as a community, etc.
-
-Below will cover the more project specific information you need to get started
-with replace with the service it implements.
-
-Communication
-~~~~~~~~~~~~~
-.. This would be a good place to put the channel you chat in as a project; when/
-   where your meeting is, the tags you prepend to your ML threads, etc.
-
-Contacting the Core Team
-~~~~~~~~~~~~~~~~~~~~~~~~
-.. This section should list the core team, their irc nicks, emails, timezones
-   etc. If all this info is maintained elsewhere (i.e. a wiki), you can link to
-   that instead of enumerating everyone here.
-
-New Feature Planning
-~~~~~~~~~~~~~~~~~~~~
-.. This section is for talking about the process to get a new feature in. Some
-   projects use blueprints, some want specs, some want both! Some projects
-   stick to a strict schedule when selecting what new features will be reviewed
-   for a release.
-
-Task Tracking
-~~~~~~~~~~~~~
-.. This section is about where you track tasks- launchpad? storyboard? is there
-   more than one launchpad project? what's the name of the project group in
-   storyboard?
-
-We track our tasks in Launchpad
-
-   https://bugs.launchpad.net/replace with the name of the project on Launchpad or the ID from Storyboard
-
-If you're looking for some smaller, easier work item to pick up and get started
-on, search for the 'low-hanging-fruit' tag.
-
-.. NOTE: If your tag is not 'low-hanging-fruit' please change the text above.
-
-Reporting a Bug
-~~~~~~~~~~~~~~~
-.. Pretty self explanatory section, link directly to where people should report
-   bugs for your project.
-
-You found an issue and want to make sure we are aware of it? You can do so on
-`Launchpad
-<https://bugs.launchpad.net/replace with the name of the project on Launchpad or the ID from Storyboard>`_.
-
-Getting Your Patch Merged
-~~~~~~~~~~~~~~~~~~~~~~~~~
-.. This section should have info about what it takes to get something merged. Do
-   you require one or two +2's before +W? Do some of your repos require unit
-   test changes with all patches? etc.
-
-Project Team Lead Duties
-~~~~~~~~~~~~~~~~~~~~~~~~
-.. this section is where you can put PTL specific duties not already listed in
-   the common PTL guide (linked below), or if you already have them written
-   up elsewhere you can link to that doc here.
-
-All common PTL duties are enumerated in the `PTL guide
-<https://docs.openstack.org/project-team-guide/ptl.html>`_.
