Hi Giuseppe, A general list of what has been implemented is available here:
- https://blueprints.launchpad.net/freezer/+specs?show=all (Delivery->Implemented) If you want to dive deep on the related source code, you can find all the merged commits here: - https://review.openstack.org/#/q/project:stackforge/freezer+status:merged,n,z We are in the process of splitting the GIT repos, but in the main freezer repo you can find the following README that can provide more information: - API: https://github.com/stackforge/freezer/blob/master/freezer_api/README.rst - Freezer-agent (former freezer client): https://github.com/stackforge/freezer/blob/master/README.rst - Some basic instruction on how to install the Horizon Web UI: https://github.com/stackforge/freezer/tree/master/horizon_web_ui - Job config file example: https://github.com/stackforge/freezer/blob/master/specs/job-backup.conf.example - Freezer public meetings notes: https://etherpad.openstack.org/p/freezer_meetings We are in the process of providing better documentation. It should happen by Fri 24th of July. That would include a complete list of supported features.

Hi Fausto, where can I find information about implemented and currently working functionalities? Thank you, Giuseppe 2015-07-07 13:28 GMT+02:00 Marzi, Fausto <fausto.ma...@hp.com<mailto:fausto.ma...@hp.com>>: Hi Giuseppe, Avishay, all, In the Company where I'm currently working on, there are 4 Engineers full time dedicated to Freezer. Your consideration Avishay make totally sense. There are also other points that probably needs to be taken in consideration for DR as: - Backup and restore synchronized across multiple services: This is important, as for instance Nova depends on many other OS service (i.e. cinder, glance, etc). - When users execute a backup of a VM, it is also expected that the Cinder Volumes, the images and the users/tenants can also be point-in-time restored - It is important to be able to restore data, even if any one of the OS Services is down (i.e. Keystone or Swift are not available). - The orchestration between Nova and Cinder to execute full VM + Cinder backups is important - Have a unified API and Web UI in Horizon is also a nice to have These and more are the challenges that in the Freezer Team we are solving. Being totally honest, Freezer has been used to backup many services in a reasonably big OpenStack instance for a year now. However, it's only 6 months there's a dedicated Team working on it, so many things still needs to be done. For any real time interaction, we are in #openstack-freezer on Freenode , so feel free to say Hi if you are around : ) Contributors are most welcome.

What can you tell me about the following projects: - https://wiki.openstack.org/wiki/Raksha - https://github.com/stackforge/freezer Will they become OpenStack project? Thanks, Giuseppe 2015-07-06 21:33 GMT+02:00 Avishay Traeger <avis...@stratoscale.com<mailto:avis...@stratoscale.com> <mailto:avis...@stratoscale.com<mailto:avis...@stratoscale.com>>>: As David mentioned, there is a spectrum of possible solutions for disaster recovery. The solution, as always, depends on the requirements. In disaster recovery, those requirements are expressed as: 1. RPO - Recovery Point Objective - "If a disaster strikes, how far back will it set me?" 2. RTO - Recovery Time Objective - "If a disaster strikes, how long until my workload is up and running?" The answers to both are independent and can range from "Not at all" to minutes or hours or days. A solution with high RPO and RTO is backup. Once in a while transfer your images, snapshots of your VMs and volumes, and your SQL DB to another site. If disaster strikes you can manually run your workloads from the last backup, and you have your metadata backed up too (keystone users/tenants, nova flavors, etc.). A solution with lower RPO and RTO is replication. Work is being done in Cinder to enable continuous volume replication between storage backends. You can put your Glance images in multiple locations or in multi-site Swift, and replicate your DB as well. Ideally you will be able to get to some consistent state between your data and metadata, which is not easy. For failover, you can use Heat or some other orchestration tool. There are solutions with zero RPO and RTO, where workloads run active/active in multiple sites. There are also other solutions in the spectrum. In short, the building blocks are starting to appear, but a full solution is not yet available.

Yes, Nova snaps (instance snaps) and Cinder snaps (volume snaps) can be used in DR. Additionally, depending on your architecture you can utilize Swift (if it is geo distributed, it gives you some measure of DR resilience.) I'm not aware of a howto or manual on this topic though as it varies so much based on arch and definition it's not effective to make a generalized recommendation.
