[Openstack] Scheduled Backup (was Openstack capabilities)

There is a need for an end user service for backup/snapshot on a schedule. Raksha (https://wiki.openstack.org/wiki/Raksha) was close but does not seem to be actively developed at the moment. Extensions for remote replication on schedule would be really welcome.

It is not clear to me how the standard user arranges a reasonable backup strategy for their VM currently on OpenStack ?

While there are some applications which can be re-created from scratch faster than from backup, the typical CERN test/dev instance is where people try out ideas before setting things up in Puppet or with external volumes. Explaining that the VM is lost is not an easy discussion.

It can all be scripted… can we arrange that this this requires a relatively limited effort to script ? Passwords, expiration of old images and replication are not trivial problems to solve for the average end user.

14.Supports backup manager

The snapshot operation and daily/weekly/hourly backup operations are currently supported via OpenStack Nova's API. However, if you're looking for some Windows GUI that does backups, that isn't something that OpenStack is about to provide.

      Yeah we do have API support for instance backup periodically , but AFAIK this feature doesn't work at all, there isn't a periodic worker doing that, and
       instance periodic backup info isn't stored anywhere, I have written a patch to implement that for a customer before, if this is a common feature request,  I'd like to discuss in the openstack-dev ML and contribute it to upstream.
