Sounds exciting! We've also been experimenting with Ceph volume/image mirroring (rbd mirror) lately, with the goal of potentially using it for multi-region DR and inter-region VM migration.
In an ideal world, we'd like migrate Ceph to a managed storage driver before we embark on adding mirroring support, but obviously implementation time frames will depend on commercial pressure. Backup via a third party tool could potentially ease the prem to cloud migration challenges, so any features that can be leveraged there are only good thing. - Si Simon Weller/615-312-6068 -----Original Message----- From: Paul Angus [paul.an...@shapeblue.com] Received: Thursday, 08 Feb 2018, 12:49PM To: users@cloudstack.apache.org [users@cloudstack.apache.org] Subject: RE: Customer Backup with CS 4.7 and VMWare Hi All, particularly Daniel, Sebastian and Simon, We, as a community are very much aware of the shortfalls in 'backup and recovery' options available natively in CloudStack - which is basically 'do volume snapshots'. Quite a while back, I published a high-level proposal of what I thought that a backup and recovery https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=70258527 I've continued to work on it, and am current speaking to a couple of backup vendors in order to have a framework concept that they will work with. Hopefully within a few weeks I'll be able to publish a substantive proposal for everyone to see and comment on.

Currently, most of our (internal) customers hosting internal services within this environment are using volume snapshots to facilitate backups of their virtual machines. Besides the obvious downsides of this approach (consistent snapshots of multiple volumes, …) we encounter serious problems using this features. In ~10% of the cases, snapshots get stuck in the BackingUp state, which sometimes causes the whole snapshot queue to stale. In some other cases, recurring snapshots are correctly configured, but CS does not try even try to create this snapshot, there is no entry in the database. In summary, we are currently evaluating different options, hence my questions here: * Are we the only ones encountering that massive problems with volume snapshots? Or is this a known problem? Anything we could look at or a hint where we could start troubleshooting? * How are you actually providing backup services to the customer? Are there other solutions or products that integrate with CS? When using another option than the volume snapshots in CS, the most important factor would be to keep the ability for the customer to configure everything in self-service. Thanks and regards Daniel
