Re: KVM Live Snapshots
Hi Asai, To answer your previous question - VM snapshots are inline in the qcow2 image, i.e. contained in the disk itself, and you need to use qemu-img convert to write this to a separate file.

Re: KVM Live Snapshots
This sounds like a great idea, except where can I find the VM snapshot in the file system? I’ve checked the database for some kind of indication, and I’ve check primary and secondary storage to try to locate this snapshot file but I can’t find it… Any insights on this? Thanks!

Re: KVM Live Snapshots
There are lots of ways you can implement a Business Continuity or DR plan. Some folks implement a second region or zone in a different market and build their applications or services to be resilient across different data centers (and/or markets). This often involved various forms of data replication (DB, file et al). If you rely on secondary storage for backups, the assumption here is that it uses a different storage system than your primary storage and it can be used for recovery if your primary storage was to fail. Now since the VM snapshot feature can be called by API and the resulting QCOW2 file is written to primary storage, you could use a script to execute the snapshot and then copy off the QCOW2 files somewhere else. You could also use something like the Veeam agent - https://www.veeam.com/windows-linux-availability-agents.html and backup your VMs to an offsite NFS mount. - Si From: Asai Sent: Thursday, August 23, 2018 4:06 PM To: users@cloudstack.apache.org Subject: Re: KVM Live Snapshots So, I think this is kind of an elephant in the room.

Re: KVM Live Snapshots
There is no way to run scheduled snapshots for whole vm, at least with KVM.

Great, thanks for that. So, is there a way then to make these whole VM snapshots recurring like recurring volume snapshots? What are best practices for recovering a volume snapshot? e.g. disaster recovery scenario? Asai

KVM whole VM snapshots work well in 4.11 as well as for separate volume snapshots. You can do both for NFS and local storages.

Re: KVM Live Snapshots
Simon - thanks for the reminder re VM snapshots - I think you've actually told me in the past as well. Asai - a VM snapshot remains on primary storage and is there for the purpose of rolling a VM back to a previous timestamp, and it is not available for download. Volume snapshots are copied to secondary storage for the purpose of downloading by end user - but these are handled on a per volume basis.

One of the main reasons we did this was that we thought this would enable us to do live KVM snapshots of running VMs. This doesn’t seem to be the case, though. When I try to snapshot a running VM, I just get the message: "KVM VM does not allow to take a disk-only snapshot when VM is in running state" Is there a way currently to do this with Cloudstack and KVM VMs?
