Subject RE: KVM Incremental Backups & Live Storage Migration
Date Tue, 21 Mar 2017 16:50:43 GMT

Thank you for the info.  Forgive me, but I am still a bit new to the github/open source development
world.  So please allow me to ask for some clarifications:

- Has the PR for KVM Live Storage Migration been implemented into CloudStack or is that something
that is in development?

- The 4.10 release does have Incremental backup capabilities for KVM?

Thanks for the help!

Hi Jeromy,

Take a look at this PR regarding KVM live storage migration:

In terms of live snapshots, KVM live snaps (with memory) got merged fairly recently into the
4.10 future release. It backs up incremental snapshots to primary storage. Disk only snaps
have been supported for quite a long time.

Hello All,

Does anyone out there have a solution for doing incremental snapshots or backups of KVM (QCOW2)
VM images? Also, does anyone know of any movement for doing Live Storage Migration for KVM
VMs? In VMware you can "Storage vMotion" a VM's disks, but I have not seen anything to do
the same with KVM in CloudStack.

Any advice is appreciated.
