+1 with this feature. like Logan said the current snapshot is just a copy of VDI/vmdk/qcow2's to the secondary storage hence the current feature acts as a backup feature taking a long time.
also the current cloudstack storage framework is not allowing the third party storage vendors like cloudbyte and others to leverage their backend storage snapshot feature where file systems support Copy on Write. for example : In cloudbyte elastistor which is based on zfs filesystem, it allows to take multiple snapshots within seconds. and a volume clones can be created from each snapshot. hence if the VDI/vmdk/qcow2's are already residing in the volume, the clones will just replicate the existing virtual disks. hence there will be no overhead of copying a snapshot to a new volume or primary storage over the network. hence there should be an option provided to leverage a snapshot and creating a volume out of it to the corresponding backend storage provider in use. thanks On Tue, Feb 17, 2015 at 3:11 AM, Mike Tutkowski < mike.tutkow...@solidfire.com> wrote: > Whatever way you think makes the most sense. > > Either way, I'm working on this for XenServer and ESXi (eventually on KVM, > I expect) for managed storage (SolidFire is an example of managed storage). > > On Mon, Feb 16, 2015 at 2:38 PM, Andrei Mikhailovsky <and...@arhont.com> > wrote: > > > I am happy to see the discussion is taking its pace and a lot of people > > tend to agree that we should address this area.
