Re: [Users] Hot Snapshotting of virtual disks
Hi Shu, Sorry I didn't go into more detail, yes I intend to copy the snapshot to a different medium (potentially to a DR site, at the very least to an independent NAS). The snapshot is just so I can grab a consistent copy of the disk (even though I understand it risks filesystem corruption due to incomplete writes) If oVirt now supports hot snapshots it in 3.1 we will look into this.

The first idea that came to mind was a hot snapshot of the virtual disk, however from what I can see ovirt won't allow that. Most of the others have serious drawbacks, so I wanted to know if anyone had a silver bullet before I put more time into it.
