Subject Re: [Propose][New Feature] Storage Snapshots
Date Thu, 04 Feb 2016 18:43:29 GMT
So if I understand correctly, currently taking a Volume Snapshots of a
volume on a managed storage keeps it on the storage array. As a part of
this feature, we can make sure that Volume Snapshots on managed storage are
uploaded to the secondary storage. This would make the Volume Snapshot
feature behave the same regardless of the storage (managed or non-managed)
And, for utilizing the efficient backend storage capabilities, we can use
the new storage snapshots API.
