Epic Goal*

Add support for snapshots in Azure File as GA.

Why is this important? (mandatory)

We should track upstream issues and ensure enablement in OpenShift. Snapshots are a standard feature of CSI and the reason we did not support it until now was lacking upstream support for snapshot restoration.

Snapshot restore feature was added recently in 4.17 as Tech Preview

However, we've observed a few issues with cloning and snapshots that need to be fixed before we can promote it GA. 

 
Scenarios (mandatory) 

Users should be able to create a snapshot and restore PVC from snapshots.

 
Dependencies (internal and external) (mandatory)

azcopy - already added in scope of cloning epic

upstream driver support for snapshot restore - already added in 4.17 as TP

Bug fixes to the known issues.

Contributing Teams(and contacts) (mandatory) 

Our expectation is that teams would modify the list below to fit the epic. Some epics may not need all the default groups but what is included here should accurately reflect who will be involved in delivering the epic.

• Development - STOR
• Documentation - STOR
• QE - 

Acceptance Criteria (optional)

Pass regular CSI / Snapshots CI & tests 

Drawbacks or Risk (optional)

Reasons we should consider NOT doing this such as: limited audience for the feature, feature will be superseded by other work that is planned, resulting feature will introduce substantial administrative complexity or user confusion, etc.

Done - Checklist (mandatory)

The following points apply to all epics and are what the OpenShift team believes are the minimum set of criteria that epics should meet for us to consider them potentially shippable. We request that epic owners modify this list to reflect the work to be completed in order to produce something that is potentially shippable.

• CI Testing -  Basic e2e automationTests are merged and completing successfully
• Documentation - Content development is complete.
• QE - Test scenarios are written and executed successfully.
• Technical Enablement - Slides are complete (if requested by PLM)
• Engineering Stories Merged
• All associated work items with the Epic are closed
• Epic status should be “Release Pending”
