Request for Proposal: Snapshot Support

[afritzler]

As of now, the project does not support snapshots, a valuable feature that facilitates tasks such as data backup, environment duplication, and disaster recovery. Snapshot support could potentially allow users to create and manage point-in-time snapshots of their workloads seamlessly.

The proposal should address how we could integrate snapshot support, ideally including the following points:

• An overview of the envisioned integration
• High-level implementation details
• Sample specifications for Kubernetes (k8s) API resources
• Any potential challenges or roadblocks that may arise during implementation

Potential Next Steps

1. Understand the current state: Analyze the current onmetal-api structure to understand the best way to integrate snapshot support.
2. Research: Look into similar implementations to get ideas and understand potential pitfalls.
3. Draft Proposal: Begin drafting a proposal detailing how snapshot support could be integrated.
4. Review: Have the proposal reviewed by team members and stakeholders.
5. Iterate: Revise the proposal based on the feedback received.
