Event Details

Both Cinder and Manila have always supported creating snapshots of volumes & file shares. But the only action users could take with snapshots was to create new volumes/shares from them. While a valuable use case, other scenarios demand alternate snapshot workflows.

We will explore and demonstrate three primary cloud snapshot semantics in Manila and the use cases they satisfy. We will also note progress in Cinder towards the same.

• Create share from snapshot. Useful for DevOps, testing, cloning from templates, and training.
• Revert share to snapshot. When widespread issues occur, such as filesystem corruption or malware infection, the best solution is to turn back the clock to before the problem occurred.
• Mount share snapshot. For quickly accessing and restoring previous versions of your files without any additional resource consumption.

We will cover the pros and cons of these approaches, as well as best practices to ensure data can be recovered in the most efficient way.
