What is a snapshot?
A snapshot captures the state of a volume or instance disk at a point in time. Snapshots can be:
- Used to restore a volume to a known-good state.
- Cloned into new volumes for testing or staging environments.
- Retained on a schedule as part of your backup policy.
Creating a snapshot
- Navigate to the instance or volume you wish to snapshot.
- Click Create snapshot.
- Provide a descriptive name and optional tags such as
env=prodorbefore-upgrade.
Restoring from a snapshot
Restoration typically involves cloning the snapshot to a new volume and attaching it to an instance:
- From the snapshot detail page, choose Create volume from snapshot.
- Attach the new volume to a test instance to validate data integrity.
- Once verified, attach to your production instance and update mount points.
