Create a Colocated Volume Snapshot
Creating a snapshot of a storage volume enables you to capture all the data that is currently stored on the storage volume.
If the storage volume is attached to an instance, then only data that has already been written to the storage volume will be captured in the snapshot. Data that is cached by the application or the operating system will be excluded from the snapshot.
After creating a volume snapshot, you can use it to create a storage volume that’s identical to the original volume. See Restore a Volume from a Snapshot.
