You can create a copy of a Cloud Block Storage volume using two methods:
- Cloning Method (Volume-to-volume)
This is direct copy from your existing volume to a new blank volume on another storage node. Volume data is copied directly between CBS storage nodes over our high-speed local storage network. This method is recommended if you want to make quick copies of your volume data and use them immediately after creation.
- Snapshot Method (Volume-to-Snapshot-to-Volume)
This method requires the intermediate step of creating a volume snapshot. You first create snapshot from your existing volume, which gets stored in Cloud Files. Second, you create a new volume using your snapshot as the source. This process requires writing snapshot data in and out of Cloud Files so it can take longer than the Cloning Method. This method is recommended if you don’t require quick access to your copied volumes and want the added durability, and lower price, of having your volume snapshot stored in Cloud Files.
