Once you have created a volume, you can increase its size using the API by either of two methods:
- Cloning from a source volume to a new larger volume, or
- Creating a new larger volume from an existing volume snapshot.
Alternatively, in order to move to a larger or smaller volume size, you might need create a new volume of the desired size and then copy your data from the original volume to the new volume. Please note that you will be required to resize your file system when moving to a smaller volume (if supported by your operating system).
When you copy your data within the same data center via the internal ServiceNet network, there is no charge for bandwidth.
