Cloud Block Storage Volume Cloning Now In Control Panel

Starting today you can create copies of existing Cloud Block Storage volumes from the Control Panel with Volume Cloning.

You’re probably familiar with creating volumes from scratch, or creating volumes from snapshots, you can think of Volume Cloning as creating volumes from volumes.

Prior to Volume Cloning, if you wanted to make a copy of your CBS volume, you had to first snapshot your volume and then use the snapshot to create a new volume. While this process worked fine for most customers, it proved to be challenging for our customers who wanted quick access to the new volume. The main challenge was the amount of time it took to write the volume data in and out of Cloud Files during the snapshot and volume creation process.

With Volume Cloning, copies are now done directly between storage nodes, so the process is much quicker. Using the old snapshot method, creating a snapshot and then spinning up a new volume from that snapshot could take up to 45 minutes for a full 100 GB volume. With Volume Cloning, we’ve cut that down to about four minutes for that same 100 GB volume. Once the clone has completed, your volume is ready to be attached to your server and put to use.

Here’s what that process looks like:

From your Block Storage Volumes list, select the Action cogwheel next to the volume you wish to clone and choose Clone Volume.

When presented with the Volume Cloning popup, enter the volume name, volume type and size of the cloned volume. These can all be different than the original source volume. Now, select the Clone Volume button.

Depending on the size of the original volume, the cloning process can take several minutes. Once it has completed, you will have a usable copy of your original volume that can be attached to your server and is immediately ready for use.
