We saw in the previous post How to backup volumes in BCOS? The process of creating and restoring volume backups, in this post we will look at the snapshot features.

 Snapshot is an image that preserves the state of a running machine, and thus can create another instance preserving the files and settings of the machine on which the snapshot was taken.

  Attention: The snapshot feature causes loss of access to the machine until termination, the machine is not restarted in the process.

  From the image, create a instance by repeating the second creation procedure, but on the Source tab select Instance Snapshot and keep the snap-vm02 option as the image:

 Having created the instance log in to your console and check the folders that were created on VM02:
