OpenStack has two different storage options: Volumes, which are protected by 3 times replication, and ephemeral storage local to the VM. The 3 times replication of Volumes is to protect against hardware failure and does not protect against accidental deletion or data loss from malicious intent. Data stored on node local ephemeral storage can suffer data lose due to hardware failure and should not be relied upon for any critical data and is best suited to temporary or working data. | |||
OpenStack provides tools to create disk images and snapshots of your virtual machines. The two main VM flavors - persistent (p) and compute (c) - have different behaviors and creating disk images or snapshots should be considered differently for each. | OpenStack provides tools to create disk images and snapshots of your virtual machines.
