7.15 How are Virtual Machines Backed Up?

Virtual machine backup is not handled directly by Oracle VM. However, there are a number of approaches to virtual machine backup that can take advantage of facilities already provided within Oracle VM. Most commonly virtual machine backup is achieved by performing cloning of a virtual machine. For the best possible result, this should be performed as a cold clone (i.e. where the virtual machine is stopped) as this ensures better data integrity. Cloning is discussed in more detail in Section 7.6, “How does Cloning Work?”.

It is equally possible to stop a virtual machine and then create a backup of the virtual machine files stored in the repository that is used for the server pool.

A more comprehensive discussion of virtual machine backup strategies is provided in Backing up Virtual Machines in the Oracle VM Administrator's Guide.
