16. the domain for the Oracle VM Manager application is ovm_domain 5 3 Backing up Virtual Machines some of them and the pros and cons for each One of the main points that should be considered when backing up a virtual machine is whether you can shut down the virtual machine during the back up Backing up a running virtual machine allows the machine to be available for use but does not allow for a back up that is consistent or easy to restore Creating a back up of a running virtual machine is similar to taking a back up of a running database without putting the tablespaces in back up or read only mode The first couple of blocks you back up from a the virtual machine are likely to be out of sync with the last blocks of your back up If and when you try to restore a back up taken from a running virtual machine you may not be able to rebuild the machine due to disk errors You can install back up software in the virtual machine for example Oracle Secure Backup This allows you to safely back up a running virtual machine The ease by which you can restore the virtual machine from the back up depends on the software used The following table discusses some virtual machine back up options with some high level benefits and disadvantages of each method This is not an exhaustive list of all the options that may be available Table 5 1 Virtual Machine Backup Options Backup Option Benefits Disadvantages Install back up softwar
