Figure 22: Configuring virtual machines and their backup proxy settings
VCBimage backup method
For the VCBimage backup method, you need to have at least one backup proxy system configured in
your environment. A backup proxy system is a Windows system that has the VCB software installed.
For details on the VCB software, see the VMware documentation. During a VCBimage backup, Data
Protector invokes VCB to mount virtual machines on a backup proxy host. Before a virtual machine is
mounted, VCB creates a virtual machine snapshot to put the virtual machine into a consistent state.
Once mounted, the virtual machine is copied (exported) to the backup proxy local disk.
NOTE:
Depending on virtual machine disk sizes, the copy operation can be very
time-consuming. It may take longer than the default Data Protector Session
Manager timeout, which is 10 minutes. If the timeout is reached, the
session is automatically aborted. To solve the problem, extend the timeout
by resetting the Data Protector SmWaitForFirstBackupClient global options
variable. For details, on how to set the variable, see the Data Protector
software online help index: “global options”.
