Python Example of Calculating the Size Needed To Store the Backup Image

This example shows how to use Python to collect the information you need to calculate the size needed to store a backup image of the vCenter Server instance.

from com.vmware.appliance.recovery.backup_client import Parts

 # This example assumes you have previously created a session
 # and stored the session ID in my_stub_config.

 # Issue a request to list the backup image parts.
 Parts_stub = Parts( my_stub_config )
 parts = Parts_stub.list()

 # Extract IDs of backup image parts.
 sizes = {}
 total = 0
 for part in parts :
    size = Parts_stub.get( part.id )
    sizes[part.id] = size
    total += size

 # Show the result.
 print( 'Backup image parts:' )
 for part_id in sizes.keys() :
    print( '  part {0} = {1}KB'.format( part_id, sizes[part_id] ) )
    print( 'Total size: {0}KB'.format( total ) )
