Title: Which backup method takes longer - File or Raw mode in VMWARE?
If the backup software is installed on the same VM - File mode backup would take longer, since the VM is mounted to the backup proxy server and the data transfer still goes through the fiber cable (in case the VMs are on SAN LUN). Raw mode backup exports the VM files to the backup proxy server, which are further backed up by ARCserve Server directly. In any case RAW mode backup would prove faster than File Mode backup.
