query on WOFB

Hi All,

I need your help in understanding how the WOFB works if we enable that option in the Client Attributes, as per my understanding an VSS snapshot is created before we start the backup(please correct me if I am wrong), if so where those snap shots will be stored ?.

I do see the shadow copies option is disabled on the server's local drives. I am just little bit confussed on the Shadow copies on the drives and the VSS snapshots. Please let me know whether they are related to each other. some time I was told by co- worker increasing the shadow copies space will fix the backup problem.
