I am curious how "Volume Shadow Copy" works in Windows system.
I understand that during a Windows backup, the Windows actually creates a volume shadow copy of your data to create an accurate point-in-time copy of the contents of your hard drive, including any open files or files that are being used by the system.
However, if the file is very huge and is in used (say 5-10 GB in size) then, how "Volume Shadow Copy" can manage to do a snap shot in one go?
Does it has the similar concept of using "archive log" (like Oracle)? Thanks.
