Delegate is a great way to implement Callback operation. But, interface is good for the implementation of Callback in different scenario which I have mentioned above. Please read carefully and understand the code snippets. I have also attached code files. Writing code is good but code with proper design approach increases the quality of code.
Windows Vista and Windows 7 make use of a c:\windows\winsxs folder to store backups of various install files and/or files replaced by updates. I'm not completely certain on everything Windows stores there.This seems to be completely separate from System Restore.he WinSxS\Backup folder: In previous versions of Windows, such as XP there was a component called 'Windows File Protection' which was used to make sure that all of the many system files were protected and backed up. These files were backed up in the %systemroot%\System32\dllcache folder.
However, it should be noted that in the case of Exchange server backup is performed: 1  through the use of VSS (Volume Shadow Services) â allows you to recover the database file. 2  or granular backup using to recover from a backup, a single mailbox or emails that are in the mailbox.
