IIS provides three methods to back up the metabase. Using Configuration Backup/Restore, you can create a secure backup or insecure backup of your metabase. With the new functionality to Configuration Backup/Restore in the IIS snap-in, Web site administrators can also restore copies of the metabase to other computers. These back up methods provide a way to restore only your metabase settings, not your content files. As with previous versions of IIS, you can programmatically create a legacy backup of the metabase; however, you can not restore legacy backups of the metabase to other computers.
Secure BackupInsecure Backup
Using this method, the Web site administrator chooses not to supply a password. The metabase backup is encrypted with a blank password and anyone can restore the metabase backup. See To create an insecure backup (Password Not Required)
Legacy Backup
Using this method, the Web site administrator can create metabase backups programmatically. However, they must be restored either programmatically or using Configuration Backup/Restore from the IIS snap-in.
Important The legacy back up method is not recommended and therefore not described. When you create backups programmatically, IIS implements the legacy method used in IIS 5.0. Therefore, you can only restore legacy metabase backups to the operating system on which the backup was created.
