Oracle ACFS runs on operating system platforms as a native file system technology supporting native operating system file system application programming interfaces (APIs). Consequently, backup applications that access files using the native operating system file system interfaces are able to access and backup Oracle ACFS file systems and other native operating system file systems. Oracle ACFS snapshots can be dynamically created and used to present a consistent, on-line view of an active file system to a backup application.
Backup applications that use interfaces other than the standard operating system interfaces (read or write) are not supported with Oracle ACFS. For example, Windows backup applications that depend upon the presence of reparse points or the Windows Volume Shadow Copy Service (VSS) are not supported.
