Go Up to Creating a Database Shadow


Shadowing has the following limitations:

  • Shadowing is useful only for recovery from hardware failures or accidental deletion of the database. User errors or software failures that corrupt the database are duplicated in the shadow.
  • Recovery to a specific point in time is not possible. When a shadow is activated, it takes over as a duplicate of the database. Shadowing is an “all or nothing” recovery method.
  • Shadowing can occur only to a local disk. InterBase does not support shadowing to an NFS file system, mapped drive, tape, or other media.
