Limitations of Shadowing

Go Up to Shadowing

Shadowing has the following limitations:

• Shadowing is not an implementation of replication. Shadowing is one-way writing, duplicating every write operation on the master database. Client applications cannot access the shadow file directly.
• 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. Shadowing to a NFS file system or mapped drive is not supported. Shadowing to tape or other media is unsupported.
