Modifying the Backed Up Data

After mapping the backup instance to a drive letter by using the Mapping Procedure, you can close Catalogic DPX then open, read, copy, create, and modify files.

Typically, you would unmap the server drive letter that became unavailable due to a failure, then map the backup instance to the same drive letter on the application server.

Modifications are stored on the secondary in a “live data” area associated with the LUN, but data in the original backup instance are not modified.

To restore only the Block backup instance, follow the steps in Restoring Data with Block Restore.
