Data Deduplication API
Overview of the Data Deduplication API technology.
To develop Data Deduplication API, you need these headers:
For programming guidance for this technology, see:
Enumerations
| DEDUP_BACKUP_SUPPORT_PARAM_TYPE Indicates whether Data Deduplication should perform an unoptimized or optimized restore. |
Functions
| OrderContainersRestore This method provides the application with the ability to influence the order of the pending reads that are required to retrieve the target file. |
| PreviewContainerRead Provides the application with a preview of the sequence of reads that are pending for a given container file extent. |
| ReadBackupFile Reads data from a Data Deduplication store metadata or container file located in the backup store. |
| RestoreFiles Reconstructs a set of files from a backup store that contains the fully optimized version of the files (reparse points) and the Data Deduplication store. |
Interfaces
| IDedupBackupSupport Provides a method for restoring a file from a backup store containing copies of Data Deduplication reparse points, metadata, and container files. |
| IDedupReadFileCallback A callback interface, implemented by backup applications, that enables Data Deduplication to read content from metadata and container files residing in a backup store and optionally improve restore efficiency. |
Structures
| DDP_FILE_EXTENT DDP_FILE_EXTENT represents the extent of data in a file that is to be read in a pending call to ReadBackupFile. |
| DEDUP_CONTAINER_EXTENT A logical container file may be stored in a single segment or multiple segments in the backup store. |
