DEDUP_CONTAINER_EXTENT structure

-description

A logical container file may be stored in a single segment or multiple segments in the backup store. DEDUP_CONTAINER_EXTENT represents a single extent of a specific container file as stored in the backup store. The extent may be the full container file or a portion of the file.

-struct-fields

-field ContainerIndex

The index in the container list passed to IDedupReadFileCallback::OrderContainersRestore to which this container extent structure corresponds.

-field StartOffset

Offset, in bytes, from the beginning of the container to the beginning of the extent.

-field Length

Length, in bytes, of the extent.

-remarks

For example, in an incremental backup scheme, the container may reside in the store either as one complete file generated in a full backup, or as multiple incremental files that contain changes in the file since the previous backup.
