  • Database backup and restore with integrated index reorganization
    Patent number: 8626717
    Abstract: A mechanism is provided for reorganizing a source index tree of a database table resulting in a target index tree of the database table is provided. A backup process reads source leaf pages of the source index tree in a logical order defined by a sequence of index keys. The logical order can be different from a physical order of the source leaf pages defined by a sequence of respective storage locations. The backup process constructs target leaf pages of the target index tree maintaining the logical order. A restore process constructs target non-leaf pages of the target index tree based on the distribution of the index keys among the constructed leaf pages and stores the target leaf and non-leaf pages.
