Abstract
In an approach to maintain data integrity in a computer data storage system, a clone management table is generated for a clone file tree that includes a relationship between at least one parent file and a clone file. The parent file is restored by: (i) determining that the parent-child relationship exists between the parent file and the clone file based on an entry in the clone management table, (ii) restoring data blocks in the parent file to the file system based on an analysis of an entry in the clone management table for the parent file and an identification of data blocks included in the clone file, and (iii) generating a new instance of the parent file based on the data blocks included in the file system and the entry in the clone management table for the clone file tree.
