Abstract

In an approach to backup and restore one or more clone file trees, one or more processors generate a clone management table. One or more processors record a clone management information in the clone management table about each clone file. To backup a clone file, one or more processors update the clone management information, and store one or more data blocks that are in the clone file trees. To restore a clone file, one or more processors analyze a clone management information and restore one or more data blocks in the clone file. To restore a clone file parent, one or more processors analyze a clone management information and restore one or more data blocks in the clone file parent. To restore a clone file tree, one or more processors analyze a clone management information and restore one or more data blocks in the clone file tree.
