<p>A method and system for backing up and restoring single instance store (SIS) files comprising links to common store files. A dynamic link library (DLL) including an interface enables a backup/restore application to properly backup and restore SIS-enabled volumes including SIS links and their corresponding store files. For each link to be backed up, the DLL tracks whether its corresponding common store file has already been identified for backing up to the backup application, such that it is identified only one, whereby only one copy of a common store file is backed up per volume, regardless of the number of additional links pointing thereto. For each link to be restored, the DLL tracks whether its corresponding common store file has already been identified for restoring to the restore application, or is already present on the volume, whereby a common store file for a link file is only restored to a volume only once and if not already present on that volume.</p> |
