Abstract
A method and system for backing up and restoring data in a file system that includes junctions is provided. In a backup operation, a junction is encoded as a symbolic link (“symlinkâ€) directive, and sent with a sequential image data stream in the backup operation and written to a tape or disk. In a restore operation, when the encoded symlink directive is encountered after data is read from the tape, the symlink is decoded by an administrator to obtain the embedded junction information contained in the symlink directive. The administrator can then recreate the junction using the information. The junction information is thereby transmitted as part of the backup and restore operation while remaining transparent to third party software performing the backup and restore processes.
