Abstract
Provided are a computer program product, system, and method for using a metadata image of a file system and archive instance to restore files in the file system. A metadata image of the file system for a point-in-time backup as of a point-in-time includes information on files and directories in the file system as of the point-in-time and an archive instance including a copy of database records in the backup database for the files in the point-in-time backup. A restore request is received. A file representation is created of each file to restore in the directory structure of the file system from the metadata image, wherein at least one of the created file representations indicates that the file is stored off-line and has an external identifier used to access information on the file in the database records in the archive instance for the point-in-time backup.
