Abstract
Provided are a computer program product, system, and method for using a metadata image of a file system and archive instance to backup files in the file system. A point-in-time backup is performed of files in the file system as of a point-in-time. A metadata image includes information on files and directories in the file system as of the point-in-time. Files in the point-in-time backup are backed up to a backup storage. A backup database has records on the files backed-up from the file system. Each record in the backup database has a unique identifier for each backed-up file and a location of the backed-up file in the backup storage. An archive instance is generated including a copy of the database records for the files in the point-in-time backup. The metadata image and the archive instance are associated for the point-in-time backup.
