Abstract: A system and methods for backing up and restoring updates to metadata of files stored in a database are disclosed. One example embodiment of the method includes entering the updates to the metadata of the one or more files into a first database table; generating a backup file of the first database table; and restoring the updates to the metadata to the one or more files using the backup file. Restoring the updates may include creating a recovery table populated with data from the backup file; determining the one or more files to apply the updates to by searching the recovery table for an identifier of the one or more files; and adding the updates to the metadata from the recovery table to the corresponding one or more files that matches the identifier identified from the recovery table.
