Abstract
A system for archiving composite files including metadata and payload data in a file system. In at least one embodiment, the system includes a database for storing, in particular exclusively, a first group of metadata of the archived composite files, corresponding to search criteria usable in a query; at least one information layer in the file system for storing a second group of metadata of the archived composite files in storage files, the second group in particular including the metadata of the first group and/or all metadata; and the archived composite files stored in the file system.
Claims21
A computer device for archiving composite files in a file system, the composite files including metadata and payload data and the computer device comprising:
- a non-transitory memory including a database configured to exclusively store a first group of metadata of the archived composite files, the first group of metadata corresponding to search criteria usable in a query, the first group of metadata including only a subset of the metadata included in the composite files, and the subset of the metadata including less than all metadata included in the composite files;
- at least one information layer in the file system configured to store a second group of metadata of the archived composite files in storage files, the second group of metadata including at least the metadata of the first group;
- and
- the archived composite files stored in the file system;
- wherein
- the computer device archives the composite files in the file system, and
- the composite files include the metadata and the payload data.
A method for operating a system for archiving composite files in a file system, the composite files including metadata and payload data and the method comprising:
- archiving the composite files in the file system;
- storing, exclusively in a database, a first group of metadata of the archived composite files, the first group of metadata corresponding to search criteria usable in a query, and the first group of metadata including only a subset of the metadata included in the composite files, and the subset of the metadata including less than all metadata included in the composite files;
- and
- storing a second group of metadata of the archived composite files, the second group of metadata including at least the metadata of the first group, in storage files in at least one information layer in the file system;
- wherein
- the composite files include the metadata and the payload data.
