# File archiving

The Commvault file archiving solution enables you to move data to a secondary storage and use it to function as an archive copy. You can move data to disk, tape, or cloud libraries. The archived data will be available for quick and easy retrieval.

You can recall the archived data by using stubs or placeholders in the original locations. Stubs are retained in the primary storage, which points to the data that was moved as part of the archive operation. You can also delete files from the source server using the archive feature.

You can use archiving reports to view vital information, such as the compression rate and the application size.

Note

You cannot use the Command Center to edit the properties of archiving clients created using the CommCell Console.

## Key Features

- Archiving enables you to easily manage the backup data in your environment, by providing pre-defined archiving rules.

- Files are indexed when you perform archive operations, so you can search and retrieve archived files easily.

## Support

You can archive data on the following types of clients:

Clients | Agents
--- | ---
File system | Windows UNIX
Network file system | NAS NetApp EMC Celerra Hitachi NAS (VSP One File), EMC Unity, and Isilon Network share
Big data | Hadoop (HDFS) IBM Spectrum Scale (GPFS) Lustre

## Terminology

- Archiving: Archiving is a process of periodically moving unused or infrequently used data on a host computer to secondary storage, thereby reducing the size of data on the primary storage.

- Stub: Stubs are placeholders of the original data after it has been migrated to the secondary storage. Stubs replace the archived files in the location selected by the user during the archive. However, stubs will only be created if the subclient properties were configured to create them during archive.

- Stub Recall: If the subclient is configured to create stubs, you can perform a recall operation from the client computer for recovering the stubs. A recall is any action that causes an open and read to be executed on the stub, which automatically initiates a recovery operation.

- Data Recovery: Archived data can be recovered using any of the following methods within the Command Center:

  1. Path-Based Recovery: Recover archived files by specifying file paths directly through the Command Center interface.

  2. Browse and Restore: Use the Browse and Restore feature in Command Center to navigate and select archived files for recovery.

  3. Stub Recall via Third-Party Tools: Recall archived files from stubs using third-party applications such as Windows Terminal or other command-line interfaces.
