# File Replication

## Key Terms

### Batch Replication

This term describes a replication mode of the File Replication Module (DFM). In this mode, files are transferred in regular intervals and at times specified in the corresponding replication order.

### DDM

Distributed Data Management describes the working principle of the General Replication Module (DDM), the File Replication (DFM), and the Data Distribution Module (EER). The General Replication Module (DDM) manages data that is distributed over several locations and vaults and which can be accessed with the other two modules.

### DFM

Distributed File Management describes the function of the File Replication Module (DFM).

### Local Vault

This vault is located at a specific local site and stores replicated data.

### Replication, Data Replication

Exchange of data (e.g. document files or files containing meta data) between several distributed locations. The files are later stored in the local vault.

### File Replication Module (DFM)

This module controls the replication of document files for several distributed sites. The file transfer mode is selected as part of the check-out procedure: The transfer may be initiated immediately or at a specific time (initiated using a batch process). Files are distributed with the FileSever module. Document files are then stored in the local vault.
