In the DCE Local File System (DCE LFS), a fileset is defined as a collection of related files that are organized into a single, easily managed unit. Because DCE LFS filesets are usually smaller in size than standard file systems, and because each DCE LFS aggregate can house multiple DCE LFS filesets, DCE LFS filesets are easily moved between File Server machines to facilitate load balancing across the network. It is also easy to place read-only copies (replicas) of DCE LFS filesets on different machines in your cell. These multiple copies prevent machines from becoming overburdened with requests for files from popular filesets.
In other operating systems, a file system typically occupies more disk space and is tied to a physical location. In addition, non-DCE LFS file systems (non-DCE LFS filesets) cannot be replicated in DFS.
This topic provides detailed information about how to create, replicate, and back up DCE LFS filesets, and how to mount DCE LFS and non-DCE LFS filesets for use in the DCE namespace. It also explains how to export aggregates and partitions. (See Managing Filesets for information on the tasks involved in the use and maintenance of filesets.)
Note: This guide uses the term non-LFS to refer to non-DCE LFS filesets and aggregates.
