Abstract

This invention performs a DFS (Distributed File System) fts clone to create a backup fileset of individual filesets within a DCE (Distributed Computing Environment) cell while excluding one or more filesets and/or fileset tree structures which are specified in a user-defined exclusion list. In addition, individual filesets within a fileset tree structure which would be excluded via the exclusion list may be included in the clone process by specifying the fileset(s) name(s) in a user-specified inclusion list.

Selective Fileset Backup Cloning When Using DFS butc

A program is disclosed that allows rules to be defined in determining which Distributed File System (DFS) filesets will have a backup fileset created by the fts clone command, which DFS filesets and/or fileset tree structures will be excluded from having a backup fileset created by means of a user-specified exclusion list, and which DFS filesets, if in a fileset tree structure specifically excluded by the exclusion list, may be explicitly specified to to have a backup fileset created by means of a user-specified inclusion list.

This program works by sequentially reading the fileset headers of the DFS filesets hosted on a DFS file server node. The fileset name is parsed from the fileset header information and matched against the fileset name patterns in the user-specified exclusion list. If there is not a match, a backup fileset of the fileset is created using the clone command from the DFS fts command suite. If the fileset name is found to match a fileset name pattern specified in the exclusion list, a backup fileset is not created and the next fileset header is read. Once all fileset headers have been read and acted upon, the entries in the user-specified fileset inclusion list are read sequentially and a backup fileset is created for each using the clone command from the DFS fts command suite.

The benefits of using this method to create backup filesets of DFS filesets within a Distributed Computing Environmen...
