Version Control with Subversion, 2nd Edition

Name

svnadmin dump — Dump the contents of the filesystem to stdout.

Synopsis

svnadmin dump REPOS_PATH [-r LOWER[:UPPER]] [--incremental]

Description

Dump the contents of the filesystem to stdout in a “dump file” portable format, sending feedback to stderr. Dump revisions LOWER rev through UPPER rev. If no revisions are given, dump all revision trees. If only LOWER is given, dump that one revision tree. See Migrating Repository Data Elsewhere for a practical use.

By default, the Subversion dump stream contains a single revision (the first revision in the requested revision range) in which every file and directory in the repository in that revision is presented as though that whole tree was added at once, followed by other revisions (the remainder of the revisions in the requested range), which contain only the files and directories that were modified in those revisions. For a modified file, the complete full-text representation of its contents, as well as all of its properties, are presented in the dump file; for a directory, all of its properties are presented.

Two useful options modify the dump file generator’s behavior. The first is the --incremental option, which simply causes that first revision in the dump stream to contain only the files and directories modified in that revision, instead of being presented as the addition of a new tree, and in exactly the same way that every other revision in the dump file is presented. This is useful for generating a relatively small dump file ...
