The filesystem 'dump' format contains nothing but the abstract structure of the filesystem -- independent of any internal node-id schema or database back-end. All of the data in the dumpfile is acquired by public function calls into svn_fs.h. Similarly, the parser which reads the dumpfile is able to reconstruct the filesystem using only public svn_fs.h routines.
Thus the dump/load feature's main purpose is for *migrating* data from one svn filesystem to another -- presumably two filesystems which have different internal implementations.
If you simply want to backup your filesystem, you're probably better off using the built-in facilities of the DB backend (using Berkeley DB's hot-backup feature, for example.)
For a description of the dumpfile format, see /trunk/notes/fs_dumprestore.txt.

Dump the contents of the filesystem within already-open repos into writable dumpstream. Begin at revision start_rev, and dump every revision up through end_rev. Use pool for all allocation. If non-NULL, send feedback to feedback_stream. If dumpstream is NULL, this is effectively a primitive verify. It is not complete, however; svn_repos_verify_fs2() and svn_fs_verify().
If start_rev is SVN_INVALID_REVNUM, then start dumping at revision 0. If end_rev is SVN_INVALID_REVNUM, then dump through the HEAD revision.
If incremental is TRUE, the first revision dumped will be a diff against the previous revision (usually it looks like a full dump of the tree).
If use_deltas is TRUE, output only node properties which have changed relative to the previous contents, and output text contents as svndiff data against the previous contents. Regardless of how this flag is set, the first revision of a non-incremental dump will be done with full plain text. A dump with use_deltas set cannot be loaded by Subversion 1.0.x.
If notify_func is not NULL, then for every dumped revision call notify_func with rev set to the dumped revision and warning_text NULL. For warnings call notify_func with warning_text.
If cancel_func is not NULL, it is called periodically with cancel_baton as argument to see if the client wishes to cancel the dump.

Set *parser and *parse_baton to a vtable parser which commits new revisions to the fs in repos. The constructed parser will treat UUID records in a manner consistent with uuid_action. Use pool to operate on the fs.
start_rev and end_rev act as filters, the lower and upper (inclusive) range values of revisions in dumpstream which will be loaded. Either both of these values are SVN_INVALID_REVNUM (in which case no revision-based filtering occurs at all), or both are valid revisions (where start_rev is older than or equivalent to end_rev).
If use_history is set, then the parser will require relative 'copyfrom' history to exist in the repository when it encounters nodes that are added-with-history.
If validate_props is set, then validate Subversion revision and node properties (those in the svn: namespace) against established rules for those things.
If parent_dir is not NULL, then the parser will reparent all the loaded nodes, from root to parent_dir. The directory parent_dir must be an existing directory in the repository.

Read and parse dumpfile-formatted dumpstream, reconstructing filesystem revisions in already-open repos, handling uuids in accordance with uuid_action. Use pool for all allocation.
If the dumpstream contains copy history that is unavailable in the repository, an error will be thrown.
The repository's UUID will be updated iff the dumpstream contains a UUID and uuid_action is not equal to svn_repos_load_uuid_ignore and either the repository contains no revisions or uuid_action is equal to svn_repos_load_uuid_force.
If the dumpstream contains no UUID, then uuid_action is ignored and the repository UUID is not touched.
start_rev and end_rev act as filters, the lower and upper (inclusive) range values of revisions in dumpstream which will be loaded. Either both of these values are SVN_INVALID_REVNUM (in which case no revision-based filtering occurs at all), or both are valid revisions (where start_rev is older than or equivalent to end_rev).
If parent_dir is not NULL, then the parser will reparent all the loaded nodes, from root to parent_dir. The directory parent_dir must be an existing directory in the repository.
If use_pre_commit_hook is set, call the repository's pre-commit hook before committing each loaded revision.
If use_post_commit_hook is set, call the repository's post-commit hook after committing each loaded revision.
If validate_props is set, then validate Subversion revision and node properties (those in the svn: namespace) against established rules for those things.
If non-NULL, use notify_func and notify_baton to send notification of events to the caller.
If cancel_func is not NULL, it is called periodically with cancel_baton as argument to see if the client wishes to cancel the load.

| ) |
Read and parse dumpfile-formatted stream, calling callbacks in parse_fns/parse_baton, and using pool for allocations.
If deltas_are_text is TRUE, handle text-deltas with the set_fulltext callback. This is useful when manipulating a dump stream without loading it. Otherwise handle text-deltas with the apply_textdelta callback.
If cancel_func is not NULL, it is called periodically with cancel_baton as argument to see if the client wishes to cancel the dump.
This parser has built-in knowledge of the dumpfile format, but only in a limited sense:
* it recognizes the "magic" format-version header.
* it recognizes the UUID header.
* it recognizes revision and node records by looking for either a REVISION_NUMBER or NODE_PATH headers.
* it recognizes the CONTENT-LENGTH headers, so it knows if and how to suck up the content body.
* it knows how to parse a content body into two parts: props and text, and pass the pieces to the vtable.
This is enough knowledge to make it easy on vtable implementors, but still allow expansion of the format: most headers do not have to be handled explicitly.

Verify the contents of the file system in repos.
If feedback_stream is not NULL, write feedback to it (lines of the form "* Verified revision %ld\n").
If start_rev is SVN_INVALID_REVNUM, then start verifying at revision 0. If end_rev is SVN_INVALID_REVNUM, then verify through the HEAD revision.
For every verified revision call notify_func with rev set to the verified revision and warning_text NULL. For warnings call notify_func with warning_text set.
If cancel_func is not NULL, call it periodically with cancel_baton as argument to see if the caller wishes to cancel the verification.
