## svnadmin—Subversion Repository Administration

svnadmin is the administrative tool for monitoring and repairing your Subversion repository. For detailed information on repository administration, see the maintenance section for the section called “svnadmin”.

Since svnadmin works via direct repository access (and thus can only be used on the machine that holds the repository), it refers to the repository with a path, not a URL.

### svnadmin Options

Options in svnadmin are global, just as they are in svn:

`--bdb-log-keep`

  (Berkeley DB-specific.) Disable automatic log removal of database logfiles. Having these logfiles around can be convenient if you need to restore from a catastrophic repository failure.

`--bdb-txn-nosync`

  (Berkeley DB-specific.) Disables fsync when committing database transactions. Used with the svnadmin create command to create a Berkeley DB-backed repository with `DB_TXN_NOSYNC` enabled (which improves speed but has some risks associated with it).

`--bypass-hooks`

  Bypass the repository hook system.

`--bypass-prop-validation`

  When loading a dump file, disable the logic which validates property values.

`--clean-logs`

  Remove unused Berkeley DB logs.

`--config-dir` `DIR`

  Instructs Subversion to read configuration information from the specified directory instead of the default location (`.subversion` in the user's home directory).

`--deltas`

  When creating a repository dump file, specify changes in versioned properties and file contents as deltas against their previous state.

`--fs-type` `ARG`

  When creating a repository, use `ARG` as the requested filesyste type. `ARG` may be either `bdb` or `fsfs`.

`--force-uuid`

  By default, when loading data into a repository that already contains revisions, svnadmin will ignore the UUID from the dump stream. This option will cause the repository's UUID to be set to the UUID from the stream.

`--ignore-uuid`

  By default, when loading data into an empty repository, svnadmin will set the repository's UUID to the UUID from the dump stream. This option will cause the UUID from the stream to be ignored.

`--incremental`

  Dump a revision only as a diff against the previous revision, instead of the usual fulltext.

`--memory-cache-size` (`-M`) `ARG`

  Configures the size (in Megabytes) of the extra in-memory cache used to minimize redundant operations. The default value is `16`. (This cache is used for FSFS-backed repositories only.)

`--parent-dir` `DIR`

  When loading a dump file, root paths at `DIR` instead of `/`.

`--pre-1.4-compatible`

  When creating a new repository, use a format that is compatible with versions of Subversion earlier than Subversion 1.4.

`--pre-1.5-compatible`

  When creating a new repository, use a format that is compatible with versions of Subversion earlier than Subversion 1.5.

`--pre-1.6-compatible`

  When creating a new repository, use a format that is compatible with versions of Subversion earlier than Subversion 1.6.

`--revision` (`-r`) `ARG`

  Specify a particular revision to operate on.

`--quiet` (`-q`)

  Do not show normal progress—show only errors.

`--use-post-commit-hook`

  When loading a dump file, runs the repository's `post-commit` hook after finalizing each newly loaded revision.

`--use-post-revprop-change-hook`

  When changing a revision property, runs the repository's `post-revprop-change` hook after changing the revision property.

`--use-pre-commit-hook`

  When loading a dump file, runs the repository's `pre-commit` hook before finalizing each newly loaded revision. If the hook fails, aborts the commit and terminates the load process.

`--use-pre-revprop-change-hook`

  When changing a revision property, runs the repository's `pre-revprop-change` hook before changing the revision property. If the hook fails, aborts the modification and terminates.

`--wait`

  For operations which require exclusive repository access, wait until the requisite repository lock has been obtained instead of immediately erroring out when it cannot be.
