title: 'Configuration'
---

The file `$HOME/.dav/sync.xml` is used for configuring sync-directories.

The *sync.xml* file is an XML file with `<configuration>` as root element. This element can only have `<directory>` elements as children.

## directory

This element configures a sync-directory. A sync-directory must have a unique name, a (local) path, repository and a database.

Required elements: `<name>`, `<repository>`, `<path>`, `<database>` \
Optional elements: `<collection>`, `<trash>`, `<max-retry>`, `<backup-on-pull>`, `<lock-pull>`, `<lock-push>`, `<lock-timeout>`, `<filter>`

### name

Unique sync-directory identifer. This identifer is used in combination with all *dav-sync* commands.

Type: string \
Example: `<name>mysyncdir</name>`

### repository

Name of the WebDAV-repository. A repository with the same name must be configured in [config.xml][1].

Type: string \
Example: `<name>myrepo</name>`

### path

The path of the local directory that should be synchronized. The path must be an absolute path or start with an environment variable. A path with an environment variable must start with an `$` followed by the variable name optionally followed by a path. For example:

	`<path>$HOME/Documents</path>`

The part between `$` and `/` is the environment variable name.

Type: string \
Example: `<path>/absolute/path</path>`

### database

Path to the database file used for this sync-directory. The path must be relative to the *$HOME/.dav/* directory.

Type: string \
Example: `<database>myrepo-db.xml</database>`

### collection

Path of the collection relative to the repository root collection. For example if the repository url is *http://example.com/webdav/* and the collection value is */myfiles/*, the directory is synchronized with *http://example.com/webdav/myfiles/*

Type: string \
Default: / \
Example: `<collection>/myfiles</collection>`

### trash

Path to the trash directory for this sync-directory. Files that should be deleted will be moved to this directory. The value must be an absolute path or relative to the sync-directory path.

Type: string \
Example: `<trash>.trash</trash>`

### max-retry

This integer value controls how many attempts of downloading/uploading a file in case of an error are made.

Type: integer \
Default: 0 \
Example: `<max-retry>3</max-retry>`

### backup-on-pull

If this element has the value of true, the *pull* command will move old local files to the trash directory before downloading the new version from the server. 

Type: boolean \
Default: false \
Example: `<backup-on-pull>true</backup-on-pull>`

### lock-pull

Enables locking for the *pull* command.

Type: boolean \
Default: false \
Example: `<lock-pull>true</lock-pull>`

### lock-push

Enables locking for the *push* command.

Type: boolean \
Default: false \
Example: `<lock-push>true</lock-push>`

### lock-timeout

Specifies the lock timeout in seconds. If the lock-timeout is 0, the client doesn't request a specific timeout and the server's default value is used. If the lock-timeout is -1, a infinite timeout is requested.

Type: integer \
Default: 0 \
Example: `<lock-timeout>50</lock-timeout>`

### filter

With the filter element, include and exclude filters can be specified, to control which files are synchronized. The *pull* and *push* command apply these filters to file paths. At first it is checked if a file is matching any include filter. If so only files matching not an exclude filter are further processed.

Note: The file path is relative to the directory path (and WebDAV collection) but always starts with an path separator.

Optional elements: `<include>`, `<exclude>`

### include

Controls which files will be included by *pull* and *push*. If an include filter is specified, only files matching this filter are included.

Type: regex string \
Default: .* \
Example: 

	<filter>
		<include>\.pdf$</include>
	</filter>

### exclude

Controls which files will be excluded by *pull* and *push*.

Type: regex string \
Example:

	<filter>
		<exclude>^/secretdir</exclude>
		<exclude>\.DS_Store$</exclude>
	</filter>
