RestoreResource Method
Restores a given file resource revision.
Syntax
dropbox.restoreResource(revision, toResourcePath, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This method restores a the specified Revision of a file resource, saving it to the given path ToResourcePath. Restoring a deleted file resource can also be done using this method as long as the revision Id is known (there's no way to obtain revision Ids for file resources which have already been deleted; this is a limitation of the Dropbox API).
Revision must be a revision Id. ToResourcePath must be a file path (and it must end with the desired name of the file resource being restored).
