By using hotcopy this can be performed on a live subversion repository and will produce a pristine backup.

#!/bin/bash
REPOS_PATH=/var/repos
mkdir -p /backups/weekly
rm -rf /backups/tmp
mkdir -p /backups/tmp/repos
for i in $(ls $REPOS_PATH); do
        /path/to/svnadmin hotcopy $REPOS_PATH/$i /backups/tmp/repos/$i
done
FN=svn.weekly.`date '+%Y%m%d'`.tar.gz
tar -czf /backups/weekly/$FN -C /backups/tmp .

Edit the file .subversion/config and scroll down towards the bottom... find the [miscellany] block and uncomment the line enable-auto-props = true

In the group of options below titled [auto-props] and add a line like:

* = svn:keywords=Id Date LastChangedBy Revision

Assuming you're past the point where you have a repository with files already under version control, you simply add in wherever you want the substitution to occur the variable name surrounded by $.

/* SVN: $Id$ */
/**
 * Short Description
 *
 * Long Description
 *
 * @package			mypackage
 * @lastmodified	$Date$
 * @modifiedby		$LastChangedBy$
 * @version			$Revision$
 */

Then you run the svn propset command in your working directory:

svn propset svn:keywords "Id Date LastChangedBy Revision" . -R

Remember, you need to set properties to all new files you add, this is NOT done automatically!
