Очень часто перед очередным развертыванием веб-приложения встает задача по резервному копированию старой версии (на случай падения), чтобы если что, можно было бы откатиться до неё. Если для развертывания вы используете Apache Ant, то можно создать для него цель (target) и для резервирования данных.

В примерах чаще всего предлагают следующий код:

<target name=”prepare”>
<tstamp>
<format property=”timestamp” pattern=”dd-MM-yyy-HH-mm”/>
</tstamp>
</target>

<target name=”backup” depends=”prepare”>
<tar destfile=”/opt/teamcity/backups/${timestamp}.tar.gz” compression=”gzip”>
<tarfileset dir=”/opt/teamcity/projects/myproject”>
</tarfileset>
</tar>
</target>

Однако, если вы попробуете сделать бекап проекта на ZendFramework таким образом, вы словите много ошибок, типа вот этих:
