simple backup with rsync

With this cron, rsync begins to sinchronize the contents of the local directory on /[VIPdirectory] with the directory /backup/[VIPdirectory] on the remote server X.X.X.X. Previously we need working on public/private-keys ssh to guarantee the acces to the remote server on X.X.X.X

ps -ef | grep PROCESS | grep -v grep | awk '{print $2}' | xargs kill -9

kills all pids matching the search term of "PROCESS". Be careful what you wish for :)
