very limited free version

i only tried the free version and the backup task (not the restore task) on wp6.
there is not parameter to store the backuped file outside the wordpress root path, all is store in /upload. So if you lose your wordpress folder, then you lose your backup too! then if you have a override task which perform a daily backup (like another linux app), then your wordpress archive get bigger and bigger each time because there is a ‘inside-backup’ stored each time. that why you need to store the backup archive outside the wordress root path!
