Is there an app to remote backup with rsync?

Thanks for the reply.

I’ve got around the EX2’s habit of removing the scripts and keys by storing them on the physically mounted drive and copying them into the home directory when the rsync script is triggered. Just need to get around the crontab reset now, but I see some others have managed this by modifying config.xml to add a new crontab entry:

I’m a little bit loathe to test this in case it stops the device from booting if I get it wrong. Would a factory reset restore it if it did?
