Auto Backup/Sync specific folders to USB drive?

Just out of curiosity, why do you want "something like Time Machine?" Time machine does what you appear to want.....

If the "specific folder" was changed, it would be backed up.

... i would like for it automaticly backup when USB is connected is there a software for that?

You can use launchd.

First, use this script to perform the backup:

(change "~/Documents/" to the Folder to backup

and "/Volumes/MYUSB" to your USB name)

#!/bin/bash

sleep 10

if [[ -d "/Volumes/MYUSB" ]] ; then

/usr/bin/rsync -a "~/Documents/" "/Volumes/MYUSB"

fi

Then put this plist file in ~/Library/LaunchAgents/ and Log oot and back in (or reboot)

(change /Users/Tony/Desktop/backupMyUSB.sh to the name and location of the script that you created above)
