Introduction

This script saves macos x data onto an remote time machine.

The way it works

• check whether the macos is at home. The script continues only in this case.
• wakes the remote time machine up if it is offline
• saves the data if the time machine is available
• shuts down the remote time machine if it was offline

Howto start the backup

• clone this repo
• instantiate the backup class and call the method startBackupProcess in a starterfile. Example:

backup = Backup.new "00:23:45:87:09:12", "192.168.0.1", "192.168.0.255", "admin", 120, true  
backup.startBackupProcess  

• create a file for the launchd-daemon in the folder ~/Library/LaunchAgents example org.mydomain.mybackup.plist Example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
	<dict>
		<key>Label</key>
		<string>org.mydomain.mybackup</string>
		<key>ProgramArguments</key>
		<array>
			<string>/Users/joscha/backupStarter.rb</string>
		</array>
		<key>StartInterval</key>
		<integer>3600</integer>
		<key>StandardErrorPath</key>
		<string>/Users/joscha/backupError</string>
		<key>StandardOutPath</key>
		<string>/Users/joscha/backupOutput</string>
	</dict>
</plist>

• active the new job. Example:

launchctl load ~/Library/LaunchAgents/org.mydomain.mybackup.plist

• deactivate the automatic time maschine backup
