Turning Crashplan backups on and off Apps
Crashplan is a nifty off-site backup application, but it oddly lacks a setting to turn it off and on. Here's how to do that.

Like other remote backup services it lets you backup your disk to their remote server. What really distinguishes this however is that you can also backup to any friend who is also running Crashplan. Come full-disk restore-time that can be a massive time saver since you can just drive over to your friends house, pick up the disk, and restore your hundreds of gigabytes locally.

Crashplan seems to have only one defect in my opinion. There's no way to turn it off temporarily! You can uninstall it, but that loses all your settings and possibly deletes the backups. You can set its back up times to be none, or you can set it to pause, but that does not stop the application from running, and since it's Java it can be a bit bloated in memory usage. (The reason they don't want you turning it off is because this not only stops your backups to your friend but also your freind's ability to backup and restore from your disk.)

So how do you turn it off temporarily?

Use Launchctl like this:
sudo launchctl stop com.crashplan.engine
sudo launchctl unload /Library/LaunchDaemons/com.crashplan.engine.plist
And to turn it back on:
sudo launchctl load /Library/LaunchDaemons/com.crashplan.engine.plist
sudo launchctl start com.crashplan.engine

[crarko adds: I haven't tested this one. I use a few of the online backup services but Crashplan hasn't been one of them. Feel free to share your experiences in the comments.]

Turning Crashplan backups on and off

There's a built-in, but somewhat hidden, way to do this as well.

In the CrashPlan application, double-click the green house image in the upper-right corner of the window. This will open the advanced command console, along with a list of supported commands.

The one you want is 'sleep'

Just type 'sleep xxxx' and hit enter (with xxxx being the number of minutes you want the CrashPlan backup to sleep)

CrashPlan Pro (I'm not sure about their consumer version) has several built-in commands and even a command line utility for building scripts. The commands are documented here:

This seems like overkill; if you open the Crashplan application interface, you can pause the backup. It will resume automatically in 24 hours, so you don't have to remember to run the re-start command.

You can also access these settings by double-clicking on the crashplan house icon on the top right corner of the app window, and it will reveal a terminal with commands you can input. -Digitol-
