Testing backups in the clouds

2011-06-18

I am currently testing out CrashPlan as an option for backing up in the clouds. In addition to the documents I use on a daily basis, I have extra disks with documentation of past projects (video, images, sound, etc) and a disk for audio files. Loosing the content of these would be pretty disastrous. Although I do regular backups, the original and backup disks to often end up sitting next to each other.

CrashPlan seems user-friendly and reasonably priced and I’ll give it a go for the free test month and see how it works. I just need to ensure that I am not uploading to the clouds when connected to internet using iPhone tethering, or my monthly bandwidth will be soon gone.

To prevent this, I followed suggestions in this thread and installed the freeware software Marco Polo, a simple context-aware program. I have added a context for iPhone teethering. Hopefully Marco Polo will discover when I’m teethering based on the IP address. It will then run the following AppleScript when I start tethering:

do shell script "launchctl unload -w /Library/LaunchDaemons/com.crashplan.engine.plist &" with administrator privileges

and the following script when I stop teethering:

do shell script "launchctl load -w /Library/LaunchDaemons/com.crashplan.engine.plist &" with administrator privileges

Both scripts should be one line only when pasted into Script Editor.
