I have Crashplan and it is constantly running in the background and making backups every 15 minutes. It caused some problems with the backup target folders, so I want it to be inactive while I am making changes to these folders.

I started the application itself, but could not find some kind of "Pause" button. So I decided to just stop its process. I first tried the lazy way - the system monitor in the Gnome panel has a "Processes" tab - but didn't find it listed there. Then I did a sudo ps -A and read through the whole list.

I don't recognize everything on the list (many process names are self-explaining, like evolution-alarm, but I don't recognize others like phy0) but there was nothing which sounded even remotely like crashplan. But I know that there must have been a process belonging to Crashplan running at this time, because the main Crashplan window was open when I ran the command.

Do you have any advice how to stop this thing from running? The best solution would involve temporary preventing it from loading on boot too, since I may need to reboot while doing the maintenance there.
