How to prevent deja-dup-monitor from running, or completely delete it?

My ubuntu is dead after a few minutes because a process called deja-dup-monitor consumes almost 7 GB memory. I searched the internet and found that it seems to be used for backups and related to the "Chrome Remote Desktop". I don't remember installing this software and I don't want to backup something. So what commandline can I use to prevent deja-dup-monitor from running, or to completely delete it or Chrome Remote Desktop? Thanks a lot.

I fix this problem by myself. The deja-dup-monitor is a component of "Deja Dup Backup Tool". When search with keyword "backup", this software appears blatantly in the first place in the Software Center. After uninstalling it, everything will return to order. I then reinstalled this software just to leave a review warning people not to install it, if they don't want their ubuntu to die, and uninstall it immediately in a hurry.

I am curious about the development team of this software. Does developers in this team all have a computer with 256GB memory so that no one found this problem? or they are so bold-faced to write a rubbish software to make them happy by seeing their users hit their heads against a wall. If I wrote such a code (yes I sometimes did because I'm not a genius), I will feel so ashamed that I will fix this memory leakage bug (or something) as soon as possible even after two or three sleepless nights.

Something about installing Chrome Remote Desktop causing this app to start misbehaving. Uninstalling it as described above does the trick.

There is an open bug at launchpad: deja-dup monitor was taking 6GB of memory.
