Share your user experience with Comodo Backup, Time machine

[Ashwin]

I would like to know if any members here have used Comodo's free products like

Comodo Backup
Comodo Time machine

I have read some good reviews about them, but would like to hear some first hand user experience. (Reliability, user-friendliness ,etc)

And also about Comodo System cleaner and Comodo antispam.

How effective are they? And is Comodo Sys cleaner safe to use? (aggressivenes, effectiveness etc)
