[Trisquel-users] Seeking for a backup tool

[myself600]

To be short, I am searching for an application with a user interface, that  
supports updating/refreshing readily available partition image clones, so  
that I does not need to create a full drive backup every-time I make a  
backup. I already used Clonezilla to backup two internal notebook hard drives  
with success, but AFAIK it does not support this feature. Any suggetions?
