Hi, Denis! Thanks for your valuable input. So, in case I have to backup lot of small files and only some of them are changed I should go with rsnapshot. If there are big text files that changes through time, I should go with rdiff-backup. Would it be reasonable to use them both where appropriate or thats just unnecessary complexity?
