i have: "SERVER A" "SERVER B" with "full root permisson" [ssh, etc] each server has a folder. i want to backup a folder in "SERVER A". are there any backup methods, that meets these two requirements? : 1) running from e.g.: a cronjob 2) when running, it just checks the folder in "SERVER A" and "SERVER B". if a file/folder has been added/removed/modified in the "SERVER A"'s folder, then it copies/removes it/them to "SERVER B"'s folder. please help! Thank you in advance! [for any links, howtos :\ ] have a nice weekend
