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!

Good security and works flawlessly. I'm mostly running them in "lazy mode", which means the backup daemon picks up changed files after a while and sends them to the backup server. All backup clients uses SSL certificate so all data is transferred and stored encrypted on the server as well. In addition to a neat simple "manual soft RAID" solution, where data can be spread over three directories. I'm in the process now of setting up rsync of these directories to separate storages outside the building. As if one of these directories are "lost" or stolen, the data makes no sense unless you get a copy of another directory to build up the third directory. And considered each backup client uses separate encryption keys, the security is still good. boxbackup.org The only disadvantage I've found is that the restore features can be a bit cumbersome, and dates on directories are not preserved so well. Windows client support exists, but if you have files bigger than 2GB, they need to be restored on a Linux box. So nothing big and amazing, but slightly more advanced than rsync and simpler than Bacula or Amanda backup. kind regards, David Sommerseth
