I am a part of a non-profit communitiy that owns two home servers on different locations... I would like to backup some directories from one server to another and vice-versa. The script should be automated, so therefore using RSA private keys and would be added into crontab. Does anyone have such a script or something similar? i googled, got some results but the scripts didnt suit my needs... Anyway, any help regarding this would come handy... I also have to read how exactly do RSA private keys work... Can somebody give me short, quick explanation?

Thanks

just use rsync with the ssh option.

or if you just want to run a copy scp.

Put them in cron and your done. I mean what exactly are you trying to do?

Keep directories in sync?

tar and copy file's?

as i said, we have 2 servers... now both host some webpages... now, i would like backup these webpages from one server to another, so if i disk brokes i have the data on the other server... i hope i made it clear...

what is rsync?

rsync is an open source utility that provides fast incremental file transfer. rsync is freely available under the GNU General Public License version 2 and is currently being maintained by Wayne Davison.

A good way will be to setup a cron job and use rsync to only transfer the files that have changed beetween the servers.

setup a backup directory on each machine to hold the data for the other:

ex:

rsync -az -e ssh --delete /var/www/html remoteserver:"/var/www/html/server_backup"
