Below is guide how to remote backup using rsync.
1. Install rsync on both client and remote computer:
$ sudo apt-get install rsync
2. Create config file /etc/rsyncd.conf on remote computer:
$ sudo nano /etc/rsyncd.conf
And put these lines into the file:
motd file = /etc/rsyncd.motd log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock [gudang] path = /home/www-metal/ebook/ comment = My Very Own Rsync Server uid = www-metal gid = www-metal read only = no list = yes #hosts allow = 222.165.93.251
Press Ctrl-X, Y, and Enter to exit from nano.
3. Activate rsync
$ sudo nano /etc/default/rsync
Find RSYNC_ENABLE=false line, and change to RSYNC_ENABLE=true
4. Execute rsync
$ sudo /etc/init.d/rsync start
5. And then from client computer, execute this command to get files from remote computer:
$ rsync -avz colekcolek.com::gudang /home/ebook
This command will download (sync) all files in /home/www-metal/ebook on remote computer (colekcolek.com) and save it (sync) to /home/ebook on client computer.
6. Create scheduled job to do sync everyday at 3 am.
$ sudo crontab -e
And type in this line:
0 3 * * * rsync -az colekcolek.com::gudang /home/ebook > /dev/null 2>&1
Don’t forget about “lsyncd”, a live sync daemon that uses rsync. While it may not be the solution for every scenario, most people who land on this page are probably looking for the functionality it provides (real time vs. scheduled job).
It uses inotify to determine when files change, something that’s most likely running on your linux system anyway.
