This document outlines steps to backup files from an Ubuntu server to a Centos server using Rsync. It involves installing Rsync on both servers, configuring Rsyncd.conf files and passwords, creating a backup folder on the Centos server, and running an initial rsync command to transfer files from Ubuntu to Centos. It also describes setting up a cron job to automatically run the backup every 21 hours and 30 minutes.
Linux server backup solution
- 1. Linux Server Files Backup Solutions Goal: - Backup files in Ubuntu server to Centos server Preparation: - Ubuntu Server (v11.10) - Centos Server(v6.0) Steps: 1. Install Rsync software into Ubuntu - Ubuntu default configuration files include rsync - Configure rsyncd.conf (Detailed configuration please reference relative materials)
- 2. - Above is rsyncd.conf - Set password for rsync - Rsyncd.pass’s format is – name:password, here I set backup:backup
- 3. - This step is really important, to change the permission of rsyncd.pass. 2. Install Rsync software into Centos - Before install rsync, xinetd service should be installed first, because rsync is running based on xinetd. - Start xinetd service - Install rsync services. - Modify rsyncd.conf (Detailed configuration please reference relative materials)
- 5. - Here is my Centos rsyncd.conf - Set password - Format- name:password, here I use backupuser:123456.
- 6. - Change ownership of rsyncd.secrets (Of course you need to change it’s permission to 600 as Ubuntu) - Start rsync service. 3. Start to backup - Put rsync service to start file so that each time when server is restarted, this service will start, too. - Make a file folder named “backup”(or any name you want) in Centos server to receive rsyncd files. - Now we can see, nothing in backup. - Rsync from Ubuntu to Centos, here I chose /home/carol this folder to be downloaded to Centos.
- 7. - Here is the files under /home/carol which I need to rsync to Centos - This is the process of rsync.
- 8. - Now we can see the same files under /home/carol of Ubuntu now have been downloaded to Centos backup file folder. 4. Let backup be automatically.(Here we use cron service) - Start crond service - Set the time of backup, here I set every 21 hours 30 minutes, the backup command will be executed.
