A very easy copy & paste tutorial on how to backup your very important files from your VPS, to another VPS, or linux server.<\/p>\n

This shows to to make a secure connection between servers via SSH, so a password is no longer required between these two servers, and only those two servers to talk to each other.<\/p>\n

Make note of your servers, (this tutorial shows how to back up one VPS, to another VPS), the main server you wish to backup, and the backup server.<\/p>\n

Main
\nxxx.xxx.xxx.xxx<\/p>\n

Backup
\nxxx.xxx.xxx.xxx<\/p>\n

Follow the commands in\u00a0sequence\u00a0to start making backups, and changing\u00a0Blue\u00a0text to the\u00a0appropriate\u00a0user, or IP Address.<\/p>\n

Main>\u00a0ssh-keygen -t rsa -f .ssh\/id_rsa<\/p>\n

-t is the encryption type
\n-f tells where to store the public\/private key pairs. In this case, the .ssh directory on home is being used<\/p>\n

A password will be asked; leave this part blank, just pressing <enter>
\nNow, go the .ssh directory, and you will find two new files: id_dsa and id_dsa.pub. The last one is the public part. Now, copy the public key to the server machine<\/p>\n

Main>\u00a0cd .ssh
\nMain>\u00a0scp id_rsa.pub\u00a0user@Backup:~\/.ssh\/id_rsa.pub<\/p>\n

Of course, this time you will need to enter the password.
\nNow, login into the server machine and go to the .ssh directory on the server side<\/p>\n

Main>\u00a0ssh\u00a0user@Backup
\nBackup>\u00a0cd .ssh<\/p>\n

Now, add the client\u2019s public key to the know public keys on the server<\/p>\n

Backup>\u00a0cat id_rsa.pub >> authorized_keys
\nBackup>\u00a0chmod 644 authorized_keys
\nBackup>\u00a0rm id_rsa.pub
\nBackup>\u00a0exit<\/p>\n

Some useful Backup commands:<\/p>\n

    \n
  1. rsync -ravz -e \u201cssh\u201d\u00a0user@Main:\/home \/root\/backup\/$(date +\u201d%d-%m-%Y\u201d)\/<\/li>\n
  2. rsync -ravz -e \u201cssh\u201d\u00a0user@Main:\/etc \/root\/backup\/$(date +\u201d%d-%m-%Y\u201d)\/<\/li>\n
  3. rsync -ravz -e \u201cssh\u201d\u00a0user@Main:\/var \/root\/backup\/$(date +\u201d%d-%m-%Y\u201d)\/<\/li>\n
  4. rsync -ravz -e \u201cssh\u201d\u00a0user@Main:\/var\/lib\/mysql \/root\/backup\/database\/$(date +\u201d%l%p-%d-%m-%Y\u201d)\/<\/li>\n<\/ol>\n

    To make this process\u00a0completely\u00a0automated, crate some cron jobs for these for every hour, day, week, or month, dependent on you needs of backups.
    \nAs well as making another cron job to delete backup files older then 30 days, to keep backup space for daily backups!<\/p>\n

    find \/path\/to\/files\/* -ctime +30 -exec rm -rf {} \\+<\/p>\n
