  • 'data' is the directory to backup, 'backup' is directory to store snapshots. Backup files on a regular basis using hard links. Very efficient, quick. Backup data is directly available. Same as explained here : http://blog.interlinked.org/tutorials/rsync_time_machine.html in one line. Using du to check the size of your backups, the first backup counts for all the space, and other backups only files that have changed. Show Sample Output

    rsync -av --link-dest=$(ls -1d /backup/*/ | tail -1) /data/ /backup/$(date +%Y%m%d%H%M)/

  • This will create an exact duplicate image of your hard drive that you can then restore by simply reversing the "if" & "of" locations. sudo dd if=/media/disk/backup/sda.backup of=/dev/sda Alternatively, you can use an SSH connection to do your backups: dd if=/dev/sda | ssh user@ssh.server.com dd of=~/backup/sda.backup

    sudo dd if=/dev/sda of=/media/disk/backup/sda.backup

  • Simple way to backup your LDAP entries: put this line on your crontab. The -n switch identifies the dbnum you want to backup (alternatively you can use -b suffix. Check man slapcat for your personal switches)

    slapcat -n 1 > /backup/`date "+%Y%m%d"`.ldif

  • It eases the way of creating cron jobs of backup scripts. Just put this line as cron job, and all your backups are called sequentially. Allows you to forget, when in time, call this backup, just focus on your scripting. Also maintains the way of calling a single backup script when It's needed.


    0
    find /var/scripts -name 'backup*' -exec {} ';'
