How to schedule a backup in Ubuntu 12.04


Today I will show you how to schedule a backup in Ubuntu 12.04 using cron.

The cron daemon uses the crontab file  (think Task Scheduler in Windows) which allows you to set the backup schedule. The beauty of using cron is that it works ON ALL LINUX DISTRIBUTIONS not just Ubuntu. You don’t even need to install cron as it comes installed by default.

Ok time to get your hands dirty.  Open up a terminal and type “su” and when prompted enter your root password.  Next you want to open up the crontab file so type “nano /etc/crontab” in a terminal.  The crontab file should look similar to the table below.

 

M H Dom Mon Dow User Command
1 9 * * * Root Tar -cvf/media/dev/sdb/backup.tar /home

Where:

M = minutes

H = hours

Dom = every day in the month

Mon = every month

Dow = every day of week (e.g 1-5 would be Monday to Friday inclusive)

User = user who can perform this task

Command = what is getting backed up and where is it getting sent to

Lets explain this a bit. In the above example I have backed up a folder called home (/home) to a folder called backup.tar which is on sdb (/dev/sdb/backup.tar) at 1 minute past 9 everyday in the month, every month.  The authorised user is root and the command to be used is Tar -cvf.

When you have configured the crontab file save it and exit.  Your backup schedule is now set.

How to schedule a backup in Linux Mint 12


Today I will show you how to schedule a backup in Linux Mint 12 so that your precious data is safe.

Linux Mint 12 comes with the Backup Tool shown below which allows you to backup your data and software installed on the system but unfortunately it doesn’t allow you to schedule backups.  For that we need the cron daemon.

The cron daemon uses the crontab file  (think Task Scheduler in Windows) which allows you to set the backup schedule.  The beauty of using cron is that it works ON ALL LINUX DISTRIBUTIONS not just Linux Mint. You don’t need to install cron as it comes installed by default.

Ok time to get your hands dirty.  Open up a terminal and type “su” and when prompted enter your root password.  Next you want to open up the crontab file.

Next type “gedit /etc/crontab” in a terminal.  The crontab file should look similar to the table below.

 

M H Dom Mon Dow User Command
1 9 * * * Root Tar -cvf/media/dev/sdb/backup.tar /home

Where:

M = minutes

H = hours

Dom = every day in the month

Mon = every month

Dow = every day of week (e.g 1-5 would be Monday to Friday inclusive)

User = user who can perform this task

Command = what is getting backed up and where is it getting sent to

So in the above example I have backed up a folder called home (/home) to a folder called backup.tar which is on sdb (/dev/sdb/backup.tar) at 1 minute past 9 everyday in the month, every month.  The authorised user is root and the command to be used is tar -cvf.
