Backup

Here is an example of simple backups for Linux.

Create directories

 mkdir /backup

 mkdir /backup/data

Create a bash script file /root/backup.sh

nano /root/backup.sh

Example file:

tar -cvf /backup/intra/$(date +%y%m%d).tar /data/intra

%y = year

%m = month

%d = day

Backup is automatically saved by date under the /backup/intra directory. A compressed .tar file is named automatically by the date of saving. ("02122014.tar")

Test the backup by running the bash script:

 sh /root/backup.sh

Timed Backup

Backup can be timed using Crontab. Open crontab:

 nano /etc/crontab

and add the following line

 0 0    * * *   root    /root/backup.sh

This will create the backup every day at 2400 hours.
