Here is an example of simple backups for Linux.
Create a bash script file /root/backup.sh
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:
Backup can be timed using Crontab. Open crontab:
and add the following line
0 0 * * * root /root/backup.sh
This will create the backup every day at 2400 hours.
