Backup your system using a simple Shell Scripts

This is a super simple way to backup your system without spending a penny. It can be really practical, as backup is always important.

Someone said "When your data does not exist 3 times, that means it's not exist at all". So made some backup and backup your backup 

Here we go:

#!/bin/
date
echo "############### Backup of files on my server ###############"
backupfilename=server_backup_`date '+%Y-%m-%d'`
echo "----- Sql first and dumping current DB -----"
rm -f /tmp/backup.sql
mysqldump --user=youruser --password=yourpassword --all-databases --add-drop-table > /tmp/backup.sql
echo "----- Tar plus zip all files -----"
tar cvf /home/mybackups/files/${backupfilename}.tar /home/www/html/* /tmp/backup.sql
gzip /home/mybackups/files/${backupfilename}.tar
chmod 666 /home/mybackups/files/${backupfilename}.tar.gz
echo "############### Backup done successfully.... ###############"
date
***

Now let explain each line:

• date => we want to see the server date in our log file

• backupfilename=server_backup_`date '+%Y-%m-%d'` => filename of the backup with date

• rm -f /tmp/backup.sql ==> we are removing the old sql backup file generated

• mysqldump => we are backing up all the sql DB again

• tar cvf home/www/html/ /tmp/backup.sql => You are backing up all home/www/html/* and /tmp/backup.sql You can also exclude some paths there with : --exclude='yourpathfile'

NOW let's Executing the Script

Name your file 'backup.sh'
To execute it you need to opne terminal prompt and start with a dot '.' so if you name your file backup.sh you will do .backup.sh
Now let's automate it because you probably don't want to do it manually everyday.
So if you want to auto run it everyday at 23h55 you will open your crontab with crontab -e and you will add this :

55 23 * * * /path/toyourfile/backup.sh >> /path/toyourlogfile/backups.log

and close your crontab terminal with :x
NOTE:
>> /path/toyourlogfile/mybackups.log is not mandatory it only needed if you want to be able too see the log of your backup in case of any error.
If you want to set different time in your cron I recommend you to use this tool is super easy and it will do the job.
