Debian backup bashscript

Question

I'm hosting my own web server, and would like to regularly take a backup of my files. So I decided to write a bash script. However, I'm stuck with this:

#!/bin/bash
# /etc/init.d/backup
# version 0.3.9 2012-08-13 (YYYY-MM-DD)
backup(){

   NOW=`date "+%Y-%m-%d_%Hh%M"`
   tar -czvf  Backup${NOW}.tar.gz /var/www/
   mv Backup${NOW}.tar.gz /home/user/backup/

}
exit 0

I'm wondering how I will run it, how would I make it run every day at certain time.

Any help?

Answer 1

I would suggest using rsync,

Rync Backup script -This will make a backup folder for today ,then sycn yesterdays files todays then it will rsync todays to be backed up.

#!/bin/sh

mkdir -p /storage/backups/`date +\%Y-\%m-\%d`-`date +\%A`/

rsync -avz /storage/backups/`date --date=yesterday +\%Y-\%m-\%d`-`date--date=yesterday    +\%A`/ /storage/backups/`date +\%Y-\%m-\%d`-`date +\%A`/

rsync -avz -e ssh  /var/www/ /storage/backups/`date +\%Y-\%m-\%d`-`date +\%A`/

# Definitions
sevendaysago=$(date --date='6 days ago' +%Y-%m-%d-%A)

# Delete backups from 7 days ago
rm -rf /storage/backups/$sevendaysago

you will need to run this to make scripts run-able

chmod u+x script.sh

In cron you will just need to add via crontab -e

@daily sh backupscript

First, this script will not do anything. You just defined a function backup and did not call it. Just add a line like this below exit 0

backup

Cron is the best tool to run specific tasks/scripts regularly.
