Share on LinkedIn

Here’s a simple little script to backup your web directory. This works on CentOS 7 with no problem. This script backs up the /var/www/html directory.

Create scripts directory

mkdir /home/scripts

Create directory to store backup files

mkdir /home/backups

Create the script

vi /home/scripts/www-backup.sh
FILENAME=www-backup-$(date +%-Y%-m%-d).tgz
tar --create --gzip --file=$DESTDIR$FILENAME $SRCDIR

Description of script elements
Source Directory
Destination Directory
Filename to include date stamp
Create and Compress file using tar command

Ensure execute permissions are set on the script

chmod +x www-backup.sh

Execute the script
To run the script, just type the following from within the /home/scripts directory


This will create a file similar to www-backup-2015317.tgz in your /home/backups directory.

To extract or unzip from backup
Navigate to /home/backups and run the following tar command to extract:

tar -zxvf www-backup-2015317.tgz
