Help With Incremental Backup

gaspower · 09-21-2011, 02:19 PM

Hello,

Need a little help with a .bash file script. Current script below works fine when initiated and creates the backup files of site and database. Where I need help, is that each time I initiate a backup, I would like to have each saving incremented by date and time. This way if I have to go back to a specific time it is available.

Thanks JR

#!/bin/bash
tar -cvjf backup/site.tar.bz2 /home/virtual/site.com/var/www/html/ > /dev/null 2>&1
mysqldump -u site -ppass site > backup/site.sql

Check out the man page for the date command for formatting options, but here's an example:

Code:

#!/bin/bash
DATETIME=`/bin/date +\%Y-\%m-\%d-\%H.\%M.\%S`
tar -cvjf backup/site.$DATETIME.tar.bz2 /home/virtual/site.com/var/www/html/ > /dev/null 2>&1
mysqldump -u site -ppass site > backup/site.$DATETIME.sql
