Re: [CentOS] Bash script for backup

From: Alan Hoffmeister alangtk@gmail.com

I need a script that will backup & compress the folder /media/system in the folder /media/backups But that's not the problem, I need that only the last 7 backups (last 7 days, yeah I know, cronjob...) will stay in that folder... The script need: 1 - Compress folder /media/system 2 - Store in /media/backups 3 - Name the compressed backup like day_month_year.tar.gzip 4 - Check the other backups and delete backups older than 7 days..

Either name the backups backup.`date +"%u"`. The old files will automaticaly be overwritten by the new ones... Or just after the backup, do something like (untested): find /media/backups -ctime +7 -delete
