Automatically Purge Backup Files Off Thumb Drive

Hello, we have a thumb drive attached to a CentOS box and mysql backups are automatically saved to the thumb drive. Is there a way to automatically purge backup files if they are older than say 15 days? I suppose I would need to write a script for this.

The format of the mysql dump files are:

Backup_20070420_0015.sql

Thanks for the help.

Code:

find /mnt/thumb -mtime +15 -iname Backup\*.sql -exec rm -rf {} \;

Ok, so do I just put that in a file, which is rwxr-x-r-x and then add to the cronmanager?

Also, do I need to define what shell I want to use?

You could make it in to a cron script if you like.

Something as simple as this would work:

Code:

#!/bin/bash



find /mnt/thumb -mtime +15 -iname Backup\*.sql -exec rm -rf {} \;

You might like to add a check to see if the USB Key is actually mounted:

Code:

#!/bin/bash



SCRUBDIR='/mnt/thumb'



# Check if it's mounted first

MOUNTED=`cat /etc/mtab | grep $SCRUBDIR`

if [ ! -z "$MOUNTED" ] ; then

        find $SCRUBDIR -mtime +15 -iname Backup\*.sql -exec rm -rf {} \;
