System Backup Plugin - Anacon Script

How can i schedule the "System Backup" plugin to perform regular backups and to retain a number of copies pls?
Is there a script to do this via Anacron plugin?

OK. so i am using the below script in anacron to perform a weekly backup of the system.

#!/bin/bash
    backup_path="/media/854fe912-9f08-423d-9bc8-26a404cae6d0/omvbackup"
    backup_store="/media/854fe912-9f08-423d-9bc8-26a404cae6d0/nas_omvbackup"
    date=$(date +"%d-%b-%Y")


    echo "Performing full system backup..."
    omv-mkconf backup backup    


    echo "Compress system backup..."
    tar -czvf $backup_store/nas_omvbackup-$date.tar.gz $backup_path/
chmod 600 $backup_store/nas_omvbackup-$date.tar.gz


    # Delete files older than 30 days
    echo "Removing obsolete files..."
    find $backup_store/* -mtime +30 -exec rm {} \;
    echo "Done."

I have a bunch of directories i.e. home defined in the USB Backup plugin, how can i trigger by USB Backups via anacron to perform daily backups if the external drive hasn't been disconnected?

I have files named
nas_omvbackup-23-Oct-2014.tar.gz

i renamed to nas_omvbackup-23-Jan-2014.tar.gz to test the below cleanup function but it doesn't delete them.
find $backup_store/* -mtime +30 -exec rm {} \;

what is wrong with the above line pls?

also, the user home directories and a couple of others, i have configured via the USB Backup plugin, but i would like to trigger a daily backup on the basis the USB drive has not been unplugged. What is the command line for trigger the USB Backups pls?

Just enter the command: omv-mkconf backup backup

ryecoaaron, how can i test if the drive is indeed connected before running the job, so to reduce the error emails from when the drive is not connected
