Re: Scripting the deletion of old backups for OpenNMS

Try putting this script in your /etc/cron.daily directory. This will run it as root once per day.

Subject: [opennms-install] Scripting the deletion of old backups for OpenNMS

Hi,

I've used the OpenNMS wiki to put together a script to run backups of OpenNMS and then delete any old backups older than 30 days, but I can't find how to run the deletion command without sudo credentials. As it stands, I'm pretty sure the script will halt at the point it tries to delete the files, as I'm deleting out of the /opt folder. I have the same problem if I create my backup directory in the /mnt folder as per the wiki. Is it possible to "force" the command so it doesn't require user input? The script is going to be called by our backup system before it performs the server filesystem backup.

#!/bin/bash

# Create timestamp
dsig=`date +%Y%m%d`

# Back up Postgres DB
pg_dump -U opennms -Fc -f /opt/opennms/backup/$dsig-database.pgsql.gz opennms

# Delete all backups older than 30 days
find /opt/opennms/backup -name '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]*.gz' -mtime +30 -delete

Your assistance is much appreciated. I've had difficulty finding an answer online.


Regards, Dominic
