OP5 Monitor - How to automatically delete old backup files

One way to automatically remove old backup files is to create a cronjob.

To create a cronjob to automatically delete old backup files older than 7 days every day at 1 AM please copy/paste the following line and run it as root user.

echo "0 1 * * * root find /path/to/backups/* -mtime +7 -exec rm {} \; > /dev/null 2>&1" > /etc/cron.d/op5-removebackups

Please change /path/to/backups/* to the location of your backup directory.

To manually run the command:

find /path/to/backups/* -mtime +7 -exec rm {} \;

If you only want to list/print the files:

find /path/to/backups/* -mtime +7 -exec ls -l {} \;

It is necessary to delete old backup files to avoid filling up the disk. If the disk or mount is full you will get an error pop-up like below when saving changes.

[Errno 28] No space left on device

If the disk is full OP5 Monitor might also crash and show the below error message:
