You can automate the process of checking the backup logs by using a log monitoring tool like Logwatch or Logrotate. These tools can analyze log files and generate reports on a regular basis.

Logwatch is a free and open-source log analyzer that can be installed on Linux servers. It can generate daily or weekly reports on log files, including the backup logs. To install Logwatch, run the following command:
```bash
sudo apt-get update
sudo apt-get install logwatch
```

Once Logwatch is installed, you can configure it to send you email reports on a regular basis. To do this, edit the `/etc/cron.daily/00logwatch` file and add the following lines at the end:

```bash
# Set the recipient email address
MAILTO="mail@example.tld"

# Generate a report for the backup log file
logwatch --mailto $MAILTO --output mail --range yesterday --logfile /var/log/backup.log
```

This will generate a report for the backup log file and send it to the specified email address. You can customize the report settings by editing the `/etc/logwatch/conf/logwatch.conf` file.
