Our Website Maintenance Service Delivery is Crashing cPanel Backups: Any Ideas What's Up?

Hey folks, hoping someone here can shed some light on a rather… peculiar issue we're facing. We just rolled out a minor update to our 'Website Maintenance & cPanel Management Services' module. The whole point was to optimize our routine service delivery protocols, make things smoother, faster, you know? Instead, it seems we've taught our module how to trip over its own feet while juggling, specifically when it comes to cPanel backups.

Ever since this 'optimization,' our automated cPanel backups have been failing intermittently, almost exclusively during our designated maintenance windows. It's like the module decides it's too cool for school and tries to do everything at once. We're consistently hitting a 'Disk Quota Exceeded' error, which is hilarious because these accounts have plenty of free space, immediately followed by a 'Backup Process Aborted' message in the cPanel logs. It's truly baffling. Here's a snippet from the logs:

[2023-10-26 03:05:12 -0700] info [cpbackup] Starting backup for user: client_user
[2023-10-26 03:05:15 -0700] error [cpbackup] Disk quota exceeded for /home/client_user/backup/daily/2023-10-26_03-05-12/
[2023-10-26 03:05:15 -0700] info [cpbackup] Backup process aborted for user: client_user
[2023-10-26 03:05:15 -0700] error [cpbackup] cPanel backup failed for client_user: Disk quota exceeded.

Has anyone else experienced something similar with cPanel API interactions or automated maintenance tasks causing these unexpected resource spikes, especially after what should have been a harmless 'service delivery' update? Any insights or troubleshooting tips would be super helpful! Help a brother out please...
