Every single day every single one of my WHM server gives backup pruning errors. I have incremental backups configured with SSH.

Unable to prune transport “Backup Transport at DC XYZ”
Error pruning “backup/us-server-xyz/2021-01-31” from “Backup Transport at DC XYZ”:
ssh slave failed: timed out

To the uninitiated I have already read the notice in the email multiple times How to Troubleshoot a Remote Transport Pruning Failure | cPanel & WHM Documentation and I am none the wiser.

The message is bogus yet super annoying. It's bogus because it's pruning! But clearly the backup "finishing up routine" has something wrong with it and I would like to understand what is going on?

Here are some screenshots to share my agony. I love a nice clean green unread email box. Not this red mess.

Here is a screenshot clearly showing a sample server that pruning has taken place.

Please help me clean up my inbox?

First are you doing a full backup daily..
If so how long are you retaining the old version of backups.
setup . Cronjob for this task.
keep 3 copies of your backup Monday , Tues, Wens for example ...
Do Thus would have Delete Monday (Tues , Wens, Thurs)... ect.

Google cronjobs --- Peace!!

Hi!

As written in the docs, the error comes when the pruning process is timing out (5 minutes).
I would look at network issues, backup server/storage performance and permissions on the backup server.
Are there any errors in the logs on the backup server?
