2022-02-19: Since February 3, 2022 I've been having issues with the transferring of backups from a specific cPanel & WHM system to one of our backup servers. I feel like I made some progress today by replicating the issue (which helped narrow things down) but that was squashed when attempting to work with our data center to further investigate why there are so many dropped packets. I shouldn't have given up, but given that it's Friday I threw in the towel - at least until next week...🥱
Update (2022-02-22): I think we've got it figured out! The --blocking-io flag was causing an issue. I've re-enabled backups on the system. 🤞🏼 when I wake up tomorrow the backups have been taken and transferred to the remote host without issue!
Update (2022-02-23): It looks like the removal of the --blocking-io flag has resolved the issue! Patch is being submitted to the development team!
