I contacted DreamHost to attempt to figure out why four of my domains/WordPress installs running UpdraftPlus stopped deleting backups from DreamObjects on October 15-16 and they recommended that I get support here.
What I'm seeing in the log files is UpdraftPlus finding backup sets to remove from remote storage (DreamObjects), deleting one or two files, and then restarting the backup process without any errors only to finish with no pruning and no email being sent.
Here's a end part of the log file that I think is most relevant to this issue with filenames and bucket names removed:

In the off chance, do you all recognize any problems with UpdraftPlus or my setup here? Any idea what might have changed on October 15-16 that could be causing this? Could this be a php5.4 issue?
Interestingly, I am managing another WordPress install that's hosted on another web host and it's working fine uploading to and deleting from DreamObjects.
