Logs - operational logs filling up the C drive? can DPM backup and purge them like transaction logs?

Our new 2016 Exchange server setup keeps having an issue where the C drive gets below a threshold and external mail stops flowing.  We clear the exchange logs and it is fine for another week or so.    Is backup with data protection manager supposed to backup and purge those logs like it does with transaction logs? If so , how do we get it to do that?   Currently we are running a powershell script to manually delete logs every day.

$IISLogPath="C:\inetpub\logs\LogFiles\"
$ExchangeLoggingPath="C:\Program Files\Microsoft\Exchange Server\V15\Logging\"
$ETLLoggingPath="C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\ETLTraces\"
$ETLLoggingPath2="C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\Logs"

I am told DPM is supposed to be doing this for us?

DPM seems to be clearing the transaction logs as it should.
