Why Are There Backup Messages in My Sql Log When No Scheduled Backups Are Running?

While troubleshooting a "while waiting for buffer latch -- type 4" timeout error I checked the SQL Log files and there are a TON of BACKUP DATABASE and success statements. There are no scheduled backups (including T-Logs) anywhere near the time of the message below. No maintenance plans either. I also scripted out all the jobs but didn't find anything.

Perhaps these are some sort of "system backups" (I'm not the man when it comes to reading the log). However because they are running at the same time as the task for which I'm getting the buffer latch type 4 errors I'd like to get them out of the way if possible.

Any help or insight would be most welcome. Thank you!
