    how can i figure out what is happening to sql serverbackups

    Has the database grown considerably?
    Is there anything else running at the same time as your backups?

    Thanks

  • Has the underlying storage changed?  Is your storage experiencing other problems? 
    Are you backing up locally or remotely?  If to a remote location, has your network config changed? 
    Were you backing up compressed, and now uncompressed?

  • Capture the wait statistics during the backups to understand what your server is waiting on. That can very quickly narrow down what's going on. However, everyone has already pointed out the key question. What changed?

    how do I get wait status statistics?

    Here's one example from Paul Randal. Here's an example from my blog. There are others if you look around. Extended Events are the way to get this done.

    Something changed. I'd  focus on what.
