BACKUPTHREAD
Occurs when a task is waiting for a backup task to finish. Wait times may be long, from several minutes to several hours. If the task that is being waited on is in an I/O process, this type does not indicate a problem.
Detailed Description​
In simple terms a backup is running and an operation is being waited on to complete.
How to reduce this wait​
This wait does not indicate an issue unless your backup has exceeded its usual window by a considerable margin. If this is the case, after checking the backup device is running as normal, consider restarting the backup - but be aware of the impact on possible recoveries. Remember, DBAs earn their money making sure recoveries are possible!
