Look at your IOWait. Either you are out of memory or likely your disks are dying.

No, looks like you have enough. But you have an IOWait issue. So you need to figure out why. What is causing your disks to freak out?

Figure out what is using your disks. Your system is spending most of its time dealing with storage issues.

That could easily do it, especially if it is not able to complete within the hour window and has overlapping backup jobs.
