Backup hangs at 20% fails after 3 hours with out of memory

Had 11.5 and upgraded to 11.7 build 50088  Now I can't backup.  It started with an error indicating file corruption so I ran chkdsk and solved that.  Now it hangs at 20% for 3 hours and then give me an out of memory error.  The server has 64GB and only around 20% used.
