Backup Slowness_Avamar

Hi Guys,

Recently I took over backup jobs.And I am not familiar with Avamar backup. Recently, I encounter backup slowness issue which take 5hrs to backup 400GB data.

I have list down some logs for your guys reference. Actually, I have raised request to EMC, However, the support mentioned that its relate to number of reparse links/junctions which may affect client's file scan rate performance. But I don't believe that it's the real cause. 

For the part 1 logs, I just list up some traversing junctions as example, EMC support have provide solution like add --x31 =+ 33554432 in the avtar.cmd

For the part 2 logs, I list up some logs relate to catch update, through the whole logs, I realized that it takes 2-3 hrs to do this kind of catch update
