I am now experiencing this on two different installations where Windows Server 2016 is the host operating system on Dell PowerEdge T620 servers with USB 3.0 interfaces running Windows Server backup.
The machines all host Hyper-V virtual servers.
I have been backing up using Windows Server 2016 Backup to external 8TB USB 3.0 drives. The FULL backups had been taking only about 4 to 6 hours and the incrementals were running in a matter of an hour or so.
Suddenly on two of my different customer installations the Windows Server backup is taking DAYS to run. After about 12 hours one my backups is at 27% of Volume 2 out of 3 volumes.
This all seemed to start AFTER installation of KB4457127 but I cannot say for sure.
I have tried different USB 3.0 external drives, even though the likelihood that two different facilities would suddenly both experience the exact same issue and it be a drive problem seemed unreasonable.
Anyone have any thoughts? Anyone else experiencing this?
