    Azure File Sync must fully support synchronization of 100% of ALL valid file and directory names as supported on a Windows Server 2016 file system. Reason is an on-premises backup solution would cause the recall of tiered files, Microsoft recommends using a cloud backup solution to back up the Azure file share. That is only feasible when an enterprise has confidence that 100% of the local Windows file server files/folders are copied up to Azure, and currently that is lacking.

    During testing it was observed the file sync agent was skipping and never successfully copying thousands of files up to Azure which contained a variety of different special characters, all fully supported on Windows Server 2016 file system. We observed warnings such as following in the Event log.
