The time taken to complete this process varies depending on the various factors like network speed, available bandwidth, and number of files and folders. For the rough estimation in the preview release, detection process runs approximately at 10 files/sec.

 Previous Versions is a Windows feature that allows you to utilize server-side VSS snapshots of a volume to present restorable versions of a file to an SMB client.
 This enables a powerful scenario, commonly referred to as self-service restore, directly for information workers instead of depending on the restore from an IT admin.
