Backup files without locking

Feb 9, 2016 5:49AM PST

Hi.
I need to backup UPD (User Profile Disk ). When I use robocopy, it locks vhdx file and user logs in with temporary profile.
Does robocopy has some flag that avoid locking files? Maybe somebody knows another tool for this purpose.

That's a new feature in Windows Server 2012. Not exactly a Windows Legacy OS.

Since the file backed up needs to be in a consistent state, the user is not allowed to change it during the backup. That makes sense.

https://community.spiceworks.com/topic/427919-user-profile-disk-backup makes me think there's more to it.
I suggest calling your Microsoft account manager for support? They must have foreseen this problem and possibly designed a solution.

I have found one. XXCOPY has flag /SHRW, using it I can backup .vhdx file without locking it.
But it is not free.
