Created copy taking too much free space

I found a problem using robocopy in PowerShell. I used this tool to backup files from one disk (around 220GB) using command:

robocopy $source $destination /s /mt:8

The problem is that created copy took a lot of free space in the destination location (I stopped making backup when it reached around 850GB). Does anyone know why it has happened?

May be there're some loops involved. robocopy has

Ability to skip NTFS junction points which can cause copying failures because of infinite loops

Try to run with /XJ flag or simply list/log what files are copied to check for loops

See robocopy help and post about it

UP For those who faces same problem:

there were infinite loops which I found using WinDirStat. Mostly it were Application Data/Documments and Settings/Users folders
