Sync Large Files (with fixed modification times)

[Black-Byte]

Hi,

i'm using FFS to sync my Virtual Machines to my BackupNAS. It works at the moment but a little bit nasty. Cause the vhd/vhdx files only change the size/timestamp when the vm claims more hd space. So i must use the filecontent detection and this is realy slow. At my setup it takes 3h to detect the changes and 1,5h to copy the files. For me it would be faster if if there was a way to configure an always copy on filetype.
Or is there another way to archive this ?
