That's really only possible on a single user system. VFX studios usually have large NFS servers (filers) typically running proprietary filesystems, and with hundreds or thousands of clients writing files simultaneously they don't get all laid down on the attached arrays in nice neat chunks representing entire files. Typically they would even try and distribute writes to multiple raid groups/arrays for a single file. Also consider the size, you were able to copy it onto an external drive to recover. Studios don't have a spare, empty filer sitting around to dump the random contents of a few racks worth of disks onto.
