Preserve file permsisions

If I restore files is there a way to store the user,owner, permissions of the file?
I am worried when restoring a system on linux having to properly set the owner for all the files. root,www-data, and so on.

It should be part of the upcoming 1.5 release:

File backups include file metadata including file modification time, ACLs, alternate data streams etc.

You will lose the file attributes of restored files including things like the original modified dates, etc.

As luca91 said, look out for version 1.5 which will take care of this. I am waiting for this too.
