You need to enable extended attributes on your ReiserFS partition.  
They are not enabled by default. Only XFS and JFS enable EA's by  
default.

To do this, add the 'user_xattr' option to your mount options for the  
desired partition(s).

See 'Enabling Extended Attributes' on this page: 
http://beagle-project.org/Gentoo_Installation

Let us know if that works or not for you.

PS -- If you don't have the user_xattr option set on your ReiserFS  
partitions, then that means you don't have any extended attributes on  
them to backup, anyway (since the support is entirely disabled at the  
FS-level).
