With so big disks today (or with LVM, LSM on Tru64) i'm looking for the 
opposite.

On Tru64 with advfs file system you can have partition and inside
multiple file sets. Each file set is (looks like) a separate file 
system. Backups can be done with the vdump and vrestore.

1.3.1    Filesets, Domains, and Volumes
A fileset follows the logical structure of a traditional UNIX file 
system. It is a hierarchy of directory names and file names, and it is 
what you mount on your system. AdvFS goes beyond the traditional file 
system by allowing you to create multiple filesets that share a common 
pool of storage called a domain. See Section 1.4.1 for information about 
configuring an AdvFS file system and Section 2.4 for information about 
fileset operation.

A domain represents the physical storage layer. It is managed separately 
from the directory structure. You can add or remove volumes without 
affecting the directory structure. See Section 2.3 for information about 
domain management.

Does anyone else can do this? :-)
