VMBACKUP is a VM backup product that has this level of granularity. Of course
it is not that way right out of the box, but they do provide an exit which
allows a site to code as needed.
For some of these lan/server setups you have to think of them more as a
mainframe from an administrative point of view.
You can have a number of Unix workstations which may or may not have local
files and/or files on one or more central file servers. The end-users do not
have root authority for their machine. An end user can sign onto any
workstation and her/his files will be linked to their session. The files on
the central file server might be owned by an individual or they may be owned
by a group or project.
For example in an University the user might have a home directory with their
personal files, but they might also use files that are associated with an EE
course. They might use other files associated with a chemistry course. Since
the chemistry or EE course files are not owned by an individual but by a group
of people who support the course, you might want the course instructor or TA
to be an administrator for those files. That is with out having to maintain a
dummy id for that purpose or granting full root authority.
In a business setting you might have a group of people working in Personnel.
You might want to let the manager of the group restore any file from her/his
group without given them root authority. Since the file server may be shared
with 10 other departments. One might also want to allow the mis-programmer who
handles the personnel programs to restore or archive for the personnel users
but not for the other users of the file server(s).
You might want to allow Help desk staffers to restore all end-user files
without also granting full root or supervisor privileges
I would assume the same principals would be in effect for other file servers
such as novell.
