[OpenAFS] Backup-strategy

[Klaas Hagemann]

every user has its own volume as his home directory.
They only have the write option on their home directory, so that the cannot
administer it.
If they get managed to change the administer rights of a subdirectory, it
would have no affect, because other users won't be able to reach it.
And they do not have a shell to make these things work by standart.
If they change the acl of a subdirectory of their home directory, they can
do that, but it don't need to be backed up.

We use a large HP Surestore, or something like that and Ommniback, so we
want to use dumps for making backups.
Since full dumps are easier to handle than incremental dumps, we want to
take central full dumps. For getting all the date to the central, i want to
use some delta level transfer of afs (like vos release).

That's why i want to have something like read only replicas central, but
they should not be accessable by the users.

Thanks
Klaas
