Yes I know those sites but I think this method is stupid as it has no benef=
it=20
of the solution of rsync servers and it  has the following disadvantages:
=2D hosts are backed upo twice =3D> twice more disk activity on the client =
and not=20
cool for the user
=2D if the file foo.doc is on 3 PCs in site A it'l be transferet 3 times to=
 site=20
B and only after that optimized by the pool which is stupid.

if site A crashes, then changing the config of archive hosts to normal host=
=20
should be sufficient rieht?
