If I read You correctly:
You force users to have a single-filesystem TopDir because in this way
You can hard-link together identical files; is this correct?
No way around this? (I do not really care about this optimization
since my servers do not have many identical files).

Again, I'm not quite sure I fully understand (or manage to express
myself fully... after all English is not my first language :) ).
I did set FullKeepCnt=1, FullKeepCntMin=1, IncrKeepCnt=0 and
IncrKeepCntMin=0.
I *hoped* to achieve to always have a single Full, followed by all
Incremental needed to preserve the last one done.
What I would like to achieve is the following sequence:
Sun 1F
Mon 1F 2I
Tue 1F 2I 3I
Wed 1F 2I 3I 4I
Thu 1F 2I 3I 4I 5I
Fri 1F 2I 3I 4I 5I 6I
Sat 1F 2I 3I 4I 5I 6I 7I
Sun 8F
Mon 8F 9I
...
The nI incrementals should be preserved only if needed by the (n+1)I.
Is something like that possible?
If I have two almost-identical full backups on the same media will
they pool space or they will use twice the space of a single Full
backup? (my limited experience seems to point in the direction of
"twice the space", but I am unsure).
Sincerely pooling space between successive backups seems to me more
"interesting" than pooling between possibly unrelated hosts.
Thanks a lot
Mauro
