Hi G.W.! Thanks for responding.

FWIW I wouldn't use NFS for anything that even vaguely bears a passing
resemblance to a backup system.? In my experience NFS is always flaky.
Even if you do get it more or less under control, there always seem to
be gotchas lurking in there.
Namely?
Well my absolute favourite was when the OOM killer decided that nfsd
was the obvious candidate. A *lot* of machines went down that day.
... apart from an abysmal security model ...
There you go!
Indirection of configuration variables? I'm not so sure that's an issue
with my config, but how would I know?
There are some values like TOPDIR, you could check them.
what you have done so far seems to me a bit on the rash side.
How do you mean?
You had what appears to have been a working backup system. Then you
changed it, and it no longer works.
So I would like to think that point (2) you make is inaccurate and would
hope that in doing so my backups are indeed safe.
Well, perhaps I could have phrased it better. :) But you do seem to
have broken it. When I decided on upgrading to version 4.x of BPC,
I left one machine which ran version 3 *completely* untouched and
installed a *completely* new machine. So then I had three backups
running nightly. Yes, there were two already. After I got BPC4 in
some semblance of order I turned off one of the machines (but it's
still sitting there, turned off, and BPC says it now hasn't been up
for six hundred and twenty-two days). And so on.
... it seems that for certain machines, the entire backup process has
restarted, numbering from 0, with more inaccessible backups. It seems to
be turning into quite a mess and it seems the cleanup system is
spiraling out of control and deleting all my files. Joy.
I have attached a PNG of the current rrdtool graph of the 4-week Pool
Size, which might give you an idea of what is happening. I have a
feeling it will be rejected by the mailing list but I am CC:'ing you ...
The private mail was rejected, we don't accept anything from AS14061,
but I have it. Sometimes I think I never should have patched RRDTool
to do those logarithimic graphs. :/ It doesn't tell me much, but I
don't like the look of those sudden steps in week 44.
... This is BackupPC 4.4.0.
Again, this is the Docker container ...
My preference for all backup machines is to avoid anything resembling
containers, VMs, cloud, ... I want to see the lights flashing on some
hard, bare metal - in the same rack that contains the UPS - and I want
to be able to pick it up and carry it out to the Jeep if I have to.
If I thought there's any risk that old data will get overwritten as a
result of restarting the backup number count from 0 then I'd turn off
the machine and install a new one. If the backups are valuable it's
just not worth the risk, it would be a *lot* cheaper than my fee and
it will Just Work. If you need to go to old backups later on you can
get down and forensically dirty when you have your current backups in
good shape.
