So I have had to make a slight change to my BackupPC setup and while I
am able to access new backups in the web interface, I am now unable to
access my older backups.
My old setup was under a FreeNAS Jail, using the FreeBSD pkg of
BackupPC with a nullfs mount from the jail to a ZFS dataset housing
the backups themselves. It worked great for months.
When upgrading from FreeNAS 11 to TrueNAS 12, my jail refused to
upgrade so the option was to either create a new jail or install Linux
in a VM and mount the backups directory over NFSv3. I chose the latter
(ArchLinux) and because Docker is becoming a thing in my LAN,
adferrand/backuppc.
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.
The error message for older backups I am seeing in the web interface
is "Error: Directory /data/backuppc/pc/$host/$baknum is empty".
When trying to access an older backup, BackupPC_ls comes back with,
for example: "bpc_attrib_dirRead: can't open
/data/backuppc/cpool/72/ca/72ca0cc1bf7a179f8c3cdabc187e3887".
Permissions check out (uid 126/backuppc, gid 126/backuppc, umask 027)
so the only thing I can think of is that I need to re-index or
re-build the pool somehow, but I am not familiar enough with BackupPC
command line utilities to know what to do at this point.
Any help would be much appreciated.
Could anyone help with this please? It's making no sense to me:
Sometimes some of the things that go on with BackupPC make no sense to
me either. I've yet to see BackupPC_ls produce any output at all that
makes sense to me but I haven't tried too hard. That said, things can
often work out all right in the end anyway. :)
One of the things to watch out for is indirection, where processes are
using some configured value. This is particularly true when the value
is a filesystem path. That might be helpful and it might not, in this
case, I throw it in because at this stage I can't immediately think of
anything else _concrete_ that might be relevant to your issue. You've
done enough already, however, to give anybody, er, pause for thought.

Is there nobody that can help me with this? Are my backups lost?
My gut feeling is no, your backups will not be lost - unless you do
something rash. But given that
(1) you seem to think that your backups are important to you and
(2) you've been messing about wantonly with the architecture and
(3) it appears that this is your only backup then
what you have done so far seems to me a bit on the rash side.
I am open to paying for one-on-one assistance with this. I would very
much like to salvage this situation, if at all possible.
Well I probably should't pass up an offer like that, but first things
first: what version(s) of BackupPC are we talking about?
