I have a fairly large (171 hosts) backup environment that seems to
be using rather more disk than it should.

GUI says: Pool is 3055.59GB comprising 7361233 files and 4369
directories (as of 9/16 01:33),

df says:

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/local-backups
                      4.0T  3.8T  270G  94% /backups

which is a pretty significant gap.  I've never moved anything
around, so it shouldn't be a linking problem.

The trash is empty.

Running "du -h --exclude='[0-9]*' --exclude=new" in the pc
directory, which *should* ignore only the directories that link to
the pool, gives "2.4G    ."

Running a proper du of the whole tree would take A While, and I'm
not sure my RAM could survive the link checking along with all the
other stuff backuppc is doing.

Any ideas as to what's going on here?

Maybe relevant:

$Conf{BackupPCNightlyPeriod} = 8;

But that still seems excessive?  I've run the nightly manually a few
times, as "sudo -u backuppc /usr/local/bin/BackupPC_nightly 0 255"
(is that the correct syntax for doing that?) and it's taken well
over 24 hours, so splitting it up seems like a probably good idea?
