[BackupPC-users] Surprising disk usage, *not* a link problem (I don't think)
2010-09-16 13:09:27
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?
