Hi,
You could also go from raid1 to raid10.

I think I'd force an fsck just on general principles even though it
will take a long time to complete. Google turns up a few hits

out of curiosity - why don't you just configure /data/BackupPC/TopDir
in config.pl as the TopDir?

I didn't know which host was the problem and didn't think of it. Although
I'll readily admit it seems painfully obvious to me now. :)

Just so you're sufficiently humble... :)

Hi Timothy,
I got the number by observing the output of iotop while file transfer is
running. Also, on BackupPC host summary page, average transfer rate for
full backup is also around 3MB/s
It could be a network bottleneck also, as the customer is using 100Mbps
switch with around 80 PC, not inclu

Hi,
I've spent far too long writing an email and trying to make it make sense and
then discarding it again.
Just one thought I want to rescue: the RStmp file was really *large*
(something like 1.5 GB), your backup trees are really *large* (1.4 TB), your
pool FS is really *full* (27.5 GB free). Ru

In my experience, segfault in libraries usually caused by installing it
from different source.
For example, when I install BackupPC for CentOS, I use the one in EPEL repo.
I make sure that all the libraries (perl and others), only come from CentOS
base repo, and not from other, as installing them
29 matches
