Hello, sorry for the lack of information.
Effectively, all I see in the logs is nothing. The computer seems like hanging
without any information logged, and if I'm lucky enough to be using htop by ssh
while it performs a backup, it hangs as I can see the cpu was last at 100%
usage and eventually my ssh session timeouts.
The OS is Ubuntu 8.10 LTS on a P3-1000, using the version of Backuppc that came
in apt-get (3.0.0) and rsync is v. 3.0.0 too.
Also, it does the same when backing up a Windows computer via smb
Here's an example of messages.log:
Jun 20 11:15:24 galactica -- MARK --
Jun 20 11:22:44 galactica syslogd 1.5.0#1ubuntu1: restart.
(yes, I'm a Battlestar Galactica fan, a usb hard drive is identified "viper"
and the next one will be "raptor")
and in backuppc's logs:
2009-06-20 10:16:44 User backuppc requested backup of 192.168.2.91

I tried using burnbx to see if I could reproduce the problem by making the
computer 100% busy for a while, but after 90 minutes I concluded that it was
long enough since backuppc_dump crashes after 15 minutes. Also, I make some
other cpu intensive tasks with this machine, like dvd (re)compiling, or
rtorrent hashing when it completes a hefty torrent file.
Is it possible that my computer is not good enough? If that's the case, I'm
stuck to buy a new computer because this one uses a i815e chipset that limits
it to 512 MB of ram.
I'm starting to despair here because backuppc seems very promising and reliable
for my needs.
