Your timing is right - freebsd 7.0 was just released.

RAM RAM RAM! 512MB of ram is definitely your issue here. swapping causes
more periods of head movement which means less periods of head reads/writes
on your disk. With your specs, moving to 1GB+ of ram will be huge.

just a comment, It sure would be nice if LVM supported a raid5 or raidz

the $TopDIR must be on the same volume as the backup files. so if $TopDIR
is /var/lib/backuppc and /var is a 500GB drive then your pc directory needs

the target drive somewhere temporarily and `cp -Rp /var/lib/backuppc

Ok, I finally found and tracked down my problem.
I'm using BackupPC on Ubuntu 7.10, which installs BackupPC 3.0.0.
Turns out, changing the TopDir location does NOT change the location
of the pool files - they are hardcoded to live in /var/lib/backuppc.
According to here:

Ok, I freely admit that I'm in over my head here... I am NOT a perl
programmer. However, here is the method that is puking when trying to
create the links:
sub MakeFileLink
{
my($bpc, $name, $d, $newFile, $compress) = @_;
my($i, $rawFile);
return -1 if ( !-f $name );

It generally means you are waiting for head motion. The controller isn't
going to matter and faster drives only make a little bit of difference.

Hello all,
We're running a BackupPC 3.1.0 installation on CentOS 4 32-bit on a
machine with the following specs:
- Intel Celeron CPU 2.66 GHz
- 512 MB RAM
- BackupPC pool on a single 250 GB ATA 133 drive
We currently running one backup at a time ($Conf{MaxBackups} = 1;).

Hello,
I'm backing up a bunch of machine using BackupPC 3.1.0. Everything has
been working fine for a long time, but since a couple of days backups
for one machine have been failing. The XferLOG for the last partial
backup has this error message:
