That makes sense then why RAID5 is bad for this.

Now you know my trouble with Samba. Sure, if I can read the files they should 
be there, but they're not. This is why I stopped using Samba. It's like 
BackupPC get tired when using Samba and quits when it feels like it because.

I had the original volume / on /dev/md1 and /boot on /dev/md0. I dd'd /dev/md1 
to /dev/sda1 then copied the files for /boot from a mounted /dev/md0 using cp. 
I reinstalled GRUB2 and got the machine to boot. From there I started the 
machine, all my files were intact and things appeared to work yet I noticed my 
graphs had large unfilling holes in them and my compressed pool information is 
not there.

I tried using Rsync on a Linux box, and it gave me some error about not being 
able to read 4 bytes. I'm assuming the user BackupPC is not configured to login 
as root on the machine I'm trying to backup. I've setup SSH keys before, but in 
this I'm assuming there's a lot more involved because the user BackupPC is 
backing things up and doing SSH and not root or my under-privilaged user 
account correct? And wouldn't running ssh-keygen on this machine screw up the 
keys already in place? Haha, that would be bad. And the example you gave, I'd 
need to be able to SSH into the machine as root correct? I don't have the 
ability to SSH in as root on this machine, I have to "sudo su -". Is there a 
way to append the authroized_keys file?

What do you use for backing up localhost? I have Rsyncd setup, but I can use 
some other method like Rsync if needed. I remember the default being tar, but I 
remember hearing many times Rsync being a superior method of backup.

I'll be excited to hear of your findings. You clearly are working with 
higher-grade PCs than me. The fastest machine I've got is a Q6600 @ 3.2GHz and 
that one is the slowest to backup, but it also has the most files being backed 
up I believe; although, it also has an SSD and a 5x640GB RAID5 so I don't know 
what's going on.
