I've sereveral remote hosts zseries,mt.linux.net that do backups over the net, the others are running on the local network 100/1000Mb the martini-lap is over 100Mb/s as the piteriano, zeta-jones is on 1000Mb/s network.
My hardware config on the backuppc server is:


processor : 3
vendor_id : AuthenticAMD
cpu family : 16
model : 2
model name : AMD Phenom(tm) 9750 Quad-Core Processor
stepping : 3
cpu MHz : 2400.000


8GB ram
SuSE 11.0 x86_64
Backuppc 3.1
Software raid 5 with 3 disks (7.2K rpm) and software raid 0 with 2 disks (7.2Krpm) about that there is a lvm layer.
