Yes.
If you find a sure way NOT to loose data, can you keep your files
on two different drives, on different servers.
Hint: both devices must have the same names,
on both machines, and the same mountpoints.
(i.e. /dev/sdb1, mounted under /failsafe )

No.
On a NIC can you define more than one IP Address.
i.e. :
eth0 10.10.10.1,
eth0:0 10.10.10.33,
eth0:1 10.10.10.167 ... and so on.
Then, all pings on further definied IP's comes ever on eth0 device.
Bye,
