While I'm not familiar with your setup Ivan, an 8 hour runtime would 
seem to indicate configuration problems, like doing all compression 
on the server rather than offloading it to the clients, possibly a 
high rate of network errors due to bad cabling or any combination of 
all the things that Murphy guy can dream up.

Its somewhat of an unwritten rule that a drive big enough to do the 
system at hand will usually do it in about 2 to 3 hours if all else 
is nominal.  If it can't, then its time for a bigger, faster drive.

You might consider posting the amanda.conf and your disklist to see if 
someone can suggest improvements.
