Don, The easiest way is to lower the priority of the amandad daemon that runs on the client. If you are using xinetd, you can just add a nice entry to the amandad service. If you are using BSD inetd, you can use the nice program; change the command from amanda dgram udp wait amandabackup

The default is 1 GB, but specifying 0 will just compute a size based on INT_MAX. I don't think there is any way to specify unlimited chunksize, but you could specify whatever your filesystem limit actually is. (2 TiB for ext2 with 4KiB blocks) Just out of curiosity, why do you care? On
