Hi All, I am trying to do remote backup between two linux servers connected by a CAT 6 cable using gigabit interfaces. Without using buffering, i can easily do the backup using the following command. rdump -0auqn -L /sdc1 -f operator@xxxxxxxxxxx:/dev/nst0 /sdc1 However the achievalble throughput is near around 16 MB/s. This is very low as comapared to the throughput supported by my backup system. I came to know of the buffering technique developed at the Imperial College, London which helps doing fast and more reliable remote backups by employing buffering. However whenever i try to use it i get a buffer write error. The following is the command which i am using. dump -0auqn -L /sdc1 -f - /sdc1 | rsh -l operator 192.168.1.2 "buffer -p 75 -o /dev/nst0" The error message is buffer (writer): write of data failed: Bad address bytes to write=10240, bytes written=-1, total written 0K DUMP: Broken pipe DUMP: The ENTIRE dump is aborted. I am not sure what is going wrong. Any help in this regard would be highly appreciated. Thanks in advance.
