You know, another way to speed up backup is to change the backup blocking factor.<div><br></div><div>I think the default is 63 and if you are going over the network, it is certainly feasible to make it 126.</div><div><br></div>

<div>If I recall, there is an environment variable that can be set/modified to change the blocking factor.</div><div><br clear="all"><div>--tmac<div><br></div><div><b>Tim McCarthy</b></div><div><i>Principal Consultant</i><div style="text-align:left">

Just a lame question here, but how many and type of spindles are behind the volume you are dumping?  If you only have a handful of drives, could be the culprit.<br>

&gt; Stupid question, but isn&#39;t 10Gbe a lot faster with e.g. 9000 byte MTU?  I thought I saw in the original post, a 1500 byte MTU:<br>
&gt;<br>
&gt;<br>
&gt; From original post:<br>
&gt;<br>
&gt; e1a: flags=0x5f4e867&lt;UP,BROADCAST,<br>
&gt; RUNNING,MULTICAST,TCPCKSUM,NOWINS&gt; mtu<br>
&gt; 1500<br>
&gt;<br>
&gt; if the 1500 byte MTU can be changed to 9000 without interrupting service (depends on switch and other configuration, most likely), you might see a speed bump.<br>
&gt;<br>
