How does one copy large (20TB) amounts of data from one cluster to another?<br>
<br>
Assuming that each node in the cluster can only do about 30MB/sec<br>
between clusters and i want to preserve the uid/gid/timestamps, etc<br>
<br>
I know how i do it, but i'm curious what methods other people use...<br>

Just a general survey...<br>
