[Clug-tech] Moving Hardlinked Files Across File System.

I have a RAID NAS that is currently holding 1TB+ of data. The NAS is
failing and I need to exchange it which necessitates getting the data
off of it. The data is your typical rsnapshot scenario in which a full
copy of the most recent data is in a daily.0 directory and data that has
not changed is hardlinked over a series of daily.01 to daily.30 directories.
I know that hard links cannot survive across files systems so simply
copying the data to another 1TB RAID we happen to have on hand is not
going to work. The data will expand to somewhere around 10-15TB and we
do not have that kind of space anywhere. Therefore, I am looking for
I have considered dd but it doesn't appear to be able to work with NFS
mounts - it seems to only want to read from devices.
Does anyone have any bright ideas how I might get my data off this NAS
and preserve the hard links? I assume we're talking about binary copying
of some form...
